Hello Andreas,
Yes, that's what I had thought, but
I am actually seeing it using two different UDP ports towards Freeswitch (send=40036 and recv=40042)
and two more ports towards SIP Client (send=40038, and recv=40040).
I am wondering if there is any setting (or flag at compilation time) that will make it symmetric.
This rtpengine is daemon only, (not using kernel module).
Thank you, - Deep N

Is there any way rtpengine can be configured to use same UDP port to receive and transmit RTP packets?
The set up I'm trying is
SIP_Client --> Kamailio/rtpengine --> Freeswitch Internet Internet LAN LAN 192.168.1.10
I tried /rtpengine_offer / in kamailio.cfg, but rtpengine seems to always use different ports to Tx/Rx the packets. (Causing Freeswitch to auto adjust its ports, which mutes the audio channel one way).
Well, rtpengine actually uses the same port to send and receive traffic towards a UA. However, it uses two different ports for the two parties, which shouldn't be an issue, because Freeswitch will only see the one port towards itself.
