Conversations -> JSXC call not connecting?

[Tuxicoman2]

Expected behavior

I expect to call from Conversations to JSXC using audio call

Actual behavior

JSXC receives the call and ask to accept it. I do.
Then JSXC and Conversations are stuck in the process and the audio never start.
Conversations tells "Connection in progress"

If I do the other way around, I call from JSXC to Conversations using audio call. it works fine.

Steps to reproduce the behavior

I call from Conversations to JSXC using audio call
I tested from a laptop with webcam and a desktop without webcam. The beahvior is the same.
The XMPP/Web server and devices are on the same LAN.

Environment

• rev 8ad6882 at 19 january 2021

Works fine on Chromium 83

[Tuxicoman2]

But doesn't work on Firefox 84 :-(

[sualko]

If you are connected will multiple clients Conversation will use XEP-0353: Jingle Message Initiation which is currently not supported, see #890. Is this the case for you?

[Tuxicoman2]

Maybe that was because I closed a web tab where I had JSXC running a few seconds before and Conversations didn't notice it.

I tried again using a browser where I just open a single JSXC, (no other opening since hours before), and I reproduce the same behavior. What debug info could I produce more or where should I debug do go forward in your opinion?

Best regards,

it seems to be a firefox problem, movim xmpp client has the same symptoms
