Matrix voice and video chat is sadly under-equipped for the only kind of thing I want (team gaming and screen share). They are working on moving to a new realtime media transport but until it manifests I can’t see it as an alternative. I’ve read about Revolt and some others but I don’t see anything that seems capable. Happy to be corrected on this!

EDIT: it looks like Element Call is more or less ready, might try setting up a server this weekend.
