Hi all, Remember this question from 23.1. It's solved now, thanks for help:-) All the best Christoph Von meinem Samsung Galaxy Smartphone gesendet. -------- Ursprüngliche Nachricht -------- Von: Valentin Christoph <Christoph.Valentin(a)kapsch.net> Datum: 23.01.19 15:06 (GMT+01:00) An: sr-users(a)lists.sip-router.org Cc: Scherney Theodor <Theodor.Scherney(a)kapsch.net>et>, Onic Roman <Roman.Onic(a)kapsch.net> Betreff: [SR-Users] Problem at Rx Interface - kamailio P-CSCF 5.1.6 Hi all, We are using kamailio 5.1.6, configured as P-CSCF, facing following problem. Please indicate, if you need further information – e.g. I could provide a tshark trace. If during call setup (by simulated UAs) at the terminating P-CSCF the simulated PCRF rejects the Diameter AAR message, then the kamailio P-CSCF runs into a questionable behaviour. By calling the Rx_AAR() function in configuration, the processing of the 200 OK is suspended (by the ims_qos module) and then resumed with the receipt of the AAA message. 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?
