The default installs of Jitsi Meet use Jitsi videobridge to avoid p2p for calls of >2 participants. For <=2 people, p2p WebRTC is used (though a STUN server might be needed to traverse NATs for each person [0]). For >2 people, the Jitsi Videobridge is used instead of p2p [1]: it takes in all media streams from all clients (possibly even in different resolutions) and selectively forwards them to clients based on bandwidth [2] [0]: https://en.wikipedia.org/wiki/STUN https://en.wikipedia.org/wiki/STUN [1]: https://jitsi.org/jitsi-videobridge/ https://jitsi.org/jitsi-videobridge/ [2]: https://github.com/jitsi/jitsi-videobridge/blob/master/doc/sfu.md https://github.com/jitsi/jitsi-videobridge/blob/master/doc/s...
