AudioCodes WebRTC examples

+

Preface

+

+AudioCodes Ltd. provides a WebRTC Gateway functionality on its Session Border Controllers +that supports interworking of calls from clients using WebRTC to standard Voice over IP networks. +

+ +

+For browser-based WebRTC clients, AudioCodes provides a JavaScript API library (the “WebRTC Client SDK”) +to easily integrate WebRTC calling with AudioCodes SBCs. +

+ +

+AudioCodes provides a similar SDK also for native iOS and Android applications. +

+ +

+The WebRTC Client SDK for web, is based on an open-source JavaScript SIP library named “JsSIP”.
+In this document we demonstrate how to use the API to write WebRTC client phones. +

+ +

+WebRTC is one of the components of HTML 5 which is implemented on modern browsers. +

+ +

+Currently the WebRTC Client SDK supports:
+Google Chrome, new Microsoft Edge, Mozilla Firefox, Apple Safari for Mac. +
+Partial supports: iOS Safari and Chrome for Android. +

+ +

+The WebRTC Client SDK uses modern JavaScript version.
+Used JavaScript ES2015 features: class, let, for of, promises and ES2017 features: async/await. +

+ +

+This document is built as a series of fully functional examples. +

+ +

+For educational purposes, the examples use pure JavaScript, working directly with the browser’s HTML DOM elements (without using libraries such as jquery).
+The WebRTC API can only be used when a web page is loaded securely from an HTTPS site. +

+ +

+If you would like to see these examples while operating, you should be able to upload them +to your HTTPS site as well as have access to an AudioCodes SIP SBC server, +configured with WebRTC and session licenses.
+Another option at your disposal is the use of examples already demonstrated in this website.
+You may reconfigure the SBC field with your own server. +

+ +

+View the source code with a browser’s developer tools: Ctrl+Shift+I (Chrome, Firefox) or Alt+Cmd+I (Safari) and select sources +

+ +

+Each example is single HTML page with JavaScript.
+Exiting the page is the same as stopping the program in Windows.
+Reloading the page will restart the program.
+

+ +

+In an HTML file, the following is used: + +


+<body onload = "documentIsReady()">
+
+ +When the page is loaded, the documentIsReady function is called.
+documentIsReady() function plays the same role as main() in C or java languages. +

+ +

Ensure that your browser support WebRTC API

+

Check that your browser supports WebRTC

+

+function documentIsReady() {
+    if( !navigator.mediaDevices || !navigator.mediaDevices.getUserMedia )
+      guiError("WebRTC is not supported");
+    } else {
+      guiInfo("WebRTC is supported");
+    }
+}
+
+ +

Here the result will be shown in an HTML page, instead of a JavaScript console.

+

Sometime opening the JavaScript console is difficult (e.g. Chrome for Android), or impossible (e.g. Chrome for iPad)

+ +

+This simple example is suitable for learning how to see the source code in the browser.
+Please run the example in a Chrome browser (this is similar in Firefox) +

+ +

+Press Ctrl/Shift/I to open the developer tools
+Select 'Sources' tab
+Select 'Page' sub-tab
+
+You can see that sdk/webrtc-api-base/examples/0.webrtc_check_support URL contains: +

    +
  • index.html
    • +
  • phone.js
    • +
+ +Click the 1st and the 2nd files, and you'll see the source code.
+
+If the JavaScript code is compressed you can click the {} icon to expand.
+Later we'll describe how to debug JavaScript code, +or locally change it using 'overrides' +

+ +

+In phone.js you can see how to get a reference to an HTML element defined in index.html,
+and how to change style and innerHTML values. +

+

+function guiError(text) { guiStatus(text, 'Pink'); }
+function guiInfo(text) { guiStatus(text, 'Aquamarine'); }
+
+function guiStatus(text, color) {
+    let line = document.getElementById('status_line');
+    line.setAttribute('style', `background-color: ${color}`);
+    line.innerHTML = text;
+}
+
+ +

Checking available devices (camera, microphone)

+

Check for available devices

+

To make a phone call you need to at least have a microphone and headphones.
+A video call also requires a web camera.
+In this example, we check for the presence of these peripherals.

+

You can see here that WebRTC API uses the more modern callbacks in the form of 'Promise' +(.then .catch)

+ +

+function documentIsReady() {
+    // Check devices: microphone must exist, camera is optional
+    checkAvailableDevices()
+        .then((camera) => {
+            let str = 'microphone is found'
+            if (camera)
+                str = 'microphone and camera are found'
+            guiInfo(str);
+            console.log(str)
+        })
+        .catch((e) => {
+            guiError(e);
+            console.log(e);
+        })
+}
+
+// Check WebRTC support. Check presence of microphone and camera.
+function checkAvailableDevices() {
+    if (!navigator.mediaDevices || !navigator.mediaDevices.getUserMedia)
+        return Promise.reject('WebRTC is not supported');
+    let cam = false,
+        mic = false,
+        spkr = false;
+    return navigator.mediaDevices.enumerateDevices()
+        .then((deviceInfos) => {
+            deviceInfos.forEach(function (d) {
+                console.log(d);  // print device info for debugging
+                switch (d.kind) {
+                    case 'videoinput':
+                        cam = true;
+                        break;
+                    case 'audioinput':
+                        mic = true;
+                        break;
+                    case 'audiooutput':
+                        spkr = true;
+                        break;
+                }
+            });
+            // Chrome supports 'audiooutput', Firefox and Safari do not support.
+            if (navigator.webkitGetUserMedia === undefined) { // Not Chrome
+                spkr = true;
+            }
+            if (!spkr)
+                return Promise.reject('Missing a speaker! Please connect one and reload');
+            if (!mic)
+                return Promise.reject('Missing a microphone! Please connect one and reload');
+
+            return Promise.resolve(cam);
+        });
+}
+
+ +

Very simple click to call phone

+ +

In this example, we start using the AudioCodes WebRTC API
+

The click to call phone (for outgoing calls only), uses AudioCodes SBC anonymous user mode

+

The phone call is initiated from an anonymous user to a registered user.
+Note: an anonymous user cannot call another anonymous user.

+ +

+The phone doesn't ask the user for any information and does not save it in the browser.
+In doing so, it can be safely used in public computers such as the ones available at airports, internet Cafes, or public libraries. +

+ +

+To use this phone, a Web Master should insert a link to it in an HTML page.
+The HTML page with the link may be in an HTTP or HTTPS site.
+The phone page should be used in an HTTPS site. +

+ +

Run click-to-call example (with HTML link)

+

Run click-to-call example (with HTML form)

+

Run click-to-call example (with speech recognition/synthesis)

+ +

+The 1st example uses an HTML link to jump to the phone.html page.
+Callee user name or phone number set as URL parameter 'call'
+


+ <a href="https:// ...some site.../phone.html?call=SantaClaus">Click to call SantaClaus</a>
+
+

+ +

+The 2nd example does about the same, but the HTML link string is built dynamically using an HTML form. +

+ +

+The 3rd example is similar to the 2nd, but uses speech recognition.
+While interesting, it is presently at an experimental stage of technology.
+

+ +

+All three examples refer for the same web page: phone.html
+Let's look at its source text
+
+Included JavaScript files:
+

    +
  • ac_webrtc.min.js is a minimized JsSIP library concatenated with AudioCodes API wrapper.
    + You can open the file in notepad++ (or your editor of choice) and see copyright information + belonging to JsSIP and AudioCodes.
    • +
  • phone.js is click-to-call phone code (250 lines)
    • +
  • config.js is a small file with SBC server configurations (5 lines)
    • +
+

+ +

+The phone GUI is simple and consists of the following: +

    +
  • At the top of the page is the status line DIV
    • +
  • In the middle of the page are three panels DIV
    +Only one selected panel is shown, the others are hidden
    • +
  • At the bottom of the page are the video controls
    • +
+

+ +

+Let's look at the source text of the phone.js +

+ +

+The following global variables are used: +

    +
  • phone - instance of AudioCodesUA. Contains API methods. Singletone class
    • +
  • activeCall - represents the current call
    • +
  • callTo - phone number or user name getting from URL parameter 'call'
    • +
+

+ +

+Let's look at the documentIsReady() implementation: +

    +
  • Set loggers. Reading the JavaScript console log we can understand what +occurs during operations.
    • +
  • Check WebRTC support
    • +
  • Get "call" parameter from URL to set callTo variable
    • +
  • GUI initialization. Set callback to a button's click event
    • +
  • Check available devices. Checking that we have a microphone, headphones and a web camera
    • +
  • Init SIP stack. +
      +
    • phone.setServerConfig() - set SBC address and parameters from config.js
      • +
    • phone.setAccount() - for click-to-call used 'Anonimous' user name, and empty string password
      • +
    • phone.setListeners() - set callbacks (listeners) for phone events
      • +
    • phone.init() - starts connecting to SBC
      • +
    +
    • +
+

+ +

API usage, and events sequence

+ +
    +
  • Preparation: set server and account, event listeners
    • +
  • phone.init(). SIP stack initialization, and web socket connecting to SBC server.
    • +
  • callback loginStateChanged 'connected'
    + Called by SIP stack when SBC connection is established.
    + If the SBC server is off-line, or you use an incorrect SBC address, you'll see the following callback:
    + callback loginStateChanged 'disconnected'
    • +
  • phone.call() Send SIP INVITE to SBC
    + Used anonymous mode for Click-to-call phone.
    + Normal SIP phone have to send SIP REGISTER before SIP INVITE.
    • + +
  • callback outgoingCallProgress When we receive the SBC SIP provisional response.
    + For example 180 'Ringing' + Here we could provide some GUI visial effects, or play 'ringing-tone' sound
    • + +
  • callback callShowStreams Means that the callee answered the call (or SBC used early media)
    + Here we need to connect stream was provided by the WebRTC to our video element defined in an HTML page:
    + 
    
+            document.getElementById('remote_video').srcObject = remoteStream;
+
    +
    • +
  • callback callConfirmed Now we know - the call is established
    + We can perform a GUI manipulation: display 'call_established_panel' +
    • + +
  • At the end of a conversation activeCall.terminate()SIP stack sends BYE message
    • + +
  • callback callTerminated + Here we display 'call_terminated_panel'
    + and disconnect from the SBC by phone.deinit() +
    • + +
  • callback loginStateChanged 'disconnected' + It's not an error when phone.isInitialized() == false. +
    • +
+ +

+As you can see, the phone is a state machine. +Using phone API we can initiate some process (SBC connection, SBC registration, calling, hangup call, etc.) +Results are asyncronious, we receive them with a delay, using a callback
+Sometimes the result is not what we wanted.
+For example, the user may not be available. +

+ +

This phone features:

+
    +
  • Supports single outgoing call
    • +
  • Does not support incoming calls
    • +
  • Does not require caller information (used anonimous user)
    • +
+

+ +

+Note: this is a tutorial version of click-to-call phone. +We provide with our SDK a more advanced version. +

+ +

Tiny web phone

+

A tiny web phone example

+

After loading, the phone uses local storage to retrieve user account data (user name, password...)
+ If an account isn't set, it asks the user to enter the required data. +

+ +

After initialization, the phone connects to the SBC server, and sends SIP REGISTER.
+Now the SBC knows where the phone is located, so the phone can receive an incoming call. +

+ +

This phone supports a single concurrent call.
+ If during a call, there is another incoming call, the phone will automatically answer with 'Busy here'
+ Incoming and outgoing audio & video calls are supported.

+ +

This phone's GUI is made up of a status line, a panel and video controls.
+ There are 5 panels: settings, dialer, outgoing call, incoming call and call established.
+ Only one panel is shown at a time while others are hidden.

