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?
Not a good discord replacement but setting up nextcloud talk (simple p2p voice chat) and then the high performance backend (better supports video/voice calls between 3+ people) was relatively easy. We use it among my family now to have group calls instead of relying on facebook messenger.
