Colp (jcolp) 2021-09-15 07:24:06.977-0500 Just like the other issue, please attach the respective logs so it can be tested when the underlying issue is looked into. By: Michael Auracher (MichaelAUM) 2021-09-15 07:24:48.260-0500 Attached log and network catpure: novideo* -> Asterisk 18.6.0 built without patch ( will show no video) patched* -> Asterisk 18.6.0 built with patch ( video is working again) By: Martin Oberhuber (mober) 2021-10-04 12:00:42.403-0500 Hello, I'm surprised that this issue is unassigned and considered low priority? It is apparently a regression compared to Asterisk-16.9 And it affects all devices that receive only video but don't send any. After upgrading to Asterisk >= 16.10 , those devices do not receive any video any more, if they are the caller !! Is there anything we can do to help investigation or development ? Reverting the res_pjsip_session.c changes from the description fixes the problem. But we don't know what side-effects reverting those changes has. And what that change was good for in the first place. Can you explain? Thanks! Martin By: Joshua C. Colp (jcolp) 2021-10-04 12:04:20.244-0500 If any additional information is required or needed, it will be commented here and once someone is looking at this then it will be assigned. From a Sangoma perspective it is in the queue to be looked at, I have no time frame on when that will happen. I can't speak for the community at large as to whether any individual has any interest in this.
