Thanks Enrico,

Yes, you are right. I was missing a detail.

Now imagine you are not using your own wire protocol but a standard one,
where accepting the request doesn't imply accepting or rejecting the SDP
offer, since SDP has its own methods to accept or reject the call as
commented before.

A --{"action":"CALL","sdp":"v=0..."}-> B
B --{"action":"ACCEPT CALL","sdp":"v=0..."}-> A

A --{"action":"CALL","sdp":"v=0..."}-> B
B --{"action":"ACCEPT CALL","sdp":"v=0\r\nm=video 0..."}-> A
