All this talk about Discord replacements plus my own experience attempting to host a Synapse has got me wondering why it seems so hard to implement voice chat.
Stupid idea: back in 2022 I got an Asterisk server working on a raspberry pi over AREDN without too much trouble. What’s stopping people from just using a PBX like that for voice chat?
Try mumble if you just need voice. Just fire up a docker container and open a tcp and a udp port. The settings are under-documented so things like auth are tough to set up.
I second mumble, it’s a 5 min job to fire it up and default servers settings are enough to get going out of the box.
