[SR-Users] rtpengine symmetric RTP behavior

Hello,

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).

*rtpengine_offer("force symmetric media-address=192.168.1.10 replace-origin
replace-session-connection ICE=remove");*

*Thank you,*
* - Deep N*
