I just wonder if this is a script error or if it is something else: I am loading an INVITE timeout using avpops and the OpenSER terminates the call. The callflow is as follows:
A -------------OpenSER------------B ---INVITE----> <---100------- ---INVITE---> <---100------ <---180------ <---180-------

Maybe openser can't match the 200 OK to the CANCEL and thus forwards it.
What is the CSeq Header of the 200 OK sent by openser? INVITE or CANCEL?

Hello,
could you make a complete network trace and send it? As I can see in the 200OK sent by OpenSER to the CANCEL, there is a Via header pointing to caller's address. Since the CANCEL was generated by OpenSER (at timeout) there should be only one Via header with OpenSER's address.
You can use ngrep on the same system as openser:
ngrep -qt port 5060

Hi Helge,
your case might be related to the thread "[Users] OpenSER not processing "200 OK" response to CANCEL message" - Cancel is sent over and over again without considering the received reply. See: http://www.openser.org/pipermail/users/2005-October/001017.html
I just fixed this on CVS - let me know if it solved your problem.
