Thanks for your answer, I do not see anything wrong in the SDP, RTP
ports are correctly allocated on Invite and 183 session progress.

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.

I have an issue with Rx in my VolTE call Flow. Please refer to picture and pcap in
I am using same rtp engine at origination and termination.
I am sending rtpmanage for invite and 183 session progress at both origination and
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?
