Problem with the plug-in for voice calls and screen sharing

Troubleshooting
23

This is very strange, because for the experiment, the windows firewall and antivirus were disabled at that time. And this is not a single computer problem. The same thing happens on three different devices.

Hi,

I also have the exact same problem, only 1 way voice is working and its always on the caller no matter on what device, the caller voice will always working fine, but callee can not.
Caller ➜ Callee = Audio OK
Callee ➜ Caller = No Audio

I even test with a coturn server to make sure the peer to peer connection on NAT/ISP strict works.

and from the logs i can see this :
Incoming unhandled RTP ssrc(…), OnTrack will not be fired. mid RTP Extensions required for Simulcast
Could not determine PayloadType for SSRC …

from chatgpt show me that the problem is "

  • the calls plugin does not receive RTP MID extension,
  • OnTrack() WebRTC is not called
  • RTP stream is not decoded, so the callee can not hear anything.

please help.

Thanks

Hi,

After spending all night I finally found the root cause of this.
On the log i see this error :

Incoming unhandled RTP ssrc(…), OnTrack will not be fired. mid RTP Extensions required for Simulcast

on my case, this happen when I activate this menu “Enable simulcast for screen sharing (Experimental)” from System Console → Calls

now voice is working both ways.

hope it can help the others.

Thanks
