Hi All We are facing erorr situation with B2BUA node.
User A register with registrar via SBC B2BUA, here user side registration expire timer is 30 sec and core side (between sbc and registrar)regristration expirr timer is 300 sec. Here situation is user initially registered ok. But becoz of network issue user unregister. For this registration user side source port is 5060 and sbc side is5060. Between sbc and registar port always change as per configuration. After 36 sec same user A again register via sbc where user side ports are same 5060 at source and same 5060.same entry we can see on sbc where core side port are diffrent than previous register this valid entry. Now 1st registration already vanished and for that registrar send notify message which showing this Notify is to terminate old registration with subscription state is terminated reason deactivated and expire =0. Here sbc sending same notify to user A and deleting new registration entry from sbc. Once user A recive this notify it automatically deregister. Becoz of this im facing weired issue. Not sure its sbc issue as it passing wrong notify which come for old registration. Here as mentioned source ports (5060-5060) for 1st and new register is same. Im assuming sbc need to fail that notify with sip 481 as old Registration transction or dialog no more present on SBc and no entry for that registration at SBC. Pulz help me with correct behaviour at sbc, user and registrar with standard refernce.
