If you can't do P2P, you can have an SFU forwarding the call with more features than a "dumb" TURN relay.

And it would just be STUN between each participant and the SFU deployed in the internal network for example.



Nice suggestion, we do this for certain deployments. Amazing what magic you can do in Janus, etc, :)


Why even need STUN, the SFU can join as a WebRTC participant, right? Node.js maybe


STUN is only useful if you're trying to negotiate a P2P connection, which isn't the case when using an SFU. If everything you're doing is going through an SFU then you don't need STUN.
