mumble is pretty good. I’ve been using it for a few years, has great client server support, no bullshit on either side of the fence there. Super minimal client, though my linux client has issues with leaking memory, easy enough fix though, kill it and restart, which takes 2 seconds.

has pretty good bot support, you really can’t ask for much more, a bit more support and community utilization would be nice though, it’s somewhat dead.

So far mumble has been the definition of “just works”