+ +

The code for outgoing call is the same as in the previous example
+Incoming calls can be answered or rejected

+ +

+activeCall.answer(phone.AUDIO);
+
+ +

+activeCall.reject();
+
+ +

The phone's actual code is fairly small (400 lines)

+ +

Simple web phone

+

A simple web phone example

+ +

+It is still a simple (1100 lines), but more advanced phone. + +

+

Added features:

+
    +
  • Option to change server configuration, phone configuration and user preferences (using local storage)
    • +
  • Hold/un-hold call
    • +
  • Answer to incoming video call with audio, audio and receive only video, audio and two-way video
    • +
  • Start sending/receiving video in audio call. Stop sending video.
    • +
  • Sending DTMF
    • +
  • Incoming call desktop notification.
    • +
  • Redirect incoming call
    • +
  • Reconnection to previously connected server if page is reloaded
    • +
  • Call restoration if page is reloaded during open call
    • +
  • Support SBC switch over between active and redundant devices
    • +
  • Audio playing: ring, ringing-tone, busy-tone, dtmf tones.
    • +
  • Support of Chrome WebAudio autoplay policy
    • +
  • Incoming call with Replaces header
    • +
+ +

Desktop notification

+ +

Desktop notificaiton is now a standard browser API.
Desktop notification document

+

+/-------- Desktop notification (for incoming call) ---------
+function guiNotificationShow(caller) {
+    if (Notification.permission !== "granted")
+        return;
+    guiNotificationClose();
+
+    const options = {
+        image: 'images/old-phone.jpg',
+        requireInteraction: true
+    }
+    desktopNotification = new Notification("Calling " + caller, options);
+    phone.log('desktopNotification created');
+    desktopNotification.onclick = function(event) {
+        event.target.close();
+        desktopNotification = null;
+    }
+}
+
+function guiNotificationClose() {
+    if (desktopNotification) {
+        desktopNotification.close();
+        desktopNotification = null;
+        phone.log('desktopNofification.close()');
+    }
+}
+
+ +

The user will be asked for permission to enable desktop notifications:

+

+// Request permission to use desktop notification (for incoming call)
+if (Notification.permission === 'default')
+    Notification.requestPermission();
+
+ + +

Redirect incoming call

+

User can answer, reject or redirect incoming call

+

Redirect uses SIP response 302 with Contact header to provide redirect address

+

+// redirect incoming call
+call.redirect(recallToAddress);
+
+ +

When calling phone receive callTerminated callback with redirect response,
+it can recall automatically to the provided address.

+

+    callTerminated: function(call, message, cause, redirectTo) {
+        ac_log('phone>>> call terminated callback, cause=%o', cause);
+        . . . . . .
+        if (cause === 'Redirected') {
+            ac_log('Redirect call to ' + redirectTo);
+            let videoOption = call.hasSendVideo() ? phone.VIDEO : phone.AUDIO;
+            activeCall = phone.call(videoOption, redirectTo);
+        }
+    }
+
+ +

Phone will reconnect to a previously connected server if the webpage is reloaded

+

+Before the webpage is closed, the “beforeunload” event is called.
+Make use of that event to save the connected server’s address to the local storage. +

+
Save connected server address
+

+    let serverAddress = phone.getServerAddress(); // currently connected server address
+    if (serverAddress !== null) {
+        let data = {
+            address: serverAddress,
+            time: new Date().getTime()
+        }
+        localStorage.setItem('phoneRestoreServer', JSON.stringify(data));
+    }
+
+ +
Raise priority of previously connected server address
+

+    // load configuration.
+    serverConfig = guiLoadServerConfig();
+
+    // if was page reloading, try reconnect previously connected server
+    let restoreData = localStorage.getItem('phoneRestoreServer');
+
+    // check if there was a saved server data in local storage
+    if (restoreData !== null) {
+        localStorage.removeItem('phoneRestoreServer');
+        let restoreServer = JSON.parse(restoreData);
+        let delay = Math.ceil(Math.abs(restoreServer.time - new Date().getTime()) / 1000);
+        // Check if the stored data has a reasonable timestamp which indicates the there was a refresh not long ago.
+
+        if (delay <=  phoneConfig.restoreCallMaxDelay) {
+            // locate the array location of the server address we found in the stored data in the servers array.
+            let ix = searchServerAddress(serverConfig.addresses, restoreServer.address);
+            if( ix !== -1){
+                ac_log('Page reloading, raise priority of previously connected server: "' + restoreServer.address + '"');
+                // set high priority to the found server in the servers array we so we can be assure this address will be used
+                const HIGH_PRIORITY = 1000;
+                serverConfig.addresses[ix] = [restoreServer.address, HIGH_PRIORITY];
+            } else {
+                ac_log('Cannot find previously used server: ' + restoreServer.address + ' in configuration');
+            }
+        }
+    }
+
+    // proceed with the connection as we have allways done and after we have the highest priority to the desired server.
+    phone.setServerConfig(serverConfig.addresses, serverConfig.domain, serverConfig.iceServers);
+
+ +

Call restoration if page is reloaded during an open call

+

+Before closing the page, the "beforeunload" event is called.
+Here you can check whether the active call exists.
+To restore it, prepare a SIP replaces header and other information, +and save it in the local storage.
+

+
Prepare restore call data
+

+    if (activeCall !== null && activeCall.isEstablished() && phoneConfig.restoreCall) {
+        let data = {
+            callTo: activeCall.data['_user'],
+            video: activeCall.getVideoState(), // sendrecv, sendonly, recvonly, inactive
+            replaces: activeCall.getReplacesHeader(),
+            time: new Date().getTime(),
+            hold: `${activeCall.isLocalHold() ? 'local' : ''}${activeCall.isRemoteHold() ? 'remote' : ''}`,
+            mute: `${activeCall.isAudioMuted() ? 'audio' : ''}${activeCall.isVideoMuted() ? 'video' : ''}`
+        }
+        localStorage.setItem('phoneRestoreCall', JSON.stringify(data));
+    }
+
+ +
Restore call
+

After reloading the page, and registering on the SBC server, + we will check if the saved call exists, if it does, we will try to restore it.

+ +

+    let restoreData = localStorage.getItem('phoneRestoreCall');
+    if( restoreData !== null ){
+        let restore = JSON.parse(restoreData);
+        let delay = Math.ceil(Math.abs(restore.time - new Date().getTime()) / 1000);
+        if (delay > phoneConfig.restoreCallMaxDelay) {
+	        ac_log('No restore call, delay is too long (' + delay + ' seconds)');
+	        return false;
+        }
+        ac_log('Trying to restore call...');
+        let videoOption = (restore.video === 'sendrecv' || restore.video === 'sendonly') ? phone.VIDEO : phone.AUDIO;
+        guiMakeCallTo(restore.callTo, videoOption, ['Replaces: ' + restore.replaces], { 'restoreCall': restore });
+    }
+
+ +

+When a call is restored we will also restore its Hold & Mute states +

+ +

+let restore = activeCall.data['restoreCall'];
+if (restore) {
+    if (restore.hold !== '') {
+        if (restore.hold.includes('remote')) {
+            ac_log('Restore remote hold');
+            guiWarning('Remote HOLD');
+            activeCall.setRemoteHoldState(); // Set JsSIP session internal state for remote hold.
+        }
+        if (restore.hold.includes('local')) {
+            ac_log('Restore local hold');
+            guiHold();                       // Send hold re-INVITE
+        }
+    } else if (restore.mute !== '') {
+        if (restore.mute.includes('audio')) {
+            ac_log('Restore mute audio');
+            guiMuteAudio();
+        }
+        if (restore.mute.includes('video')) {
+            ac_log('Restore mute video');
+            guiMuteVideo();
+        }
+    }
+}
+
+ + +

Support AudioCodes SBC switch over

+

+Two SBC's in active and standby mode are used to support High Availability.
+If the active SBC fails, the standby SBC will take-over.
+From the client's point of view, the SBC connection will be closed/failed and then reconnect and re-login to the SBC.
+This can occur during a call (there will be a short pause in the transmission of sound.)
+In this case the UI state shouldn't be changed (stay in an open call). + +


+    loginStateChanged: function(isLogin, cause) {
+         switch (cause) {
+             . . . .
+             case "login":
+                 ac_log('phone>>> loginStateChanged: login');
+                 . . . . .
+                 if (activeCall !== null && activeCall.isEstablished()) {
+                     ac_log('Re-login done, active call exists (SBC might have switched over to secondary)');
+                     guiShowPanel('call_established_panel');
+                 }

Audio player

+

To make the phone resemble a stationary one, a sound was added for the ringing and phone +tones (ringing, busy, DTMF)

+

+Because WebRTC can only be used in a modern browser, audio playing uses AudioContext API.
+Simple AudioPlayer implementation provided in utils.js +

+ +

Sounds can be loaded from site, using the following encoding: mp3, aac and ogg (vorbis).
+For modern browsers it’s not necessary to provide the same sound in alternative encodings, just use mp3 and check that it works on all supported browsers. +

+ +

+Tones can be generated by generateTone() or generateTonesSuite() methods. +

+ +
Audio player: create, initialize, download sounds from the site, generate tones
+

+    let SoundConfig = {
+        generateTones: {
+            // Ringing and busy tones vary in different countries, so those should be defined accordingly.
+            // Here f - frequency Hz, t - duration seconds
+            ringingTone: [{ f: 425, t: 1.0 }, { t: 4.0 }],
+            busyTone: [{ f: 425, t: 0.48 }, { t: 0.48 }],
+            disconnectTone: [{ f: 425, t: 0.48 }, { t: 0.48 }],
+            autoAnswerTone: [{ f: 425, t: 0.3 }]
+        },
+        downloadSounds: [
+            { ring: 'ring1' }, // ring1 by default (user can select other ring)
+            'bell'
+        ],
+		. . .
+    }
+	
+
+    let audioPlayer = new AudioPlayer();
+    audioPlayer.init(ac_log);
+
+    audioPlayer.downloadSounds('sounds/', SoundConfig.downloadSounds)
+        .then(() => {
+            // Concatenate user defined tones and DTMF tones defined in audioPlayer.
+            let tones = Object.assign({}, SoundConfig.generateTones, audioPlayer.dtmfTones);
+            return audioPlayer.generateTonesSuite(tones);
+        })
+        .then(() => {
+            ac_log('AudioPlayer: sounds are ready:', audioPlayer.sounds);
+        })
+
+ + +
Play a sound
+

+   audioPlayer.play({ name: 'ringingTone', loop: true, volume: 0.3 });
+
+ +

+   audioPlayer.play({ name: 'busyTone', volume: 0.3, repeat: 4 });
+
+ +
Stop playing
+

+   audioPlayer.stop();
+
+ + +
Support of Google Chrome’s WebAudio autoplay policy
+

+The following methods have been added: +

    +
  • isDisabled() – This checks whether autoplay is disabled or not.
    • +
  • enable() – This enables autoplay. It will only succeed when called after the user has interacted with an event prompting them to enable autoplay (for example, a button click).
    • +
+

+ +

+function guiEnableSound() {
+    if (!audioPlayer.isDisabled())
+        return;
+    audioPlayer.enable()
+        .then(() => {
+          ac_log('Sound is enabled')
+        })
+        .catch((e) => {
+            ac_log('Cannot enable sound', e);
+        });
+}
+
+ +

Configure sounds/tones using config.js

+

+The phone can use various ringback, busy and incoming calls ringtones (sounds)
+Therefore, it is convenient to adjust the sound without rebuilding the phone, by modifying the SoundConfig in the file config.js +

