I remember discussing this topic some years ago when jitsi (desktop at the time) only had support for ICE in xmpp but not in SIP. Not sure how it evolved over the years.
I’m having some occasional 1 way audio problems when trying to dial out through jitsi-meet (using jigasi with an account registered on the open source flexisip SIP server), and I believe it’s due to ICE not working.
What’s the current status of ICE in jigasi? How can I enable it?
