Requirements:
- multi person voice chat with all the standards (PTT, etc)
- extremely low latency because it’s self hosted, so three people in the same city should have <30ms
- easily hosted via docker compose
- FOSS optional but preferred
Mumble or Teamspeak. I run TS, myself.
Be prepared to argue with people about how they don’t hear the difference in audio quality between TeamSpeak and Discord. Take it from me, TeamSpeak wins hands-down.
This isn’t really an answer, but I spent a lot of time trying different voice chat systems out a couple years back, but couldn’t get my social group to move off Discord.
So, the real answer is any that you can convince the people you want to talk with to use. However other options include Mattermost, Jitsi, Mumble, Teamspeak, and Nextcloud Talk off the top of my head. I think I remember seeing that rocket.chat has voice now too.
Is Revolt an option, maybe?
Clearly Mumble. No need even for Docker, it comes packaged with most distros.
How about jitsi? https://github.com/jitsi/docker-jitsi-meet I am running it for years, works much better than Facebook Messenger that is for sure 😃 not sure what you mean about the “all the standards”
