Does "early-session" implicitly indicate that? >>> same as above.. If not then, 1. A B ---INVITE(Require: early-session) ----> (INVITE is without 100rel option) As 100rel is not there what will be response from B? 2. A B ----INVITE(Supported: early-session) with OFFER ----> <---- 180 Reliable with early-offer & ANSWER---- (INVITE is without 100rel option ) What will be response from A as no 100rel supported? >>> UAS will send offer & answer with 183 (session progress) with the early >>> session SDP for early media.... once A receives that it will send a PRACK >>> ack'ing the receipt for the SDP with Content Disposition of 'early >>> session'..
