Hi Folks, I'm looking for your views on this scenario,
UAC UAS INVITE ----------------> <-------------------- 100 (With changed b-number, username part changed of the TO header field as compared to INVITE) INVITE ----------------> (re-transmit of same INVITE, CSeq same) <-------------------- 100 <-------------------- 180 INVITE ----------------> <-------------------- 200 INVITE ----------------> <-------------------- 200 ... UAC is not identifying the “100 Trying”, “180 Ringing” and “200 OK” received from the terminating side and keep retransmitting the “INVITE” to the terminating side because UAS has changed the B-Number in the “100 Trying”, “180 Ringing” and “200 OK”. Is this a correct behavior? I'm unable to see the ideal behavior in the RFC for this scenario, I believeinstead of ignoring the incoming 100, 180 & 200 received from terminating side, UAC should generate a valid response to these incoming messages.
