mediasoup-demo VS Mumble

Do check out the mediasoup demo as an example (https://github.com/versatica/mediasoup-demo). There is an online demo here as well (https://v3demo.mediasoup.org/)

There is already a Dockerfile for the server. The problem is that the mediasoup config file doesn't currently work inside docker so it needs to be updated. Mediasoup has created a demo of how to make it work inside docker here.

the strange thing is that this Docker image runs with audio just fine:https://github.com/versatica/mediasoup-demo . I should have included that information in the OP. I'm trying to see how the Dockerfiles materially differ as it relates to ports, but I don't see it. The file also doesn't need to be run in host network mode

While I'm building this https://github.com/versatica/mediasoup-demofor >400 seconds, docker desktop on macos crashes with this error level=error msg="Handler for GET /system/df returned error: error getting build cache usage: failed to get usage for h23kzrlo9o1ntzqg8djaak2ql: snapshot 6p6vktbybxdisl2r4iovhkxaf not found I feel like this should not be happening due to resource limits since I have big sur on a 2018 macbook pro, a core i7 and 32 gb of ram. I've tried 4 times consecutively of building and restarting docker desktop before giving up. Thank you.

I think Sonobus is overkill. I suggest you look at a couple of relatively old-school gamer voice chat tools - Mumble or Teamspeak. Mumble is open-source and the connection is always encrypted, Teamspeak is commercial but the free tier should be fine for you - but you have to make sure to manually turn encryption on yourself. It has been a long time since I used either, so I don't know which is easier. Both of them require you to run their matching server software.

Mumble's latency is unbeatable imo, it's basically their main focus and shows.

The sticking point for me is the lack of persistent messages, something the devs strangely think is a privacy plus. Issue open since 2016: https://github.com/mumble-voip/mumble/issues/2560

If you drop out for a minute you won't have access to anything that was posted in chat, which makes it useless for anything other than voice only comms, that might suit some business purposes but I've always needed to post links or screenshots in chat during meetings.

There's any number of alternative chat applications available, like Element, Mumble, Teamspeak etc.

Mumble?

I think Mumble might fit what you're looking for. It's been a very long time since I've used it, but it seems to still exist: https://www.mumble.info/ - I've used previously for exactly what you're describing, events with lots of crew dispersed around and no budget for radios. I had it installed on an AP running OpenWRT so it was just a case of plugging that in and getting people to install the app and connect to it.

Along with the options already mentioned, if you're not into TeamSpeak, there is an open source alternative called Mumble which operates in the same manner. No internet required, and is supported on multiple platforms.