+ +

+let SoundConfig = {
+    generateTones: {
+        // Phone ringing, busy and other tones vary in different countries.
+        // Please see: https://www.itu.int/ITU-T/inr/forms/files/tones-0203.pdf
+
+        /* Germany
+        ringingTone: [{ f: 425, t: 1.0 }, { t: 4.0 }],
+        busyTone: [{ f: 425, t: 0.48 }, { t: 0.48 }],
+        disconnectTone: [{ f: 425, t: 0.48 }, { t: 0.48 }],
+        autoAnswerTone: [{ f: 425, t: 0.3 }]
+        */
+
+        /* France
+        ringingTone: [{f:400, t:1.5}, {t:3.5}],
+        busyTone: [{ f: 400, t: 0.5 }, { t: 0.5 }],
+        disconnectTone: [{ f: 400, t: 0.5 }, { t: 0.5 }],
+        autoAnswerTone: [{ f: 400, t: 0.3 }]
+        */
+
+        /* Great Britain */
+        ringingTone: [{ f: [400, 450], t: 0.4 }, { t: 0.2 }, { f: [400, 450], t: 0.4 }, { t: 2.0 }],
+        busyTone: [{ f: 400, t: 0.375 }, { t: 0.375 }],
+        disconnectTone: [{ f: 400, t: 0.375 }, { t: 0.375 }],
+        autoAnswerTone: [{ f: 400, t: 0.3 }]
+    },
+    downloadSounds: [
+        { ring: 'ring1' }, // ring1 by default (user can select other ring)
+        'bell'
+    ],
+    play: {
+        outgoingCallProgress: { name: 'ringingTone', loop: true, volume: 0.2 },
+        busy: { name: 'busyTone', volume: 0.2, repeat: 4 },
+        disconnect: { name: 'disconnectTone', volume: 0.2, repeat: 3 },
+        autoAnswer: { name: 'autoAnswerTone', volume: 0.2 },
+        incomingCall: { name: 'ring', loop: true, volume: 1.0, dropDisabled: true },
+        incomingMessage: { name: 'bell', volume: 1.0 },
+        dtmf: { volume: 0.15 }
+    }
+}
+
+ +

+See code example above how SoundConfig used in methods: downloadSounds and generateTonesSuite +

+ +

+SoundConfig used for all sound plays: +

+ +

+audioPlayer.play(SoundConfig.play.outgoingCallProgress);
+audioPlayer.play(SoundConfig.play.busy);
+audioPlayer.play(SoundConfig.play.disconnect);
+audioPlayer.play(SoundConfig.play.autoAnswer);
+audioPlayer.play(SoundConfig.play.incomingCall);
+audioPlayer.play(SoundConfig.play.incomingMessage);
+
+ +

+To playing DTMF added key name: +

+

+audioPlayer.play(Object.assign({ 'name': key }, SoundConfig.play.dtmf));
+
+ + + + +

Incoming call with Replaces header

+

+Incoming INVITE can contain Replaces header (used for attended transfer).
+In the case "incomingCall" callback argument replacedCall points to the call that should be replaced.
+(for other cases replacedCall is null) +

+

+Developer should close replacedCall call, and auto answer to incoming call.
+The new call should visually replace previous call in GUI. +

+ +

+incomingCall: function (call, invite, replacedCall) {
+    ac_log('phone>>> incomingCall', call, invite, replacedCall);
+    . . . .
+    // If received INVITE with Replaces header
+    if (replacedCall !== null) {
+        ac_log('phone: incomingCall, INVITE with Replaces');
+
+        // close the replaced call.
+        replacedCall.data['terminated_replaced'] = true;
+        replacedCall.terminate();
+
+        // auto answer to replaces call.
+        activeCall = call;
+        activeCall.data['open_replaced'] = true;
+
+        // Try to use the same video option as was used in replaced call.
+        let videoOption = replacedCall.hasVideo() ? phone.VIDEO : (replacedCall.hasReceiveVideo() ? phone.RECVONLY_VIDEO : phone.AUDIO);
+        activeCall.answer(videoOption);
+        return;
+    }
+}
+
+ + +

Call history

+

To keep a user's call history, it's better to use IndexedDB.
If 'user name' is changed, the phone will clear its call history.
Call history is saved in a database, and also set in 'call_log_panel' as an unordered list

+

+
+/**
+ * Database with single store and with copy of the store in memory - objects list
+ * Purpose: make the list persistent.
+ * Key is part of record, based on current time, unique and has name 'id'
+ * Number of objects in store is limited, oldest objects will be deleted.
+ * If needed, additional stores can be added: override open(),
+ * and use get(), put(), clear(), delete() methods with store name.

+        let useTimestamp = phoneConfig.addLoggerTimestamp;
+        let useColor = ['chrome', 'firefox', 'safari'].includes(phone.getBrowser());
+
+        ac_log = function () { // Assign ac_log global variable. It's phone logger.
+            let args = [].slice.call(arguments);
+            let firstArg = [(useTimestamp ? createTimestamp() : '') + (useColor ? '%c' : '') + args[0]];
+            if (useColor) firstArg = firstArg.concat(['color: BlueViolet;']);
+            console.log.apply(console, firstArg.concat(args.slice(1)));
+        };
+        let js_log = function () {
+            let args = [].slice.call(arguments);
+            let firstArg = [(useTimestamp ? createTimestamp() : '') + args[0]];
+            console.log.apply(console, firstArg.concat(args.slice(1)));
+        };
+
+        phone.setAcLogger(ac_log);     // It's AudioCodes SDK logger.
+        phone.setJsSipLogger(js_log);  // It's JsSIP stack logger.
+    }
+
+

+ +

+Note: no need to add a timestamp to the log.
+You should enable show console log timestamps in browser. +

+

+Our customers send us logs with discovered problems.
+To our surprise, none of them sent logs with a timestamps.
+Therefore, we decided that we would add the timestamp string before each log entry in our example logger function. +

+ +

+By default, the log is printed in the browser console window.
+It can be sent via websocket to a server.
+We added the websocket logger to our examples: + +


+    function setWebsocketLoggers(url) {
+       return new Promise((resolve, reject) => {
+           let ws = new WebSocket('wss://' + url, 'wslog');
+           ws.onopen = () => { resolve(ws); }
+           ws.onerror = (e) => { reject(e); }
+       })
+           .then(ws => {
+               const log = function () {
+                   let args = [].slice.call(arguments);
+                   ws.send([createTimestamp() + args[0]].concat(args.slice(1)).join() + '\n');
+               };
+               ac_log(`Sending log to "${url}"`);
+               ac_log = log;               // It's phone logger.
+               phone.setAcLogger(log);     // It's AudioCodes SDK logger.
+               phone.setJsSipLogger(log);  // It's JsSIP stack logger.
+           })
+    }
+
+

+ +

+If the websocket logger cannot connect to the cloud service, the browser console is used. +
+ +


+    function documentIsReady() {
+        // Load configurations
+        serverConfig = guiLoadServerConfig();
+        phoneConfig = guiLoadPhoneConfig();
+        userPref = guiLoadUserPref();
+    
+        // Set logger
+        if (!serverConfig.logger) {
+            setConsoleLoggers();                      // Use console logger.
+            startPhone();
+        } else {
+            setWebsocketLoggers(serverConfig.logger)  // Use websocket logger.
+                .catch((e) => {
+                    setConsoleLoggers();              // Cannot connect. Use console logger.
+                    ac_log('Cannot connect to logger server', e);
+                })
+                .finally(() => {
+                    startPhone();
+                })
+        }
+    }
+
+

+ + +

Access to internal WebRTC objects

+

After the call is established, you have RTCPeerConnection using method call.getRTCPeerConnection(),
+and local and remote WebRTC media streams using methods call.getRTCLocalStream() and call.getRTCRemoteStream(). +

+Note: Developers may call the WebRTC API directly or use the provided SDK functions.
+The functions called via phone.getWR() (webrtc wrapper) and return Promise.
+View the examples below.

+    let ts = conn.getTransceivers();
+    let at = getTransceiver(ts, 'audio');
+    let vt = getTransceiver(ts, 'video');
+    ac_log(`Transceivers: (${ts.length}) audio ${getTransInfo(at)} video ${getTransInfo(vt)}`, ts);

+            return t;
+        if (t.receiver !== null && t.receiver.track !== null && t.receiver.track.kind === kind)
+            return t;

+    return null;
+}
+
+function getTransInfo(t){
+    return t === null ? 'none' : `d=${t.direction} c=${t.currentDirection}`;

+                    str += ' {';
+                    let first = true;
+                    for (let key of Object.keys(now)) {
+                        if (first) first = false;
+                        else str += ',';
+                        str += (key + '=' + now[key]);
+                    }
+                    str += '} \r\n';

+        .then(() => {
+            ac_log(str);
+        });
+}
+
+ + + +

Blind call transfer

+
Transferor
+ +

+To transfer a call, the phone places the current call on hold and sends a SIP REFER message +to the active call (thereby requesting it to initiate a new call to a different destination). +

+ +

+async function blindTransfer(transferTo) {
+    ac_log('blind transfer ' + transferTo);
+
+    //  wait until active call be on hold
+    while (activeCall !== null && !activeCall.isLocalHold()) {
+        try {
+            await activeCall.hold(true);
+        } catch (e) {
+            await new Promise(resolve => setTimeout(resolve, 1000));
+        }
+    }
+    if (activeCall === null)
+        return;
+
+    // send REFER
+    activeCall.sendRefer(transferTo);
+}
+
+ + +

+After a call transfer has initialized, the phone will check the process by using the “transferorNotification” callback.
+If the call transfer fails, it will un-hold the current call.
+If the call transfer succeeds, it will end the current call.
+

+ + +

+transferorNotification: function (call, state) {
+    switch (state) {
+        case 0:    // "in progress": REFER accepted or received NOTIFY 1xx
+            break;
+
+        case -1:   // "failed": REFER rejected or received NOTIFY >=300
+            call.hold(false); // un-hold active call
+            break;
+
+        case 1:   // "success" received NOTIFY 2xx
+            guiHangup(); // terminate active call
+            break;
+    }
+}
+
+ +
Transferee
+

+When the phone receives a REFER message it will call the address extracted from the Refer-To header. +

+ +

+To receive a REFER message, use the “transfereeREFER” callback. +This callback will allow the phone to accept or reject incoming REFER messages. +

+ +

+


+transfereeRefer: function (call, refer) {
+    if (transferCall === null) {
+        ac_log('phone>>> transferee incoming REFER: accepted');
+        return true;
+    } else {
+        ac_log('phone>>> transferee incoming REFER: rejected, because other transfer in progress');
+        return false;
+    }
+}
+
+

+ +

+If a REFER message is accepted, the SIP stack will automatically create a new call and start the calling process.
+Developers should use the "transfereeCreatedCall" callback to receive a reference to the newly created call object.
+Note: the transferee’s phone will have two calls working simultaneously, i.e. the call in which the REFER was received and a new outgoing call to the REFER’s specified destination. +

+ +

+


+transfereeCreatedCall: function (call) {
+    ac_log('phone>>> transferee created call', call);
+    transferCall = call; // Used until call will be established
+    guiInfo('call transferring to ' + call.data['_user']);
+    . . . . .
+}
+
+

+ + +

Receiving NOTIFY in/out of dialog

+

+Developers should use the "incomingNotify" callback to receive incoming NOTIFY.
+

+ +

+Note: to receive incoming in dialog NOTIFY used modified JsSIP.
+(because it's not standard SIP extension) +

+ +

+Partial implementation of Broadsoft call control: +

+ +

+


+incomingNotify: function (call, eventName, from, contentType, body, request) {
+    ac_log(`phone>>> incoming NOTIFY "${eventName}"`, call, from, contentType, body);
+    if (call === null)
+        return false; // skip out of dialog NOTIFY.
+    if (eventName !== 'talk' && eventName !== 'hold')
+        return false; // skip unsupported events
+    if (activeCall === null)
+        return false; // skip illegal state.
+
+    if (eventName === 'talk') {
+        if (!activeCall.isEstablished() && !activeCall.isOutgoing()) {
+            ac_log('incoming NOTIFY "talk": answer call');
+            // Choose the best available video option.
+            let videoOption = activeCall.hasVideo() ? (hasCamera ? phone.VIDEO : phone.RECVONLY_VIDEO) : phone.AUDIO;
+            guiAnswerCall(videoOption);
+        } else if (activeCall.isEstablished() && activeCall.isLocalHold()) {
+            ac_log('incoming NOTIFY "talk": un-hold call');
+            call.hold(false);
+        } else {
+            ac_log('incoming NOTIFY "talk": ignored');
+        }
+    } else if (eventName === 'hold') {
+        if (activeCall.isEstablished() && !activeCall.isLocalHold()) {
+            ac_log('incoming NOTIFY "hold": set call on hold');
+            activeCall.hold(true);
+        } else {
+            ac_log('incoming NOTIFY "hold": ignored');
+        }
+    }
+    return true; // mark that we 'consume' the NOTIFY.
+}
+
+

