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?

I ran mumble for years, insanely easy setup.
I found out the other day that I had a mumble server still running that I had been tinkering with a year or so ago and just forgot about. Hadn’t noticed it was still running this whole time because it’s so low in resource usage
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.
I have a Jitsi server hosted through a docker container that was pretty easy, and ties into Rocket Chat. Jitsi does voice and video, Rocket Chat does chat.
This has big XKCD Energy. It almost feels like an exact recreation of the comic but with tech:
I meant the OP more as a lament about it being hard rather than a quip about it being easy.
Though upon reflection it’s not the voice chat that’s a problem, it’s the fact that Discord is a lot of things, a chatroom, a VOIP service, and so on, and recreating all those things on top bolting on federation (which I don’t see as a desirable feature in this case) is what makes it so hard.
Update: I got Mumble working without a lot of grief. Their mobile client isn’t great though. I might try Stoat.
Federation just complicates things, as it’s just for a myself and a few friends.
I remember using mumble in a time when smartphones weren’t even a thing yet. Love to see the open source tool outlive everything else!
Look at fluxer it’s stoat developed by someone who isn’t retarded. Has done more in a fraction of the time and actually has functional features
Stoat is the epitome of grief lol
https://f-droid.org/packages/se.lublin.mumla is not so bad as a mobile client for Mumble.
I’m sure it is but I have an iphone
Oof. There’s an entire fdroid ecosystem you’ve cut yourself off from.
fdroidSideloadingAlmost everything in fdroid can simply be sideloaded. Due to the inability to backup your app list from fdroid, I’ve completely switched to obtainium.
iPhone has better accessibility.
Simple 1:1 audio stream is easy.
Groups, screen sharing, noise canceling, NAT traversal, mobile apps, and all those extra features people have come to expect are hard.
Exactly!
people act entitled as if all that you mention was trivial and that somehow FOSS devs “owe” people, but we only see those big corpos make it happen because… well, they’re big corpos, burning VC money on makint it happen and making it happen in a controlled jail.
I have honestly not seen anyone acting like they are “owed” these things by FOSS developers. We just want them.
I have seen lots of people. Mostly not here, but that’s because we here know better (I’d hope). Runs along with usual complaints such that they can’t move from a platform with 9trillion captive users to a new budding platform, conveniently forgetting that when they began Shitter and stuff also had like 0 users yet people did move.
As for “why is it hard to self-host”, it is only NAT traversal.
TURN, STUN, ICE, etc. are not fun to debug. Not sure if anyone still bothers fiddling with TOS/DSCP on their router. You can build a voice server that just exposes a TCP port, but… latency. And corporate firewalls love to randomly block some UDP port ranges but not others.
Mumble will do all of that except screen sharing. Only the server has to deal with NAT.
The one point that has basically been solved is NAT traversal. Thanks to Wire guard, Tailscale and the like. The relevant parts are open source and can be used basically as a library.
Groups: just simple Chanels are fine, password lock them if you want.
Screen sharing: one at a time should be fine. Self hoster can configure max bit rates.
Mobile apps: building your app to be multiplatform is a lot easier than it was a decade ago.
It’s not! Use SonoBus; it’s dead simple, and superior to Discord. It’s far lower latency, with customizable filters, peer-to-peer; and totally free.
Now if you want emojis and video and rambling channels and stuff, you will have to go elsewhere.
Sonobus
What a clever name!
It’s easy. Mumble. Or the thing you used probably still works.
But you see, people never actually seek a discord alternative. They want a discord alternative that includes all the features in one app that is also federated, AND end to end encrypted, and each one makes things vastly more technically challenging and resource intensive and then you want them together.
A little secret: Matrix is much, much easier to host if you disable encryption and federation. Federation to many servers is the main performance killer, and “failed to decrypt message” will all disappear if you disable encryption.
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’ll 3rd mumble. Been hosting for over a decade.
No tracking, no ads, no bloat… This does it’s one thing and does it very well.
Tried mumble, worked easy and well, but i realised im not able to do without persistent chat and screen share any more. Now trying to get Matrix to work.
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.
Use mumble
Don’t forget about teamspeak!
If you go with anything using livekit (stoat/revolt , lasuite meet), voice is not very hard per se (just a bunch of udp ports required).
It’s video that will get your CPU to its knees
I just can’t get over the name change from Revolt to Stoat, but at least a stoat is cute AF.
Cease and desisted, but yeah it’s sad (and annoying code-wise because you have to rename everything)
Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:

Good bot
Isn’t TeamSpeak still a thing?
Not FOSS or open source in any sense. You could still say it’s self-hosted, but I suspect most people self-hosting care about this.
Yeah, from what I understand, standing up a Teamspeak server is pretty straightforward.
I think they just announced a big new version just in time for Discord to tell us all to fuck off
I thought it was only voice though. Not screen share or chat.
Yeah, it has chat. Nothing too fancy, at least not back when I last used it (which, granted, is decades ago) but chat it has.
Good to know!
It does have screen sharing now! The Linux client currently can’t share system audio, but I think they’re working on that
Oh sweet.
So as mentioned we have both Mumble and Team Speak if you are looking for a self hosted VC.
