Hi,

If the media is coming from a different IP address than the signalling, you may need to use the ‘r’ flag to force the address in the SDP to be trusted.

You should also use the same flags in the same order, in the on-reply route. (This is all in http://kamailio.org/docs/modules/4.3.x/modules/rtpproxy.html#idp15555616)

rtpproxy_manage(“eir”);

 

In the withindlg route, you don’t need to specify the ei/ie direction, but you will need to pass the ‘r’ flag.

 

Regards,

Hugh

 

 

Hello,

 

Yeah, I also noticed I forgot the / . Now the SDP c parameter is set correctly, but the audio from private to public isn’t relayed by rtpproxy.

 

I ran a tcp dump on both interfaces (private and public), and it showed me RTP is being received from Freeswitch and also from our carrier, but nothing is passed between the two interfaces by rtpproxy. Any ideas?

 

Below a slim version of my config:

 

Request_route {

 

                if (is_method("INVITE")) {

                               record_route();

                               if (has_body("application/sdp")) {

                                               rtpproxy_offer("ei");

                               }

                }

 

}

onreply_route[MANAGE_REPLY] {

                if (has_body("application/sdp")) {

                               rtpproxy_answer("ie");

                }

}

 

route[WITHINDLG] {

                if (!has_totag()) return;

                if (loose_route()) {

                               if(is_method("BYE")) {

                                               rtpproxy_manage();

                               }

                               route(RELAY);

                               exit;

                }

}

Hi,
Try starting rtpprpxy with a / in between the two IP addresses.
For example -l 1.1.1.1/2.2.2.2
Besides that it depends where you are placing your rtpproxy function.

BR,
