[OpenSER-Users] Problem with Mediaproxy -help required

[Dan-Cristian Bogos]

Hi Andreas,

it should depend also by how well the sip ua implements the RFC. In
normal cases, I mark the natted requests with  ";nat=yes" when record
routing, and after I I will treat all the packets containing "nat=yes"
like generated from behind nat and force rtp_proxy in their case.

Some sample config:

        # --------------------------------------
        #       NAT
        # --------------------------------------

        if (nat_uac_test("7") || search("^Route:.*;nat=yes")) {

                force_rport();

                if (is_method("REGISTER")) {
                        fix_nated_register();
                        setbflag(6);
                } else {
                        setflag(7);
                        fix_nated_contact();

                        if (is_method("INVITE")){
                                fix_nated_sdp("1");
                        };

                };

        };
        # --------------------------------------
        #       Record Routing
        # --------------------------------------

        if (method=="INVITE" && isflagset(7)) {
                record_route_preset("$var(listen_ip);nat=yes");
        } else if (method!="REGISTER") {
                record_route();
        };

  if (isbflagset(6) || isflagset(7)) {

                setbflag(10);
                force_rtp_proxy();
   }

Hope that helps.

Cheers,
DanB