+

+ + +

Incoming call custom header usage

+

+Incoming INVITE may contain custom SIP headers.
+In the example we check Alert-Info header. +

+ +

+incomingCall: function (call, invite, replacedCall){
+    . . . .
+    // Check if incoming INVITE contains Alert-Info header.
+    let alertInfo = new AlertInfo(invite);
+    ac_log(`alert-info header ${alertInfo.exists() ? ' exists' : 'does not exist'}`);
+    if (alertInfo.hasAutoAnswer()) {
+        ac_log('*** Used Alert-Info Auto answer ***');
+        // Choose the best available video option.
+        let videoOption = activeCall.hasVideo() ? (hasCamera ? phone.VIDEO : phone.RECVONLY_VIDEO): phone.AUDIO;
+        guiAnswerCall(videoOption);
+        return;
+    }
+    . . . .
+
+ +

+"incomingCall" callback "invite" argument is JsSIP.IncomingRequest
+Developer can get the header(s) by invite.getHeaders('alert-info')
+JsSIP does not provide parser for 'Alert-Info', it is presented as raw header (string)
+We use here custom Alert-Info parser (defined in utils.js).
+In a similar way developer can use any custom SIP header.
+

+ +

Sending/Receiving out of dialog SIP MESSAGE

+ +

+To receive (out of SIP dialog) SIP message used callback "incomingMessage" +

+

+incomingMessage: function (call, from, contentType, body, request) {
+    ac_log('phone>>> incoming MESSAGE', from, contentType, body);
+	. . . . .
+}
+
+ + +

+To send SIP message, used phone.sendMessage() +

+

+function guiSendMessage() {
+    let to = document.querySelector('#send_message_form [name=send_to]').value.trim();
+    let text = document.querySelector('#send_message_form [name=message]').value.trim();
+    if (to === '' || text === '')
+        return;
+    phone.sendMessage(to, text)
+        .then((e) => {
+            ac_log('message sent', e);
+            guiInfo('Message sent');
+        })
+        .catch((e) => {
+            ac_log('message sending error', e);
+            guiError('Cannot send message: ' + e.cause);
+        });
+}
+
+ +

+Note: please check sending result.
+When receiver phone is not registered (off-line), will be catched error,
+because SBC response: 404 "User not found"
+

+ + +

Sending/Receiving in dialog SIP INFO

+ +

+To receive (in SIP dialog) SIP INFO used callback "incomingInfo" +

+

+incomingInfo: function (call, from, contentType, body, request) {
+    ac_log('phone>>> incoming INFO', call, from, contentType, body);
+	. . . . .
+}
+
+ + +

+To send SIP INFO message, used call.sendInfo() +

+ +

+function guiSendInfo() {
+    let info = {test: 'test'};
+    activeCall.sendInfo(JSON.stringify(info), 'application/json');
+}
+
+ +

Local and remote video elements overlapping

+

+Local and remote video elements can overlap each other on the screen.
+Select the video size 'Custom', and use the mouse to +drag the video element, and mouse wheel to increase or decrease its size. +

+

+You can see how it is implemented in the functions: guiSetVideoStyles(), guiUseMouse(), +and functions starts with eventMouse...
+
+

+ +

Set audio and video constraints for browsers

+

+Can be used browser names: "chrome", "firefox", "safari", "other".
+or with os name, e.g. "chrome|windows", "chrome|android", ...
+Possible OS names: "windows", "android", "macos", "ios", "linux", "other". +

+

+If for current browser much 2 entries, the latest replace the previous.
+E.g. if current browser is Safari in iOS for the below example, at first +will be set constraints for "safari", and then they will be replaced by +2nd matched entry "safari|ios". +

+ +

+let constraints = {
+    chrome: { 
+        audio: { echoCancellation: true },
+        video: { aspectRatio: 1.0 }		   
+    },
+	
+    firefox: { 
+        audio: { echoCancellation: true }
+    },
+    
+    safari: {
+        audio: { echoCancellation: false } 
+    },
+	
+    "safari|ios": {
+        audio: { echoCancellation: false } 
+    },
+	
+    other: {
+        audio: { echoCancellation: true }
+    }
+};
+
+phone.setBrowsersConstraints(constraints);
+
+ +

+We don't check in the example if Chrome browser supports for example video constraint "aspectRatio".
+It depends of used operating system, driver and web camera model.
+Therefore, to avoid over constrained error we use optional format of constraints: default or with key word "ideal", and avoid using key word "exact" +

+ + +

Set audio and video constraints for the browser

+For the purpose can be used setConstraints() method to set (or replace previously +used) audio or video constraints for getUserMedia() method
+Constraints can be set for audio (microphone) or video (camera) device. + +

+It is important to use supported constraints and values ranges, or use optional constraints format
+otherwise during call opening (in WebRTC method getUserMedia) will be over constrained error. +
+See also +Capabilities, constraints, and settings +

+ +
setConstraints() method parameters
+
    +
  • + browser [string]:
    +
      +
    • + null – current browser. +
      • +
    • + browser name, one of 'chrome', 'firefox', 'safari', 'other' +
      • +
    • + browser name, vertical line, OS name
      + OS name one of 'windows', 'android', 'macos', 'ios', 'linux', 'other'
      + + 'chrome|windows', 'chrome|macos', …
      +
      • +
    +
    +During SDK initialization it get current browser name, and OS name.
    +They can be obtained using phone.getBrowser() and phone.getOS()
    +When called setConstraints method checked if used browser name or browser-os-name is name of the current browser and OS.
    +Otherwise the method is ignored. +
    • +
  • +type [string] 'audio' or 'video' +
    • +
  • +constraints [object] e.g.:
    +{ echoCancellation: true }
    +{ echoCancellation: { ideal: true } }
    +{ echoCancellation: { exact : true } }
    +
    +
    • +
+ +

+Audio contraints example +

+ +

+let supported = navigator.mediaDevices.getSupportedConstraints();
+let ac = {};
+
+ac_log('Volume is supported: ', supported.volume ? true : false);
+if (supported.volume){
+    ac.volume = 0.7;
+}
+
+ac_log('Echo cancellation is supported: ', supported.echoCancellation ? true : false);
+if (supported.echoCancellation){
+    ac.echoCancellation = true;
+}
+
+if (Object.keys(ac).length > 0){ // Is not empty ?
+    phone.setConstraints(null, 'audio', ac); // null means current browser.
+}
+
+ + +

+Video contraints example +

+ +

+let supported = navigator.mediaDevices.getSupportedConstraints();
+let vc = {};
+
+ac_log('webcam facing mode is supported: ', supported.facingMode ? true : false);
+if (supported.facingMode){
+    vc.facingMode = { ideal: 'user' };
+}
+
+ac_log('webcam aspect ratio is supported: ', supported.aspectRatio ? true : false);
+if(supported.aspectRatio){
+    vc.aspectRatio = 1.0;
+}
+
+if (Object.keys(vc).length > 0){ // Is not empty ?
+    phone.setConstraints(null), 'video', vc);
+}
+
+ +

Add or remove single audio or video constraint for currently used browser

+

+To add or remove single audio or video constraint without modification others +constraints use setConstraint() method. +

+ +

+  // Set audio deviceId for getUserMedia()
+  phone.setConstraint('audio', 'deviceId', 'some-device-id-string'); 
+
+ +

+  // Set audio deviceId for getUserMedia() as "exact" constraint
+  // If such device does not exist getUserMedia() promise will be rejected with OverconstrainedError
+  phone.setConstraint('audio', 'deviceId', {exact: 'some-device-id-string'});
+
+ +

+  // Remove audio deviceId for getUserMedia()
+  phone.setConstraint('audio', 'deviceId', null);
+
+ +

Screen sharing

+ +

+WebRTC supports screen-sharing video stream (See navigator.mediaDevices.getDisplayMedia()).
+We know how to start sending video in audio call, or replace one video track to another in video call.
+We can add custom header to outgoing re-INVITE.
+Combining these techniques, we add screen-sharing support: +

+ +

+ +

+


+let stream = phone.openScreenSharing()
+
+Create screen-sharing stream using navigator.mediaDevices.getDisplayMedia().
+User should select of sharing type: full screen, some window or browser tab. +

+ +

+


+phone.closeScreenSharing(stream)
+
+Close screen-sharing stream previously open by openScreenSharing(). +

+ + +

+call.startScreenSharing(stream)
+
+For audio call it works the same as call.startSendingVideo()
+For video call it replaces sending video track from web camera to screen-sharing video track. +

+ +

+


+call.stopSreenSharing()
+
+Stop screen-sharing video, it can be also stopped by built-in browser button "Stop sharing".
+For audio call it's the same as call.stopSendingVideo().
+For video call will be restored previously sent video track from web camera. +

+ +

+Because screen-sharing can be terminated not only by stopScreenSharing(), but also using built-in in browser button, to phone added new callback: +


+callScreenSharingEnded(call, stream)
+
+The callback used to update GUI
+In multi call phone the same screen-sharing stream can be used in multiple startScreenSharing()
+The callback allows you to keep the usage counter and close the stream if no call is using it. +
+

+ +

+For other side screen-sharing video is usual video.
+To notify the other side that a screen-sharing video is being sent,
+the client sends re-INVITE with the special header:
+X-Screen-Sharing: on
+or
+X-Screen-Sharing: off
+
+If call was replaced, it means the same as X-Screen-Sharing: off. +

+ +

+After page reloading screen-sharing will be restored if the user approves it. +

+

+Please see the API usage in single call and multi call phone prototypes. +

+ + +

SUBSCRIBE dialog

+ +

+In SDK 1.15 added generic SIP SUBSCRIBE dialog
+Used our subscriber/notifier JsSIP extension https://github.com/versatica/JsSIP/issues/708.
+
+Please see usage example in single call phone prototype and phone prototype with ACD. +

Phone prototype with an answering machine

+

Run phone prototype with an answering machine

+

Added feature:

+
    +
  • Automatic Answering Machine
    • +
+ + +

+When a user doesn't answer an incoming call for a set number seconds,
+the answering machine will take its place and answer the call. +

+ +

+First, a greeting message is played.
+The phone has a default greeting,
+or the user can record a custom greeting using their microphone. +

+ + +

+Then a beep sound is played.
+The calling party can now record a voice message and hang up.
+The maximum voice message time is limited. +

+ +

+The recorded message is stored in indexeddb, and will not be lost after the page reload.
+There is a visual notification that the phone +received a new voice message.
+(In our example we changed the color and border color of the button 'Answering Machine') +

+ + +In the panel of the answering machine, the user can: +
    +
  • Turn the machine on or off.
    • +
  • Set a time delay before the start of the operation.
    • +
  • Set the maximum time of the recorded message.
    • +
  • Record the custom greeting, or erase it and use the default.
    • +
  • Listen and delete the recorded messages.
    • +
+ +

