Hello there!
I am trying to create a conference feature in our webRTC based softphone. I believe I have the proper audio mixing on the client end, but when I renegotiate, I see an Rx buffer overflow error:
[Dec 9 22:35:32] ERROR[23244]: pjproject: <?>: sip_endpoint.c Error processing packet from 127.0.0.1:48930: Rx buffer overflow (PJSIP_ERXOVERFLOW) [code 171062]:

I found this stack overflow article with the same issue: https://stackoverflow.com/questions/39275328/asterisk-13-10-pjsip-webrtc-rx-buffer-overflow-pjsip-erxoverflow
The problem with this solution is we do not build asterisk or pjsip from source, so we can not overwrite the constants that the selected answer suggests.
My question is there another way to get around this or should I just find some way of using the ConfBridge application instead?
