Hi, I've been debating this with someone, and I'd appreciate some outside input. below is the scenario:
A -------- B INVITE -> with no supported header <------100 <------18X <------200OK with no refresher/session-expires or min-se ACK ----> <------INVITE with Session-Expires: 3700;refresher=uac and Min-SE: 600 480 -----> We suspect that the re-INVITE is what's causing the 480. my colleague is under the impression that the B-side re-INVITE should not contain any refresher since the A-side indicated that they do not support it in the initial INVITE, and this b-side behavior is non-RFC-compliant . My understanding is that this is alright as long as they set a min-se and make themselves the refresher. This scenario does not seem clear in RFC 4028. can someone please clarify and provide proof? Thanks in advance RSW _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
