Hello, did not looked into the pcap, but you should try to debug why it uses the wrong port. Maybe you are adding wrong SDP content to the SIP messages you route in your setup. If its add wrong SDP, try to debug why this happens. Cheers, Henning -----Original Message----- From: gui <glengagne(a)gmail.com> Sent: Freitag, 3.

I am using same rtp engine at origination and termination. I am sending rtpmanage for invite and 183 session progress at both origination and termination. My issue is that Rx is not sending for the proper media flow component to PCRF. At origination it is considering a media flow between A 50034 and RTPEngine 49186 (instead of considering RTP Engine Port 49152) At Termination it is considering a media flow between B 50054 and RTPEngine 49132 (instead of considering RTP EnginePort 49170) Any idea why?

In fact, to summarize my issue, I see that : At Termination, PCSCF is asking PCRF to setup QoS for a flow between the RTP Port of the SDP offer it received and the RTP Port of the SDP anwer it received. While it should ask to set QoS for a flow between the RTP port it allocated (after rewriting SDP Offer) and the RTP Port of the answer it got from B. Same kind of issue at Origination.
