All, This was talked before but it still looks not clear:
UAC UAS ----------->F1 INVITE w/o SDP <-----------F2 18X w/ SDP1 ----------->F3 PRACK w/ SDP2 <-----------F4 200 for PRACK <-----------F5 200 for INVITE w/ SDP1 ----------->F6 ACK (w/ SDP2 ???) My questions: 1. Could 200 for INVITE in F5 carry an SDP? 2. If 200 in F5 carries the same SDP with that in 18X, should UAC send an ACK with SDP? Thanks, Leo _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
