Integrate videoconferencing on a website

Hi everyone,

I have to make a web application with html / javascript / php and among other things, at a certain moment, there must be the possibility of connecting two people via videoconference.
I have taken a look at WebRTC but I don’t know if it is the best way or maybe use tools like jitsi.org

1- What do you recommend me?
2- What server would be necessary to be able to carry out hundreds of videoconferences (of two people each) at the same time?

Thank you!

For just p2p calls the only server you need is a turnserver (coturn) to relay you media in case a direct connection cannot be established. You don’t need the whole jitsi infrastructure just for those. And pure webrtc and exchanging SDP will be enough.
