SIP dialin to conference ends with "Initialising Call…"

Install & Config
#1

We have a setup with SIP dialin into Jitsi Meet conferences with Jigasi. This worked in the past. I think as of jitsi-meet 2.0.7416 from 2022-06-16 this fails. It may be releated to an update. But it’s not sure.

Scenario

The participant calls the phone number, enters the PIN and enters the conference room.
In the conference, the label “Initialising Call…” is shown, the participant heres the ringing tone.

After about 15 seconds, the participant disconnects.

Logfiles

There is one entry in the Jigasi log, which is suspicious.

I have no idea, where to debug the problem. Mabe you could give me a hint?

Setup

That is strange, we haven’t seen that with latest one … Ooo, that can be a bug … need to check the code. My guess is that if you enable muted support in jigasi it will work.

#5
#6

Ahh. Stupid question: How do I enable muted support in jigasi?

#7 
org.jitsi.jigasi.ENABLE_SIP_STARTMUTED=true

Can you please open an issue in the jigasi github tracker so we don’t forget about it, I’ll be away from the PC for a few days, but when I’m back I will work on a fix. Thank you.

#8

With this setting, the SIP participant joins the conference as expected. But he is now muted of course and I didn’t find a way to unmute him. But this might be Asterisk not understanding the message?

But better than before and I will write the issue tomorrow.

Have a nice time off.

#9

Yep, it needs a some ivr managing ang getting some sip info messages.

#10

There are some examples here, but it is not trivial moving this to asterisk, but gives mute/unmute option for dial in participants
