Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. >Category: modules Group: ver devel >Status: Closed >Resolution: Fixed Priority: 5 Submitted By: Federico Giannici (giannici) Assigned to: Bogdan (bogdan_iancu) Summary: Correct handling of branch attributes Initial Comment: The RFC says that: 1) The 2xx ACKs are a new transaction. 2) Each new transaction must have a different branch in the Via header. So the "branch" attribute of 2xx ACKs should be different of the one used for the INVITE/reply. We should verify that: 1) SER generated ACKs are correct. 2) Transaction maching algoritm is correct (the "branch" of INVITEs and corresponding ACKs don't have to be the same). ---------------------------------------------------------------------- >Comment By: Bogdan (bogdan_iancu) Date: 2006-06-21 20:13 Message: Logged In: YES user_id=1275325 in stateful mode, the building of ACK via branch is fixed - it guaranteed to be different that the one fro INVITE. regarding the stateless processing, is still to implement the behaviour described on the sip-implemetors mailing list (copying the latest stateful branch). This algorithm will apply for all requests. For this I will open a new bug report. ---------------------------------------------------------------------- Comment By: Bogdan (bogdan_iancu) Date: 2006-06-13 14:01 Message: Logged In: YES user_id=1275325 The 2xx ACK are forwarded by OpenSER using a stateless function from core and the used branch will be "0" string. So, it is different from the INVITE branch, but is not correct since it is not unique. The same problem is when statelessly forwarding requests - the banch will be set to "0". There is a solution for this.