+To implement answering machine the following was used: +

    +
  • MediaRecorder API (see class AudioRecorder in utils.js)
    • +
  • IndexedDB support of values with data blob (see class VoiceDb)
    • +
  • + WebRTC 1.0 API replaceTrack to switch audio sender from microphone to the audio player, + without SIP renegotiation.
    + (see class AnsweringMachine, method prepare) +
    • +
  • + Reassignment playing from speaker to audio stream.
    + (See class AnsweringMachine, method playGreeting, play parameter: streamDestination) +
    • +
  • + Added small delay before playing the greeing.
    + Without the delay WebRTC API "swallows" the beginning of the greeting message.
    + (See class AnsweringMachine, method playGreeting, play parameter: startDelay) +
    • +
+

+ +

+Because an answering machine complicates the code, and isn't needed +for all custometers, this is done as a separate example. +

+ +

Phone prototype with OAuth2 authorization

+ +

Run phone prototype with OAuth2

+

Added feature:

+
    +
  • Authorization using OAuth2
    • +
+

+For this example we're using Keycloak server; +an open source software specializing in Identity and Access Management. +

+ +

+The JavaScript phone uses the provided keycloak.js adapter
+

+ + +

Changes in comparison with the phone prototype example

+ +
    +
  • HTML setting_panel +
      +
    • Removed "Account settings" as it is unnecessary in this version.
      + The user name and display name are provided by the Keycloak server.
      +
      • + +
    • Added logout button.
      • +
    +
    • + +
  • Added global variables: +
      +
    • keycloak: Reference to Keycloak server adapter.
      • + +
    • authServerConfig: Authorization server address and parameters.
      • + +
    • authLoginPostponed: boolean flag.
      + Set when the updateToken action has failed,
      + and Keycloak requires a re-login to authorize the user.
      + The re-login directs the user to a keycloak server HTML page for
      + security purposes, so it can't be done while in an active call.
      + In this case we'll wait until the call ends. +
      • + +
    • authTests: string with SBC test names.
      + Allows you to send an invalid access token, using the REGISTER or INVITE message.
      + To disable all tests set an empty string value.
      +
      • +
    +
    • + +
  • Changed phone starting sequence +
      +
    • + Starting out, we call the keycloak adapter initialization to connect
      + to the keycloak server, login, and download the user profile. +
      • +
    • + After which it is called SIP stack initialization.
      +
      • +
    +
    • + +
  • Added checking of SIP response codes for INVITE and REGISTER to detect authorization + problems. +
    • +
+ +

Keycloak adapter initialization

+ +

+let authServerConfig = { url: 'https://webrtcoauth.example.com/auth',
+                         realm: 'demo',
+                         clientId: 'demoClient'};
+
+
+function initializeAuthServer() {
+    ac_log('keycloak: create adapter');
+    keycloak = new Keycloak(authServerConfig);
+
+    keycloak.onTokenExpired = () => {
+        ac_log('keycloak: onTokenExpired callback');
+        updateAuthToken();
+    }
+
+    ac_log('keycloak: init()');
+    keycloak.init({ onLoad: 'login-required' })
+        .then(() => {
+            ac_log('keycloak: initialized');
+            return keycloak.loadUserProfile();
+        })
+        .then(() => {
+            // To disable auto call login() if updateToken() fails.
+            keycloak.loginRequired = false;
+
+            userAccount = {
+                user: keycloak.profile.username,
+                password: '',
+                displayName: keycloak.profile.firstName + ' ' + keycloak.profile.lastName
+            }
+
+            phone.setOAuthToken(keycloak.token);
+
+            initializePhone();
+        })
+        .catch((err) => {
+            ac_log('keycloak: initialization error', err);
+        });
+}
+
+ + +

When using a keycloak adapter, the phone is no longer a Single Page Application (SPA).

+

+The first call to keycloak.init() sends the user to a Keycloak server HTML page +where the user will enter a name and a password.
+Afterwards they’ll be redirected to the page with the phone.
+Loading the phone page calls keycloak.init again but following entering the credentials, it will not redirect the user to a login page. +

+

+Depending on the configuration of the server, the user name and password are rarely required (approximately once every 2 weeks) +

+

+In subsequent calls of the phone page HTML, keycloak.init() will load the phone page directly instead of redirecting to the Keycloak server.
+It will be performed without entering the password, but still adds a few seconds to the startup. +

+ +

REGISTER with access token example

+ +

+The keycloak.js adapter provides a short-lived access token for SBC authorization. +That includes authorization for SIP REGISTER and INVITE messages using an Authorization SIP header. +

+ + +

+

Access token updating

+

+Depending on the configuration of the server, +the short-lived access token will expire after a set amount of time had elapsed +(e.g. every 10 minutes), and will need to be updated by the keycloak server. + +The function is called when: +

    +
  • access token will expire soon
    • +
  • REGISTER authorization has failed
    • +
  • INVITE authorization has failed
    • +
+

+ +

+function updateAuthToken() {
+    ac_log('keycloak: updateToken()');
+    return keycloak.updateToken(-1)
+        .then((refreshed) => {
+            if (!refreshed) {
+                ac_log('keycloak: token is still valid');
+                return;
+            }
+            ac_log('keycloak: token is refreshed');
+            phone.setOAuthToken(keycloak.token); // set access token for AudioCodes API.
+        })
+        .catch((e) => {
+            ac_log('keycloak: Failed to refresh the access token', e);
+            if (activeCall !== null && activeCall.isEstablished()) {
+                ac_log('keycloak: re-login needed. Postponed because there is an active call.');
+                authLoginPostponed = true;
+            } else {
+                ac_log('keycloak: login()');
+                keycloak.login();
+            }
+        });
+}
+
+ + +

Test mode

+

+To test the SBC, a test mode has been added. +The test mode allows you to send REGISTER and INVITE SIP messages +without an Authorization header, or with Authorization header that + contains an incorrect access token value. +

+ +

+To enable the test mode, start the phone, open JavaScript console, and type:
+ +


+    localStorage.setItem('authTests', 'r1 i1');  // set r1 and i1 test
+
+Then reload the phone page.
+When the test mode is used, the console will display:
+ +

+    Warning: USED PHONE TEST MODE: authTests='r1 i1'
+
+ +

+ +

+This can be set for one or more test names. Use space as the delimiter between test names. +

+ +Implemented tests: +
    +
  • user in SIP messages, use the wrong user name of phone owner.
    + When using an incorrect user name, SIP authorization will always fail. +
    • +
  • r1 use in 1st REGISTER with an incorrect token value.
    • +
  • i1 use in initial INVITE with incorrect token value.
    • +
  • r0 don't set to the 1st REGISTER Authentication header
    • +
  • i0 don't set to the initial INVITE Authentication header.
    • +
+

+ +

+To disable the test mode, start the phone, open JavaScript console, and type:
+

+

+    localStorage.removeItem('authTests');
+
+

+And then reload the phone page. +

+

+In a production version, instead of loading the authTests value from local storage, + set an empty string value or completely remove the pieces of code marked with 'test code' comments. +

+ +

Phone prototype with Automatic call distributor (ACD)

+

Run phone prototype with ACD

+

Added feature:

+
    +
  • Work with ACD system
    • +
+ +In this example SIP SUBSCRIBE dialogs used to work with the automatic call distributor (ACD) server. +

+ +

+To parse XML used Scott Means's Pure JavaScript XML parser https://github.com/smeans/pjxml
+MIT license
+The code converted to classes syntax. +

+ +

Multi call phone prototype

+

Run multi call phone prototype

+

Added features:

+
    +
  • Multi call support
    • +
  • Blind call transfer (more natural implementation)
    • +
  • Attended call transfer
    • +
  • Audio conference
    • +
  • Video conference
    • +
+ +

+Provided API supports multi calls.
+Before we did not use this opportunity in phone prototypes,
+because it is significantly complicates GUI and rarely necessary. +

+ +

+Nevertheless it is necessary for 3 way conference and atteneded call transfer. +

+ +

+

GUI scheme

+
    +
  • Status line.
    • +
  • Lines buttons. To select line and show each line status (free, active, or in hold)
    • +
  • Call panel for selected line.
    • +
  • Remote video of all lines receiving video. Optional local video for selected line.
    • +
  • Optional video conference settings and canvas with mixed video from all lines.
    • +
+

+ +

Conference

+

+The conference model is very simple:
+if the phone is in conference mode,
+all callers are in the same conference room and hear (and see) each other. +

+

+All newer calls will be added to this conference room. +

+

+Conference mode can be changed during its operation: audio, audio and video or switched off. +

+ + +

Audio conference

+

+To implement audio conferencing we’ll need to mix audio streams.
+There is an Audio Context API that can help us achieve that. +

+ +

+It used to work exclusively in Mozilla’s Firefox browser, and not in Google’s Chrome browser.
+Finally, in 2019 Chrome’s bug on the subject was fixed. (See Chromium issue 121673, reported in 2012)
+Now we can implement audio conferencing via Google Chrome as well. +

+ +

+In the WebRTC phone, the microphone generates audio stream that is sent to a remote phone.
+To create a conference we will replace it to an audio mixer stream. +

+ +

+Let's consider for example 3-way conferences. +

+ +

+We have 2 open calls:
+1st call A - B
+2nd call A - C
+

+ +

+In normal phone mode, A send its microphone stream to B and C.
+To create an audio conference:
+The 1st call will send to B an audio stream containing audio mixed from the microphone and audio received from C.
+The 2nd call will send to C an audio stream containing audio mixed from the microphone and audio received from B.
+

+ +

+So here we’ll use 2 audio mixers (one mixer per each call).
+We cannot use a single audio mixer to mix all streams and send it to all remote calls because then the remote user will receive and hear their own echo. +

+ +

+Similarly, we can create conferences this way that will include more participants.
+For each call we will send an audio stream mixed from the microphone and other calls. +

+ +

+Note: about tracks and streams.
+ A known problem is that some Web APIs use only streams and others will use only tracks.
+ The stream contains an audio track, or an audio track and a video track. +

+ +

+ WebRTC API supports streams with 2 or more audio tracks.
+ We don't use that (the possibility of sending multiple tracks) for conferencing, instead we send a single stream containing a single audio track (with its audio mixed) +

+ +

+ For audio calls, the phone sends a local stream to a remote phone.
+ When we create a local stream we call WebRTC getUserMedia API (use only stream)
+ The stream contains the microphone audio track.
+ To mix the microphone’s audio with the remote side’s audio we use an Audio Context API (use only streams)
+ Then we get from the mixed stream an audio track and call the WebRTC sender method to replace the track (use only track)
+

+ + + +

Video conference

+ +

+Work with video streams creates a heavy load on the processor so we’ll use a single video mixer for all calls to mix all incoming video streams and the local camera stream. +

+ +

+The same mixed video stream will be sent to all remote calls.
+Each participant will see other participants including themselves (serving as an analogue to the audio conference’s echo). +

+ +

+The browser API is bizarre; we can’t simply mix the video streams the way we do for audio.
+We’ll need to split the video streams to sequences of pictures, +draw them in canvas, using some layout,
+and then recreate the mixed stream from the picture sequence. +

+ +

+User can change the parameters of the video conference during its operation:
+the size of the call's picture, the pictures layout (linear or compact)
+and the number of frames per second (FPS).
+CPU usage varies significantly depending on size and FPS. +

+ +

Audio and video mixer

+ +

+To implement audio and video conference were added class CallAudioMixer and CallVideoMixer (see: utils.js)
+Them use the same class "call" as other API, with one addition:
+in the call instance must be defined integer variable call.data['_line_index'] +

+ +

+


+class CallAudioMixer {
+    // For each call created audio mixer instance.
+    // Аudio context can be taken from audio player.
+    constructor(audioCtx, call)
+
+    // Close mixer, release all resources.
+    close()
+
+    // Get mixed audio stream
+    getMix()
+
+    // Add call to mixer.
+    // Returns true if added, false if the call is already added.
+    add(call)
+
+    // Remove call from mixer
+    // Returns true if removed.
+    // Returns false, if the call was not added, or cannot be removed, because set in constructor.
+    remove(call)
+
+    // Returns string with calls list
+    toString()
+}
+
+

