TLDR: The r/selfhosted subreddit has a Discord server. The owner’s account got hacked leaving the server in a precarious state. They submitted a support ticket, but Discord has not taken action in weeks and probably won’t at all, so they are considering starting a new Discord server.
So the matrix protocol doesnt have voice like I thought.
Yes, it does. Like I have said, that part of the protocol is called MatrixRTC. It is not a hack, or a mod, or third party.
