Hi, The UAS is noncompliant to RFC 3261 (and RFC 4916). RFC 3261 section 8.2.6.2 requires that the response's To/From URI equal request's To/From URI. > So is UAC1 send ACK for this? Or UAC1 ignore > that 200OK due to the change in From header value? The UAC can basically act however it wants.

Hi,    I just need clarification is the below mentioned scenario will work properly UAC1  sending INVITE request to UAS1 -- From: "+351964901478" ;tag=AUA401YVCeghCjaA UAS1 is responding 100 Truing for that INVITE to UAC1 ---
