Make sure force_rtpproxy is called also in reply route, and make sure the reply route is activated (t_on_reply).

See the default config file for how it works.

For debugging use (or Wireshark ...) ngrep -i any -W byline port 5060 and analyze the SDP before and after Kamailio.

Also, add xlogl() statements to the config file before and after activation of rtpproxy and verify that you see them in the log file.

Hi

I want to use Kamailio to handle both signalling and media always. My scenario is the following PSTN==>KAMAILIO==>ASTERISK. I have a dialplan that points to ASTERISK when a call comes into Kamailio. Signalling is fine, however i cant seem to get the Media to work, i have installed the RTPPROXY as suggested by RTPPROXY module and have implemented it into the routing logic, however i have one way audio. The PSTN side cannot hear anything.

I dont use the Kamailio for sip registrations or for users behind NAT. I just use a simple dialplan for forwarding SIP messages to our certain VOIP carriers, however some of our carriers request that we use both signalling and media from the same IP thats why i need to implement this scenario. Is this possible?

Thanking you in advance for your help! Phillip