+ +

+


+class CallVideoMixer {
+    // Used single instance for all calls.
+    constructor()
+
+    // Set canvas id.
+    // Set local video element id.
+    // Set remote video element id prefix. (will be added video element index 0, 1, ...)
+    setElements(canvasId, localVideoId, remoteVideoId)
+
+    // Set number of frames per seconds of mixed stream.
+    // For example: 1, 2, 5, 10, 20, 50.
+    // Default: 10
+    setFPS(v)
+
+    // Set calls video layout: 'linear' or 'compact'
+    // Default: 'compact'
+    setLayout(v)
+
+    // Set call video size (pixels)
+    // Default w=160, h=120
+    setSize(w, h)
+
+    // Set call video size (pixels)
+    // size likes: {width: '160px', height: '120px'}
+    setSizes(size)
+
+    // Returns true when mixer is started
+    isOn()
+
+    // Start mixer
+    start()
+
+    // Stop mixer, remove all calls, release resources.
+    // After using stop the mixer can be restarted.
+    stop()
+
+    // Get mixed video stream for added call.
+    getMix(call)
+
+    // Add call to mixer or update send/receive mode.
+    // Returns true if send video was added (should be replaced connection sender track)
+    add(call, send = true, receive = true)
+
+    // Remove call from mixer.
+    // Returns true if removed, false if was not added.
+    remove(call)
+
+    // Resize video layout then changed number of video channels
+    // Used when added/removed local video channel.
+    // Called automatically in methods: add, remove, setLayout, setSize
+    //
+    // Warning: it's designed for 5 lines phone !
+    // Max number of video controls is 6 (including local video)
+    // If you use more lines, please modify this method.
+    resize()
+
+    // Returns string with calls list
+    toString()
+}
+
+

+ +

Phone conference functions

+ +

+The functions work with audio and video mixers and replace connection sender track to mixed stream track,
+or restore original sender track. +

+ +

+


+// GUI switch conference mode: off, audio, audio and video
+function guiConferenceSwitch()
+
+// Start audio conference
+function conferenceStartAudio()
+
+// Stop audio conference
+function conferenceStopAudio()
+
+// Start video conference
+function conferenceStartVideo()
+
+// Stop video conference
+function conferenceStopVideo()
+
+// Add call to conference (audio or audio/video)
+function conferenceAdd(call)
+
+// Remove call from conference (audio or audio/video)
+function conferenceRemove(call)
+
+// Assign line video stream from camera to local video element.
+// Used line set as argument or the first line that send video.
+conferenceSetLocalVideo(lineIndex = -1)
+
+// Print in console conference information.
+function conferencePrint()

Citrix desktop phone prototype

+

+Run Citrix desktop phone prototype +

+ +

+Citrix provides WebRTC Redirection SDK. The SDK can be used to build Electron applications or browser single page applications (SPA). If you use Citrix desktop, see: citrix.com +

+

+Note: Browser SPA only supports audio calls. +

+ +

Citrix SDK conversion

+

+The Citrix SDK file CitrixWebRTC.js (or CitrixWebRTC.min.js) is a Node module. To use it in the browser, it must be converted. +

+

+Notes: +

    +
  • Use the latest Citrix SDK release.
    • +
  • The file CitrixWebRTC.js used in this example was taken from the SDK beta release and could become obsolete.
    • +
+ +

+  npm install --global browserify
+  browserify CitrixWebRTC.js --outfile browserifyCitrixWebRTC.js
+
+ +

JsSIP modification

+

+Citrix API is very close to standard WebRTC API, but not 100% compatible. Therefore, Citrix API JsSIP must be modified. +

+

+Note: +We replaced a few WebRTC API functions to Citrix analogs. Review python script source to see replaced functions. +

+ +
To convert AudioCodes SDK
+

+

    +
  1. Install Python3.
    2. +
  2. Run the following script: +
    
+py citrix_convert.py <ac_webrtc.min.js >citrix_ac_webrtc.min.js
+
    +
    3. +
  3. For debugging, you can replace the obfuscated ac_webrtc.min.js file with the non-obfuscated files acapi.1.?.0.js and citrix_jssip.js
    4. +
+

+ +
To build citrix_jssip.js
+

+   py citrix_convert.py <jssip.js >citrix_jssip.js
+
+
+ +

Citrix cloud Windows configuration

+ +

+

To enable the Citrix SDK
+

+You must set registry in remote Citrix Windows system. Edit Windows registry (use regedit.exe command). +

+ +
    + +
  1. Enable Citrix redirection +
    
+Key Path: HKCU\Software\Citrix\HDXMediaStream
+Key Name: MSTeamsRedirSupport
+Key Type: DWORD
+Key Value: 1
+
    +
    2. + +
  2. Add the Chrome program to the allow list. +
    
+Key Path: HKLM\Software\WOW6432Node\Citrix\WebSocketService
+Key Name: ProcessWhitelist
+Key Type: MULTISZ
+Key Value: chrome.exe

Modification simple phone prototype

+ +

+The provided Citrix phone prototype is a modified simple phone prototype.
+Please compare the simple phone prototype code with this version. +

+
    +
  • Support for video calls removed.
    • +
  • Citrix API in phone.js was used.
    • +
+ +

+Note: The phone.js and citrix_jssip.js does not call the Citrix API directly, but via the citrix_adapter.js wrapper. +

+ + + +

How Citrix phone starts

+
    +
  1. Phone waits for the initialization of the Citrix SDK.
    +Note: There will be error if the browser did not start in Citrix desktop or the desktop is not configured. +
    2. +
    +
  2. +Phone uses the Citrix API to collect available microphones and speakers.
    +
    3. +
    +
  3. +Phone selects microphone and speaker.
    +Citrix API does not work without selected devices +
      +
    • getUserMedia requires microphone deviceId constraints.
      • +
    • AudioElement requires speaker deviceId to be assigned to sinkId.
      • +
    +
    4. +
    +
  4. +Phone attempts to use the same microphone and speaker that were selected before.
    +Note: This does not always work, for example: +
      +
    • When the user detached the USB headset that was previously used.
      • +
    • When the phone starts up for the first time.
      • +
    +In such cases the settings screen opens, allowing the user to select the microphone and speaker. +
    5. +
    +
  5. phone starts JsSIP stack and works in the same way as other phone examples.
    6. +
+ + + +

Dual registration phone prototype

+ +

+Run dual registration phone prototype +

+ +

+JsSIP stack with our CRLF keep alive extension quite quickly (10..20 seconds) +detects websocket disconnection of SBC, +after which it reconnects with the same or with a other SBC. +

+ +

+However, some of our customers want the phone to simultaneously open 2 websocket connections with the main and backup SBC. +

+ +

+The problem is that JsSIP stack can only work with one web socket.
+JsSIP is well maintained and has reliable code.
+Making such drastic changes to it would be difficult to test and can significantly reduce its reliability.
+

+ + +

+However, the customers do not want a phone that can simultaneously call through +the main and backup SBC.
+Only one SBC will be active. (Тhe one to which the JsSIP is connected)
+

+ +

+Without changing JsSIP we will add optional backup SBC module (backup_sbc.js) +to connects to the backup SBC and sending SIP REGISTER sequence.
+If necessary, we can swap these two web sockets (JsSIP websocket and backup SBC websocket) +

+ +

Backup SBC module description and limitations

+
    +
  1. +Main and backup SBC use same account credentials (user, password, realm, domain name) +
    2. + +
  2. +BackupSBC module is not implemented complete SIP protocol. + It supports: +
      +
    • + Sending REGISTER sequence and REGISTER authentication. +
      • +
    • + Receiving INVITE and either reject it (send 486 response) + or swap main/backup transport (to answer incoming call in JsSIP stack) +
      • +
    • + Sending keep-alive CRLF ping/pong +
      • +
    +
    3. + +
  3. +In case of failure of registration on the backup SBC transport – no action item will be done beside reconnections attempts. +
    4. + +
  4. +In case of a failure on the main transport the backup websocket transport can be swapped to the main websocket transport +The phone code detecting the case (as sequence of login disconnect events) and +swap main/backup transport (if backup SBC is registered) +
    5. + +
  5. +In case of receiving an INVITE on the backup websocket transport will be called incomingInvite() callback. +The phone code check if there are open calls in main JsSIP transport. +If there exists open calls in main JsSIP transport phone will reject the call. +Otherwise it will switch main/backup transport and receive the call in main (JsSIP) transport. +
    6. + +
  6. +ACD will be supported on the main channel only. +In case of a swap we will re-subscribe to ACD service. +
    7. + +
+ + +

How phone code should be modified to use dual registration

+ +

+To understand it, see usage of "backupSBC" object in phone.js +

+ +

+

    + +
  • Creation +
    
+    let backupSBC = new BackupSBC();
+
    +
    • + +
  • Set parameters +
    
+    backupSBC.setAddresses(backupAddresses);
+    backupSBC.setLogger(backup_sbc_log);    backupSBC.setReconnectIntervals(phoneConfig.reconnectIntervalMin,phoneConfig.reconnectIntervalMax);
+    backupSBC.setKeepAlive(phoneConfig.pingInterval);
+
    +
    • + +
  • Listeners. +
    
+    backupSBC.setListeners(...);
+
    + +There are 2 listeners: +
      +
    • loginStateChanged +

      + To notify if backup SBC is connected/registered or not. +

      +
      • + +
    • incomingInvite +

      + When there is incoming in backup SBC INVITE
      + phone must decide if answer the call ( backupSBC.swap(invite) )
      + or reject it ( backupSBC.reject(invite) ) +

      +
      • +
    +
    • +
    +
  • If phone detect sequence of main SBC failures, and backup SBC is + registered it will swap main/backup SBC. +
    • +
    +
  • During page reloaded to keep currently used main and backup SBC
    + See usage of "isSwapped" variable + It set in onBeforeUnload and saved to session storage. + It used when phone starts after the page reloading. +
+

+ + +

Device selection (microphone, camera, speaker)

+ +

+It would seem that it could be easier?
+Get a list of devices (microphones, cameras, speakers).
+Choose the preferred one of each type.
+Then we use the device ID of the selected devices. +

+ +

+For input devices (microphone and camera) we use the device ID in getUserMedia constraints. + +


+     getUserMedia({audio: { deviceId: "speaker-device-id" }});
+     getUserMedia({video: { deviceId: { ideal: "camera-device-id"} }}
+     getUserMedia({audio: { deviceId: { exact: "speaker-device-id"} }}
+
+ +For output audio devices (speaker) we use audio element setSinkId() method. +

+ +However, it's really not that easy: + +
    +
  • Browser and OS implementations are different.
    + iOS does not provide output audio devices and uses system default.
    + Firefox don't enumerate output audio devices.
    + audio element setSinkId can be not implemented in some browsers - before usage + we should check if it's implemented. + +
    
+    if (audioElement.setSinkId)
+        audioElement.setSinkId(deviceId);
+
    +
    • +
    + +
  • The selected device can be disconnected. + Especially if using USB or bluetooth headset. + +If disconnected while the phone page is open, this can be detected using "devicechange" listener. +
    • +
    + +
  • Device list can be used as browser fingerprint.
    + For this reason, WebRTC API provide a complete list of devices, + only if you open getUserMedia stream (for Chrome if set the device usage permission) +
    • +
    + +
  • You can detect if the device list incomplete if device labels are empty string ("")
    + If device list is incomplete some devices can be removed (e.g. there is single camera instead rear and front cameras) +
    • +
+ +

+When we start the phone we usually don't use getUserMedia.
+(It will look strange, we are not calling anywhere, but we are already asking permission to use the microphone and camera) +

+ +

+In this case, we will get an incomplete list of devices, in which there will be no devices selected in the previous browser session.
+In our examples, in this case, we add the devices selected the previous time to the list of devices. +

