[OpenSIPS-Users] NAT configuration residential script [SOLVED?]

[campusvtv]

Hello,

I don't know if is the best solution but I changed this block:

onreply_route[handle_nat] {
         if (nat_uac_test("1"))
                 fix_nated_contact();
         if ( isflagset(NAT) )
                 rtpproxy_answer("ro");
         xlog("incoming reply\n");
}

with

onreply_route[handle_nat] {
         if (nat_uac_test("1"))
                 fix_nated_contact();
         if(status=="200") && has_body("application/sdp") {
                 if (nat_uac_test("8")) {
                         xlog("Detect NAT on 200 OK\n");
                         fix_nated_sdp("7");
                 }
         }
         if ( isflagset(NAT) )
                 rtpproxy_answer("ro");
         xlog("incoming reply\n");
}

So if OpenSIPs detect 200 ok SDP c line is a private IP 
(nat_uac_test("8")), change this IP with public IP taked from source 
message address.

Now calls from XLite to Jitsi and from Jitsi to Xlite work correctly.

Regards
