UA -> WAN(X.X.X.X) -> Kamailio(LAN 192.X.X.148) -> internal PBX(LAN 192.X.X.131) I have a WN IP forwarded to and internal Kamailio server which is sitting in front of an asterisk server. SIP requests are sent to asterisk from Kamailio via dispatcher . SIP client can register via WAN and Kamailio to asterisk , I have rtpenine configured as below. /usr/sbin/rtpengine --interface=192.X.X.148!X.X.X.X --listen-ng=7722 --timeout=60 --silent-timeout=3600 --pidfile=/var/run/ngcp-rtpengine-daemon.pid --table=0 --log-level=6 --log-facility=local7 --log-facility-rtcp=local7 --homer=192.168.200.5:9060 --homer-protocol=udp --homer-id=2002 But SIP SDP when sent to asterisk is still show the WAN IP of the Sip client in the SDP offer that goes to asterisk , ive tried adding parameter “via-branch=” and “auto-bridge” to rtpengine_offer but they don’t seem to make a difference , is there anyone way I can force the SDP offer that goes to the backend PBX to use the IP of Kamailio server that rtpengine is running on rather that the WAN IP that I’m advertising(X.X.X.X) ?
