Hi, I have a problem with two different two tags. The application is a NUA client (Version 1.12.7) which will have a registration on a broadworks PBX. The scenario is as follows:
NUA-Application --------> Broadworks PBX ----> Alice NUA Application is registered on the Broadworks PBX and calls Alice. On the Broadworks PBX it is configured that a Custom Ringback is played to the caller of Alice. Therefore the Broadworks PBX does send a Session Progress (183) to the NUA Application with SDP (= Media server). The To-Tag is set to 2126846201-1196843105609 by the Broadworks PBX. NUA-Application get the SDP and the custom ringback without any trouble. Alice is ringing. Then Alice accept the call. The PBX sends a 200 OK to NUA-Application with a different SDP (= Alice) BUT the 200 OK does have a different To-Tag (241898411-1196843111396). The NUA-Application doesn't accept the 200 OK because of the different To-Tag. The FROM Tag and the Call-ID are identical. The inbound call from Alice to NUA-Application works fine. If I set the debug options I get: nta: 200 OK was discarded. In the nta.c source code I have found the line which will fail: else if (a->a_tag && b->a_tag) (in function addr_match). Therefore the function will return FALSE and the outgoing_find function will continue with the next item in the outgong_htable_hash. I think it is a Sofia SIP bug but I am not sure. Some documents explains this behavior, too: https://lists.cs.columbia.edu/pipermail/sip-implementors/2007-August/017350.html http://www1.ietf.org/mail-archive/web/sipping/current/msg12390.html http://bugs.digium.com/view.php?id=5166 Can someone give me some hints or suggestions?
