Conference BYE for participant after some time

Asterisk Asterisk WebRTC
1

I’m working on a client for Asterisk conference. Calling in works. Video is started fine. I can see other participants joining, but after a couple of seconds each participant receives a BYE and is kicked out. Before, I got another issue that indicated that it has to do with an invalid OPTIONS response(had to do with an invalid branch), but I can’t seem to find the issue here. A correct OPTIONS response with another SIP client, which keeps the call session alive:

Asterisk console just notices a leave:

asterisk    |     -- Channel PJSIP/2000-00000015 left 'softmix' base-bridge <fb23d0af-aafa-4a61-b470-2b451cdd8022>
asterisk    |     -- <CBAnn/guest-0000000c;1> Playing 'confbridge-leave.slin' (language 'en')
asterisk    |     -- Channel CBAnn/guest-0000000c;2 left 'softmix' base-bridge <fb23d0af-aafa-4a61-b470-2b451cdd8022>

Any idea what I’m missing in the SIP Response, that causes the call to end?

2

An OPTIONS request wouldn’t cause a BYE. You’d need to show a full SIP trace as to what is going on.

Hi @jcolp, thanks for the help! The issue reminded me of Contact reachable/unreachable, which was related to an invalid OPTIONS response(invalid branch parameter). That’s why I thought these disconnects might have to do with it. The full trace:

Is this a full SIP trace? I don’t see any responses to the MESSAGE requests which would be problematic. If the Javascript doesn’t support them then you’d want to disable the sending of events.

Hey @jcolp. Thanks for pointing me in the right direction! I totally disregarded MESSAGE requests. Settings enable_events=no in the bridge fixed the issue for now. I’ll look into what’s wrong with the message response I’m using.

Turned out that I messed up the dialog info. The conference is now kept alive with enable_events=yes
