Peer-to-Peer AV-transmission on Jitsi — why is AV-data running via server?

I am new with Jitsi and I have not found an answer to my question by searching the web.
AFAIK, the initiator of an AV-connection connects to a server (TURN STUN) and the client(s) will also connect to this server. Therefore the actual IP-adresses of the both participants are known and a direct connection between both participants will be established. After that, all data is exchanged directly between the both participants and not via the server.
I have seen discussions about, how to reduce the load on a Jitsi server, especially when there are 20 or more participants in a AV-conference, because all AV-data would be handled by the Jitsi server. I conclude, that this cannot be a peer-to peer connection.

Could please someone explain to a newbee, why Jitsi works like this and not via peer-to-peer-connections?

OK! Solved by myself. I have read this explanation and now I uderstand, that WebRTC can be used in peer to peer mode only, if there are only two participants.
If there are more, then all the AV-streams have to be distributed. And this is done by the Jitsi Videobridge which of course, has to reside on a server.
