Asterisk::AJAM

---

This is a very simple library that allows to comunicate with Asterisk PBX using Asterisk Management Interface (AMI) actions. Library communicates with AMI through HTTP(s) protocol. HTTP interface is provided by Asterisk PBX and called AJAM

This library does not provide events interface to AMI. It only sends actions/commands and read responses back. If you need real AMI interface please, check Adhearsion framework which is very powerful and provides a lot of functionality.

This library can use HTTTP Authentication username/password for AJAM servers behind proxy protected with basic access authentication scheme and HTTPS (SSL).

Installation

Add this line to your application's Gemfile:

gem 'asterisk-ajam'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install asterisk-ajam

Usage

You can check file example/ajam.rb for some examples (comes with source).

Simple example:

require 'asterisk/ajam'
ajam = Asterisk::AJAM.connect :uri => 'http://127.0.0.1:8088/mxml',
                              :ami_user => 'admin',
                              :ami_password => 'passw0rd'
if ajam.connected?
	ajam.command 'dialplan reload'
    res = ajam.action_sippeers
    res.list.each {|peer| puts peer['objectname']}
end

List of argument options for Asterisk::AJAM.connect:

• :uri URI of AJAM server. See Asterisk documentation which explains how to configure AJAM server.
• :ami_user AMI user username
• :ami_password AMI user password
• :proxy_user proxy username for HTTP Authentication
• :proxy_pass proxy password for HTTP Authentication

If URI scheme is "https" then library enables SSL use. Please, note that current version does not enable verify mode of Net::HTTPS ruby library so it will accept any SSL certiificates without verifications.

Asterisk::AJAM.connect returns Asterisk::AJAM::Session class which provides several useful methods:

connected? returns true if successfully logged in AMI

command send command to AMI and read response. Example:

ajam.command "dialplan reload"
ajam.command "core restart when convenient"

action_NAME sends action to AMI. NAME must be replaced with AMI action name (see: Asterisk documentation). Accepts hash as an argument. Example:

ajam.action_agents # no arguments
ajam.action_mailboxcount mailbox: "5555@default"
ajam.action_originate :channel => 'Local/local-chan@from-pstn',
    				  :application => 'MusicOnHold',
    				  :callerid => 'John Doe <5555555>'

Actions and Commands return Asterisk::AJAM::Response class with several methods where response data can be found:

• list
• attribute
• data

res = ajam.action_meetmelist
pp res.list
pp res.attribute
pp res.data

Using Apache proxy tutorial

As an additional security measure Apache proxy with HTTP Authentication can be used. Here is an example of Apache Virtual Host configuration as Proxy to AJAM server

Listen 8888
NameVirtualHost *:8888
<VirtualHost *:8888>
  <Proxy *>
    Order deny,allow
    Allow from all
    AuthName "AJAM"
    AuthType Basic
    AuthUserFile /etc/httpd/.htpasswd
    require valid-user
  </Proxy>
  ProxyPass / http://ajamhost.com:8088/
  ProxyPassReverse / http://ajamhost.com:8088/
</VirtualHost>

Generate password file:

htpasswd -b -c /etc/httpd/.htpasswd admin passw0rd

Connect to proxy:

ajam = Asterisk::AJAM.connect :uri => 'http://ajamproxy.com:8888/mxml',
                              :ami_user => 'admin',
                              :ami_password => 'amp111',
                              :proxy_user => 'admin',
                              :proxy_pass => 'passw0rd'
