Hi all, We are using kamailio 5.1.6, configured as P-CSCF, facing following problem. Please refer to the attached tshark trace, too.
If during call setup (by simulated UAs) at the terminating P-CSCF the simulated
PCRF rejects the Diameter AAR message (frame 46/47 at the attached trace), then
the kamailio P-CSCF runs into a questionable behaviour.
By calling the Rx_AAR() function in configuration, the processing of the 200 OK
(frame 45) is suspended (by the ims_qos module) and then resumed with the
receipt of the AAA message (frame 47).
Now the ims_dialog module is called with the dlg_terminate("all", "reason")
function, but the 200 OK has not yet been sent. The ims_dialog sends CANCEL
downstream and 488 upstream. However, the 200 OK is sent additionally. We would
rather have expected the ims_dialog module should send BYE in both directions.
When we respond the CANCEL with 481 Call/Transaction does not exist (which we
MUST according to RFC 3261), then we would expect the ims_dialog module at
least now to react with BYE in both directions.
Could you help? What's our misunderstanding? How could we proceed to get this
issue fixed?
Kind regards
Christoph