+ +

+Тhis approach will work if the previously selected device is connected. +

+ +

+However, if it removed, then it all depends on what constraints we use. +If we use the ideal constraint: +

+ +

+


+    getUserMedia({audio: deviceId: { ideal: "device-label" }})
+
+In the absence of this device, the default device will be used. +

+ +

+However, if we use exact constraint and device is missed, there will be an exception: +OverconstrainedError {name: 'OverconstrainedError', message: '', constraint: 'deviceId'} +


+    getUserMedia({video: deviceId: { exact: "camera-id" } });
+
+

+ +

+We provide utils.js SelectDevices class which collects and stores a list for all available devices.
+The class used in single call, multi call phone prototype and Citrix phone. +

+

Device selection in different browsers and operating systems

+

+Browser|OS       Microphone  Camera  Speaker     Note
+
+chrome|windows   +microphone +camera +speaker 
+chrome|macos     +microphone +camera +speaker

+
+ +

Change codecs priorities. Remove codecs

+ +

+RTCRtpTransceiver.setCodecPreferences() method using to removing or changing codecs priorities.
+The method is not implemented in Firefox. +

+ +In our SDK we provide method: phone.setCodecFilter(). +
+

+Codec set as name, e.g. 'pcma' (case insensitive)
+name with frequency e.g. 'pcma/8000'
+name, optional frequency and fmtp: e.g: 'VP9/90000#profile-id=0'or 'VP9#profile-id=0' +

+ +

+ + +

Change codecs priorities

+ +

+Make PCMU, PCMA codecs more priority than OPUS. +


+    phone.setCodecFilter({ 
+        audio: { priority: ['pcmu', 'pcma'] }
+    });
+
+

+ +

+Modify video codecs priorities. +


+    phone.setCodecFilter({ 
+        video: { priority: ['av1', 'vp9', 'vp8'] }
+    });
+
+

+ +

Removing codecs

+ +

+Note: It’s not recommended! +
+It is better to keep all browser-provided codecs to ensure compatibility with different browsers and operating systems. +

+ +

+Remove ISAC and G722 audio codecs. +


+    phone.setCodecFilter({
+        audio: {
+             remove: ['isac', 'g722'],
+        }
+    });
+
+

+ + +

+All codec filters must be set once.
+Here is a more complicated example
+


+    phone.setCodecFilter({
+        audio: {
+            remove: ['isac', 'g722'],
+            priority: ['pcma', 'pcmu']
+        },
+        video: {
+            remove: ['h264', 'vp9#profile-id=2', 'av1', 'ulpfec'],
+            priority: ['vp9', 'vp8']
+        } 
+    });
+
+

+ + +

Call quality score

+A functionality has been added to Mediant SBC that evaluates the sound quality after a call is completed.
+If this option is enabled, then after the call the web client will receive out of dialog SIP NOTIFY with +customer header X-VoiceQuality which includes a voice quality.
+Take a look to phone prototype code: +

+incomingNotify: function (call, eventName, from, contentType, body, request) {
+    ac_log(`phone>>> incoming NOTIFY "${eventName}"`, call, from, contentType, body);
+    if (call === null) { // out of dialog NOTIFY
+        if (eventName === 'vq') { // voice quality event
+            let vq = getXVoiceQuality(request); // X-VoiceQuality header parser, defined in file utlis.js
+            if (vq) {
+                ac_log(`NOTIFY: "X-VoiceQuality" header: score="${vq.score}", color="${vq.color}"`);
+            }
+        }
+    }
+	. . . .
+
+Score is small integer value and corresponding color: +
    +
  • green - good quality
    • +
  • yellow - fair quality
    • +
  • red - low quality
    • +
  • gray - N/A (cannot calculate score)
    • +
+ +

Click-to-call test call

+At the request of customers, a test call was added to the click-to-call phone.
+If set testCallEnabled:true in the file config.js will be shown additional button "Test line".
+"Test call" is call to a special SBC user configured to automatically answer and send an audible prompt.
+
+To trigger Mediant SBC to evaluate the call quality to INVITE added custom Header:X-AC-Action: test-voice-quality
+To request URL added call duration (milliseconds) parameter ;duration=10000
+After the specified interval has expired, the SBS terminates the call and sends BYE +with header:X-VoiceQuality which includes a quality score. + +

Hidden page timer throttling

+

+All modern browsers use timer throttling for hidden page.
+If timers for hidden pages work with a resolution of 1 second, this is not a problem for the phone.
+We are concerned about cases when the timer works with a deviation of more than 10 seconds. +

+ +

Since Chrome 88 used intensive timer throttling
+See Chrome timer throttling
+In the mode timer resolution is 60 seconds !
+
+Safari 14 also uses intensive timer throttling for hidden page. +

+ +

+Now we have to adapt the SDK to work with such "accurate" timers. +

+ +

+It turned out that JsSIP itself does not enter to Chrome intensive timer throttling mode, unless you use REGISTER timeout for less than 65 seconds. +

+ +

+However, if you use our SDK with a websocket keep alive pings with an interval of 10..20 seconds, +the phone enters to Chrome intensive timer throttling mode. +

+

+Another way to force the phone to enter this mode is to build its GUI +based on a framework that uses timers intensively (e.g. for smooth scrolling). +

+

+JsSIP continues to periodically send REGISTER even when timer works with big delay.
+However, there is a small chance that the phone will not be registered on the SBC +for a short period of time (about 30 seconds) before sending the next REGISTER.
+

+ +

+In modified JsSIP used for the SDK, expiration interval has been changed: the REGISTER is sent a little in advance,
+taking into account a possible timer delay of 1 minute. +

+ +

+For phone developers it is recommended to catch page visibility event,
+and when it is hidden, do not use the timers during this period.
+This will prevent entering to intensive timer throttling mode. +

+

+document.addEventListener('visibilitychange', () => {
+    if (document.hidden) {
+        stopUseTimersInGUI();
+    } else {
+        startUseTimersInGUI();
+    }
+});
+
+ +

+To phone testing/debugging can be used the code that print timer deviation: +

+ +

+   {
+        let origSetTimeout = setTimeout;
+        setTimeout = (func, delay) => {
+            let key = origSetTimeout((orderTime) => {
+                let calcTime = orderTime + delay;
+                let delta = Date.now() - calcTime;
+                console.log(new Date().toISOString().slice(11, -1) + ' TIMER execute timeout key=' + key + ' delta=' + delta);
+                func()
+            },
+                delay, Date.now());
+            console.log(new Date().toISOString().slice(11, -1) + ' TIMER: setTimeout ', delay, key);
+            return key;
+        }
+        let origClearTimeout = clearTimeout;
+        clearTimeout = (key) => {
+            console.log(new Date().toISOString().slice(11, -1) + ' TIMER: clearTimeout ', key);
+            origClearTimeout(key);
+        }
+        let origSetInterval = setInterval;
+        setInterval = (func, delay) => {
+            let counter = 0;
+            let key = origSetInterval((orderTime) => {
+                counter++;
+                let calcTime = orderTime + delay * counter;
+                let delta = Date.now() - calcTime;
+                console.log(new Date().toISOString().slice(11, -1) + ' TIMER execute interval#' + counter + ' key=' + key + ' delta=' + delta);
+                func()
+            },
+                delay, Date.now());
+            console.log(new Date().toISOString().slice(11, -1) + ' TIMER: setTimeout ', delay, key);
+            return key;
+        }
+        let origClearInterval = clearInterval;
+        clearInterval = (key) => {
+            console.log(new Date().toISOString().slice(11, -1) + ' TIMER: clearInterval ', key);
+            origClearInterval(key);
+        }
+    }
+
+ +

+Can be seen that Chrome when page is hidden uses timer throttling with timer resolution 1 seconds.
+А web phone running on a laptop with a hidden page enters intensive timer throttling after 5 minutes, +with timer resolution 60 seconds. +

+ + +

SDK setWebSocketKeepAlive method

+ +

+The method code has been rewritten.
+


+setWebSocketKeepAlive(pingInterval, pongTimeout=true, timerThrottlingBestEffort=true, pongReport=0, pongDist=false)
+
+

+ +
    +
  • + pingInterval: +
      +
    • >= 0 Ping interval in seconds. E.g. 10 or 20 seconds.
      • +
    • 0 Don't send pings.
      • +
    +
    • +
  • + pongTimeout=true (default) +
      +
    • true Close and reopen websocket after pong timeout
      • +
    • false Print warning and continue
      • +
    +
    • + + +
  • + timerThrottlingBestEffort=true (default) +
      +
    • + false: Print warning if timer throttling is detected. Do not change ping interval. +
      • +
    • + true: (default) For Chrome set internally object:
      + {log: 0, chrome: {interval: 1, visibility: true, call: true, log: 1}}
      + Print warning if timer throttling is detected. Do not change ping interval. +
      + In previous SDK 1.15 used interval: 62 to increase ping interval and exit from + intensive timer throttling mode. + Now ping/pong algorithm changed (each received pong reset timer). + Phone don't enter to intensive timer throttling mode because ping/pong keep alive, + so no need increase the ping interval when the throttling is detected. + (phone can enter to the mode because used GUI framework) +
      • +
    • + Object likes: {log: 0, chrome: {interval: 1, visibility: true, call: true, log: 1}}
      + For debugging and fine tune.

      + The object {log: 0, chrome: {interval: 1, visibility: true, call: true, log: 1}} + used internally for timerThrottlingBestEffort=true

      + The object {log: 0} used internally for timerThrottlingBestEffort=false

      + Can be used other values, e.g. to print each detected timer throttling in Safari (not only 1st) set:
      + {log: 1, chrome: {interval: 1, visibility: true, call: true}}

      + + Parameters description:
      +
        +
      • + log: [integer] log level for all browsers
        +
          +
        • 0 print when changed ping interval. Detected timer throttling printed only one time.
          • +
        • 1 print when changed ping interval and each time when detected timer throttling.

        • 2 print all relative events (when changed page visibility or call started/terminated)
          • +
        • 3 print for each ping timer deviation (milliseconds)
          • +
        + Levels 2 and 3 for debugging. +
        • + +
      • + browser names and actions.
        + Can be seen that we do something only for Chrome. +
          +
        • + interval: [integer] + if this value is not 0 and is greater than the current ping interval, + increased ping interval after timer throttling is detected. + To allow Chrome exit from intensive timer throttling mode, the interval must + be more than 60 seconds + (it was actually in SDK 1.15, since SDK 1.16 improved ping/pong algorithm don’t switch Chrome + to intensive timer throttling mode. No need increases the interval to exit the mode)
          + If programmer want be compatible with SDK 1.15 setting, he can set the interval 62 seconds. +
          • +
        • + visibility: [boolean] check page visibility
          + when page is visible: use original ping interval value,

          • +
        • + call: [boolean] check if there is active call.
          + if there is active call use original ping interval value.
          +
          • +
        • + log: [integer] (optional) log level for the browser.
          + If set overload log value set for all browsers. +
          • +
        +
        • +
      +
      • +
    +
    • + + +
  • + pongReport=0 (default)
    +
      +
    • >= 0 Each n pongs print pong report with min and max delays. E.g. 50
      • +
    • 0 Don't print pong report.
      • +
    +
    • +
  • + pongDist=false (default) +
      +
    • true Add to report also pong delays distribution
      • +
    • false. Don't print pong delays distribution
      • +
    +
    • +
+ +

+Note:
+To prevents Chrome enter to intensive timer throttling mode mode, can be played a beep each 25 seconds.
+See phone_prototype: audioPlayer.playShortSound +

+ +

+Safari 14 uses different timer throttling algorithm.
+I don't found its description, but as I see added random timer delays, likes 0..50 seconds for hidden page.
+Increased timer interval does not help, because a page does not exit the timer throttling mode.
+For Firefox and Safari SDK detects big timer deviation (>10 seconds), prints warnings and does nothing.
+If timer delays less than 60 seconds, modified JsSIP registrar works without problem.
+

