As the creator of Calla, I would say that there is not much to be learned from Calla specifically.
The WebRTC portion was all implemented through Jitsi Meet, and I eventually grew to regret that direction. My current work uses just a CoTURN instance with a fully custom backend for managing multiplayer.
The user interface was only ever intended to be a demo, I didn't have any interest in running it as a FOSS project in its own right, and it while I would say it was certainly a competent implementation, it also wasn't anything ground-breaking in any way.
That basically leaves just the core audio graph management as anything that was valuable in the project. That part still lives on in my project at work, but considering I basically gave up on trying to run FOSS projects after some deep introspection on my experiences with running FOSS projects, I don't put much effort into documenting my code anymore. But if you want to see the audio graph management stuff, the latest version is here: https://github.com/capnmidnight/Juniper/tree/master/src/Juni....

The WebRTC system that I now use is largely this on the client (https://github.com/capnmidnight/Juniper/blob/master/src/Juni...) plus this on the server (https://github.com/capnmidnight/Juniper/tree/master/src/Juni..., which is a SignalR hub in an ASP.NET Core app, but should make the signaling flow clear). And then this code uses the client (https://github.com/capnmidnight/Juniper/blob/master/src/Juni...)
