Are you interested only in Jitsi Meet instances?

If more generally interested in Open standards and Free licensed 
instances, I can recommend to also try locate services using 
SylkServer/Janus/Mediasoup/Licode/Medooze/Spreed/BigBlueButton/OpenMeetings, 
and identify at each _service_ which underlying engine/framework is used 
to aid in reliability issues.

Concretely it seems Jiti Meet works reliably only when _all_ 
participants in a room use a Chromium-based web browser: 
https://github.com/jitsi/jitsi-meet/issues/475

My guess is that Jitsi Meet fails to parse SDP data in the 
standards-compliant "unified" format and only properly handles "plan B" 
style as used by Chromium-based browsers.  And my guess is that other 
engines/frameworks perform differently at that.  I am unaware that 
anyone has tested for this type of problem.

Matrix instances use Jitsi Meet.

NextCloud instances use Spreed.

https://sip2sip.info/ uses SylkServer.

https://letsmeet.no/ uses Mediasoup.
