* To connect to a single peer, send `SESSION <uid>` where `<uid>` identifies the peer to connect to, and receive `SESSION_OK`
* All further messages will be forwarded to the peer
* The call negotiation with the peer can be started by sending JSON encoded SDP and ICE
* The call negotiation with the peer can be started by sending JSON encoded SDP (the offer) and ICE
* You can also ask the peer to send the SDP offer and begin sending ICE candidates. After `SESSION_OK` if you send `OFFER_REQUEST`, the peer will take over. (NEW in 1.19, not all clients support this)
* Closure of the server connection means the call has ended; either because the other peer ended it or went away
* To end the call, disconnect from the server. You may reconnect again whenever you wish.
