Hi Paul, Thanks for the response. Reply inline. > If the question is about the rollback, or not, of > the Contact address... That was one of the questions. > IMO there was never really any question of rolling > back Contact. Draft-holmberg-sipping-reinvite-rollback-00 section 1 indicates: "Different solutions were discussed, and it was agreed that session parameters that have been sucessfully updated are not rolled back in the case of a re-INVITE failure. The same applies to any other parameter, e.g. that remote target, that have been sucessfully changed." Draft-holmberg-sipping-reinvite-rollback-00 does contain normative text associated with the last sentence of the above quote. It also does not define "sucessfully updated" concerning session parameters and other parameters; thus I'm not sure what it means. 1) received re-INVITE, 2) sent 18x, 3) reliable 18x's PRACK successful prior to sending failure response, 4) sent INVITE 2xx 5) UPDATE transaction was successful during the re-INVITE transaction which failed and/or 6) something else. > If the request contains a new contact, > and if the request itself succeeds, then the Contact > is updated, and isn't ever rolled back after that. What is meant by "request itself succeeds": 1) received re-INVITE, 2) sent 18x, 3) reliable 18x succeeds PRACK successful prior to sending failure response, 4) sent INVITE 2xx 5) UPDATE transaction was successful during the re-INVITE transaction which failed and/or 6) something else. _______________________________________________ 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
