Hi @Blancduman ,

Do you have any idea for this?

Hello. You need permission to work in background.

we have configured project to support ios background modes for android you need permission to run foreground service but how to achieve running mediasoup when app is in background screen has been turned off and event when app is terminated.

<key>UIBackgroundModes</key>
	<array>
		<string>audio</string>
		<string>fetch</string>
		<string>remote-notification</string>
		<string>voip</string>
	</array>

in our to properly support push to talk you need to integrate IOS Native Push To Talk framework.
https://developer.apple.com/documentation/pushtotalk/creating_a_push_to_talk_app

we manage to play in the background, wake app from suspended state and even from terminated state.
The only issue is that this framework handles Audio Session and there is option to disable audio session handling for flutter_webrtc plugin.
