This has been done with Mumble, it just needs some refinement. Mumble (the client) and Murmur (the server) [1] [2] can handle many people on a small server. I have run a murmur server for a long time and it is very stable. The voice quality is superior to anything else I have used. The client does need a little bit of refinement to be as happy-clicky easy as Discord. If anyone has not tried version 1.3 [3], give it a go. There are public servers if you want to try the client without hosting your own server. Their code is all on Github and I am sure they could offer suggestions if you were using their libraries in your application.
