Hello! I faced the issue that call drops after 33 seconds due to lack of audio RTP activity.
I call from 1153(WebRTC, JsSIP) to 1154(Mobile, Linphone) extension:
1.No Audio
2.Call Drops
but workable on Linphone(Desktop) to Linphone(Mobile)
I have been checking:
1.NAT Configuration
2.Network Firewall Configuration
I have reached the end of my tether, could someone tell me where do any wrong, here’s my log:

Thank you for any help you can offer.
Use “rtp set debug on” at the CLI and see in which direction and on which legs (four in total) the RTP is missing.
Also, please use logging obtained from Asterisk itself (verbose level 5 and the appropriate protocol logging option for your channel driver. Please say which channel driver that is.
The channel driver configuration is also likely to be needed, as most such problems are the result of errors in that.
Unfortunately, WebRTC and therefore ICE go beyond my experience, so I may nto be able to provide much help on the RTP port negotiation.
Thanks for your reply.

Either RTP debugging didn’t take or you aren’t receiving any from either side.
You didn’t do pjsip set logger on
Sorry for my mistakes.
I changed the docker image from ’ tiredofit/freepbx’ to ’ izdock/izpbx-asterisk’
It worked fine on WebRTC client(Desktop) to SIP Client(Linphone-Android)
but not on WebRTC client(Desktop) to WebRTC client(Mobile)
https://pastebin.freepbx.org/view/73f7987a
I still try to find out what going on.
I fixed my WebRTC client and it worked now.
That is due to RTCPeerConnection.getLocalStreams was deprecated, and not supported from iOS client.

Thank you.
