iOS Audio not working during call answered when phone is locked. WebRTC used for calling

Question

I am facing a problem with Audio When using Callkit with WebRTC for VOIP call, While answering the call from Lock Screen.

General Functionality :

Answer 1

I am able to resolve this issue.

Steps that I followed -

• I checked the code related to WebRTC here

• I added RTCAudioSession header file which is actually a private class of Webrtc. So every time I receive a call event from signaling, I enable RTCAudiosession and on end of the call, I disable it.

• I have to render the incoming streams to a dummy view (Although it is not displayed when the call is going and the app is not yet open, but it is required to make audio working).

I hope this will help if someone is facing the same issue.
