App s Microphone does not work when Push to Talk channel is joined. I m trying to use App s Microphone Button to record the audio. With new beta seems not working.

Trying to use PushToTalk UI while application is in foreground. It was working with older Beta 3 version. Please suggest what needs to be done.

When App is in background , it is suspended. And PushToTalk is shown in Status bar. When user click s on that, Application gets CPU. Which callback is called when PushToTalk on status bar is clicked.
