[IOS] Audio sometimes doesn't work when used with WebRTC connection

HI.

I'm building an app and have some issue.
Here is my scenario.

// Establish WebRTC Connection
InCallManager.start({ media: 'video', auto: true });
// Communicate through RTC Connection

// After all communications done
InCallManager.stop();

// Re-establish WebRTC Connection 
InCallManager.start({ media: 'video', auto: true });

Here is problem.
When I re-establish the connection and start InCallManager again, the Audio doesn't works at all,
i.e. Mic input and Speaker output.

My assumption is due to IOS AVAudioSession, because WebRTC assumes that it's the only one controls AVAudioSession which is implemented as a singleton.

Am I right? and how can I fix it? (or do you have any plan for fixing it?)

React-Native-IncallManager Version : v3.3.0
libWebRTC : M84

Start by reproducing the second InCallManager.start({ media: 'video', auto: true }) call after InCallManager.stop(), focusing on the AVAudioSession and WebRTC interaction described in the issue. Compare microphone input and speaker output across the first and re-established connections; done means audio works after the restart.
