Hi Dears,

I'm working on integrating the rtpengine to work with Kamailio as RTP proxy and i have successfully configured the rtpengine in multi home mode to proxy the media and rewrite the SDP message whenever it passes trough the Kamailio internal interface to the external interface and vice versa using this command.

root@debian:/usr/local/etc/kamailio# rtpengine --interface=Kamailio-Internal/192.168.100.1 --interface=Kamailio-External/192.168.50.1 --listen-ng=127.0.0.1:22222 --pidfile=/var/run/ngcp-rtpengine-daemon.pid

Also i have configured the "i" and "e" flags in the route[NATMANAGE] to take care of the SDP rewriting direction the same way it worked before with my rtpproxy module configuration.

But the issue now is that whenever i make a call from the external to the internal the rtpengine can NOT detect the right direction as colored in red below so my question now is : How to set the direction of the rtpengine to designate that the interface 192.168.50.1 is the external and 192.168.100.1 is the internal ?
