Is there an email in this long thread that summarizes the issues? It's impossible to follow this thread. :) I'm not clear on what the issues are with pre-conditions that make failed offers concept break. To me, pre-conditions are basically not real SDP offers; they're conditional offers. Until the *all* the conditions are met, it's not "committed". You continue using the last committed state. I know there are race conditions, but considering how rare pre-conditions are in the real world (especially in re-Invite's), that I'm having trouble imagining why we should care about corner cases of such. Regardless, I vote for any fixing that needs to happen because of pre-conditions should be around changing pre-condition logic, even if it means completely re-writing how pre-conditions works - don't change normal SIP or SDP. (not that anyone is proposing it, I just can't tell form this thread) Re-Invites and SDP offer/answer have so many interop issues in the wild even without pre-conditions, that this whole thread scares me. :( -hadriel _______________________________________________ Sipping mailing list https://www.ietf.org/mailman/listinfo/sipping This list is for NEW development of the application of SIP Use sip-implementors@xxxxxxxxxxxxxxx for questions on current sip Use sip@xxxxxxxx for new developments of core SIP