+ + +

+

Let's summarize the recommendations

+
    + +
  • Use REGISTER expries not less than 140 seconds (preferably 600 seconds)
    • +
  • Use websocket keep alive pings with an interval of 10..60 seconds.
    • +
  • Use timerThrottlingBestEffort=true
    • +
  • Listen visibilitychange event and for hidden page do not use timers.
    • +
  • Optionally for Chrome when page is hidden, play an almost inaudible beep sound every 25 seconds.
    • +
+

+ +

  • iOS Safari for IPhone
    • +
+

+ +

+For Chrome for Android and iOS Safari for IPhone the sound is played on bottom loudspeaker, +instead of top loudspeaker (acts as earpiece). +
+ +It cannot be reassigned, because WebRTC API does not expose the top loudspeaker as an available output device.
+(See navigator.mediaDevices.enumerateDevices())
+This problem can be solved if you connect external headset to the mobile phone. +

+ +

+

Chrome for Android limitations
+
    +
  • +The sound is played on bottom loudspeaker. +
    • +
  • +Notification API is not implemented (at least in simple form), so there is not incoming call notification.
    +
    • +
  • +Screen Sharing is not implemented.
    +
    • +
  • +Video call problem: the call works, but browser crashed after the call termination. +
    • +
+

+ +

+

iOS Safari limitations
+
    +
  • +The sound is played on bottom loudspeaker. +
    • +
  • +Notification API is not implemented, so there is not incoming call notification
    +
    • +
  • +Screen Sharing is not implemented.
    +
    • +
  • +Еvent "beforeunload" is not implemented, so after page reloading phone cannot restore call,
    +cannot rise priority of previously connected SBC and send SIP un-REGISTER +
    • +
  • +Video call problems:
    + +Video stream from the camera (local video stream) sometimes works, and sometimes it does not (shown as a black square).
    + +If you open the 2nd video call (in multi-call phone) then the video from the first one stops working (a black square is shown) +

Notes about Apple Safari for Mac

+
    +
  • Since release 1.9 SDK works with Safari 13 without webrtc adapter
    +Previous SDK releases works only with webrtc adapter
    • +
  • WebRTC can be used starting version 12 of the browser, recommended latest version 14
    • +
+

Developer's note. JavaScript console log

+

To open the JavaScript console follow the steps below:
+ In Chrome and Firefox press: Ctrl-Shift-I to open dev tools, and click to console tab.
+ In Safari press: Option(Alt)-Command-I, and click to console tab.
+ Note: should be enabled "Show develop menu in menu bar" in "Safari/Preferences/Advanced"
+

+ +

+Chrome console log settings
+To open the console: press Ctrl-Shift-I, click on the console tab.
+Click on gear icon on top:
+Disable 'Preserve log'.
+Click on 'All levels' and enable: Info, Warnings, Errors.
+To close console settings click again on gear icon. +
+
+Click on 'Customize and control DevTools' icon (above gear icon)
+Click on settings
+In 'Console' section:
+Enable 'Show timestamps' and 'Group similar'
+To close settings click on X icon at top
+

+

+About "Verbose" log level
+Using this level, problems with your certificates might be found, +violations of the JavasSript standard, misuse of Browser API, etc.
+If possible, it is worth correcting the problems found, but not all of them can be fixed.
+Therefore, this mode is recommended for debugging, but not for general use. +

+

+Firefox console log settings
+To open the console: press Ctrl-Shift-I, click on the console tab
+Disable 'Persist Logs'.
+Click on the 'Filter output' icon by the text field, Enable: Errors, Warnings, Logs and Info
+Click on the 'Filter output' icon again to close the panel.
+Click the gear icon located at the top of the console's right-hand side; +the 'Toolbox options' is seen in the in the tooltip. +Under in 'Web Console', enable 'Enable timestamp'.
+To close console: press: Ctrl-Shift-I. +

+ +

+Safari console log settings
+To open the console: press Option(Alt)-Command-I, click on the console tab
+Enable 'All'.
+
+To save console log to a file:
+

    +
  • Select a row from the console log (be sure not to highlight any text since that will change your context menu)
    • +
  • use Command + A to select all rows
    • +
  • Right click and select 'save selected'. Save the file to your computer.
    • +
+To close the console use: Option(Alt)-Command-I +

+ + +

+About 'Preserve log' or 'Persist Logs' flag
+If the flag is disabled, the console log will be cleared after page reloads.
+Generally this will be the preferred setting since it helps keep the log size to a minimum.
+
+Enable the flag when you want to see the log before and after reloading a page.
+Remember to manually clear the console logs before testing. +

+ + +

Developer's note. WebRTC adapter

+ +

+The adapter in the following link is an open source JavaScript solution.
+See webrtc adapter description
+ +The WebRTC adapter is not included in the SDK, and may be added by the developer.
+It can be downloaded from: adapter-latest.js
+

+ +

+Since SDK 1.9 we stopped using obsolete WebRTC API:
+- event "addStream"
+- RTCConnection getLocalStreams()
+- RTCConnection getRemoteStreams()
+
+The methods are not implemented in Safari 13, and added by webrtc adapter.
+Тherefore, our previous SDK releases do not work with Safari without webrtc adapter. +

+ +

+Now webrtc adapter usage is optional for all supported browsers.
+As you can see we do not use it in our phone examples.
+

+ +

Developer's note. Debugging JavaScript code

+

Let's use our 'check for available devices' example.
+In chrome open dev tools, and select sources.
+Select file phone.js
+Set breakpoint in line 48. (by clicking in the line's number)
+Reload page. Now JavaScript execution will break in line 48

+Press the 'step over next function call' serveral times in the debugger

+Check the value of some variables, then resume script execution.

+The same can be done in Mozilla's Firefox browser.
+These types of tips and knowledge can assist you in phone debugging.

+When you updating the phone's code on a website,
+you should clear browser cache and reload (in Chrome/Firefox press: Ctrl+F5)

+ +

Developer's note. Chrome local overrides

+

This option can aid you with general convenience in some tasks.
+e.g. You're interested in taking one of the examples from our website and change some of +its lines of code.
+ +

Without local overrides, you would have to create your own site, copy this example to it, +and change something in it.

+ +

Using local overrides you can accomplish this using an example from our site, and the changes +you've made are locally made to your Chrome browser with the help of Chrome's local overrides.
+To know more about how they're used, please see: local overrides +

+ +

Developer's note. About STUN protocol

+

For WebRTC - STUN protocol is critical and WebRTC cannot work without it.

+

The STUN protocol is usable when your client is connected to a network using NAT.
+In a case when the client communicates with an external internet, +NAT convert its IP and port to another IP and port so the client can't know how it is seen +from external internet (which IP and port)
+To check it, the client sends a request to a STUN server.
+The STUN server will send a response where it will write which IP and port was used in request.

+

Before establishing a connection, the WebRTC client must create an SDP offer that include all posssible phone connections IPs and ports +prepared by ICE Gathering.
+It takes all the IP available on the computer,then sends STUN requests to STUN and TURN servers +(STUN and TURN are optional and can be specified in the configuration).

+

For a WebRTC phone, you may use Google's STUN server: stun.l.google.com:19302 (Pay attention to the DNS as it returns more than one IP)
+Note: Mediant SBC works without STUN servers.
+Note: It is not recommended to use free Google STUN server for production.
+No one guarantees that it will work, so use it only for testing. +

+

If a corporative firewall disables the STUN protocol, the browser cannot receive responses +from the STUN server.

+

You can see ICE gathring using the Wireshark sniffer with the filter 'stun', as the browser sends STUN requests, + and does not receive responses.

+

+Let's use this test, to see how long it takes in your browser

+

+In the simple case, when the computer has one IP and STUN protocol is allowed in firewall, it takes less than a second. +

+

+However, consider another case: the computer has two IPs: one from a home Internet provider, +and the other is VPN of our company. +Suppose our organization's farevall is blocking the STUN protocol.
+During ICE gathering phone will send STUN requests from all available IPs.
+In this case, ICE gathering will take 40 seconds for the Chrome browser, +because during VPN IP checking, the browser will try to connect to the STUN server again and again.
+Therefore, we should set ICE gathering timeout to meet some reasonable time (a few seconds). +

+ +

WebRTC also uses the STUN protocol for other purposes such as:
+ checking if the media session is alive. +

+

A WebRTC client sends an RTP stream to the SBC server IP and port.
+It will periodically send STUN requests to SBC with the same IP and port used for the open RTP session.
+If during the call the request is not responded to, +the client will decide that the media connection has been lost.
+

+On the firewall, you’ll have to allow inbound STUN requests for your SBC server +as well with a UDP port range (the same port range that the SBC uses for RTP sessions) +

+

+If your firewall allows STUN for the STUN server, +but not for the SBC, your phone will open a connection, +work for some time (tens of seconds) and then the call will close. +

+ + +

Developer's note. Bypassing the corporate firewall

+

+The following is most important when a WebRTC phone is hosted in an organization’s intranet (private IP network), +and the SBC is hosted in the internet (e.g. Amazon’s Cloud services). +

+

The organization's firewall and NAT between the local network and the internet can cause problems in this type of set-up

+

 

+
    +
  1. SIP communication between browser and SBC: +

    SBC receives a SIP connection in a secure websocket, using port 443.
    It's the default secure websocket port that is also used for HTTPS so the port is enabled in most firewalls.

    +
    2. +
  2. STUN communication between a browser and the STUN server:
    +Note: this STUN communication is optional. To disable it, set empty values for ICE server lists in the phone’s configuration. +

    +

    Before starting an outgoing call or answering an incoming one, WebRTC runs ICE gathering (to check computer IPs)
    The browser will send a STUN binding request to the STUN server.
    We use google open STUN server: stun.l.google.com

    +

    The firewall must allow STUN communication between the browser and the external STUN server.

    +
    3. +
  3. STUN and DTLS-SRTP communication between the browser and the SBC:
    +

    Before starting an RTP transmission, the browser checks the future RTP channel:
    + It sends a STUN binding request to the SBC using the same ports it will use for RTP.
    + If the SBC responds with a STUN response, the browser starts sending RTP packets. + After the communication is established, the browser periodically sends STUN requests to check if the RTP channel is alive, + so the firewall must allow STUN and RTP communication between your browser and SBC

    +
    4. +
+

 

+

For RTP communication the browser uses WebRTC API's UDP ports.

+

As this can be an issue, we'll expand on it below.
+

+

WebRTC API designers don't provide an API to set RTP port range !

+

+To use WebRTC phone you must ask your IT security enable inbound RTP/STUN protocols for all UDP ports. +

+

If using Chrome for business, you can set the port range by Chrome corporative policy.
+(see WebRtcUdpPortRange) +

+ +

Developer's note. Setting speaker and microphone in Windows

+

+In order for the phone to work, you must properly configure the microphone and speaker for the browser. +

+

Check speaker

+

+Open the site: youtube.com and try to listen to any song.
+If you hear it, your speaker is OK.
+Otherwise open the Windows "Control Panel", select "Manage Audio Devices", +click the "Playback" tab and there you will be able to select the default device for playback. +Now repeat the "youtube" test. +

+

Check microphone

+

+Open the Windows "Control Panel", select "Manage Audio Devices", +click on the "Recording" tab and select default device.
+Say something into the microphone and and watch the green bar for activity. +

+

+You can also select a microphone internally when using Chrome as your browser. +
+Call someone and after the call is established, +click the 'camera' icon in browser address line, then +select proper microphone and camera devices for future usage. +

+ + +

About the JsSIP library used in this project

+

+HTML 5 WebRTC API supports audio and video encoding/decoding, SRTP, and SDP, +but misses the SIP protocol.
+"JsSIP" is an open source JavaScript library that provides SIP via a websocket protocol.
+It internally uses the WebRTC API, and is intended to build JavaScript WebRTC phones. +
