Hello developers,
Recently we experienced a network issue which made the WebRTC server unreachable, the Android clients crashed instead of outputting an error.
I have two different crashlogs of the crashes:
The first:
java.lang.NullPointerException: Attempt to invoke virtual method 'void java.util.Timer.cancel()' on a null object reference

Hopefully the team will fix the crash and let the call end gracefully, thanks in advance!

sorry, currently setting sample rate for audio codec isn't supported yet.

I got it. So If I want using low sample rate, I have to switch audio codec to PCMU or ISAC
