[SR-Users] Issue with ACK behind NAT

[Alberto Sagredo]

Hi Alex. Both Kamailio and Asterisk are in same network.

Asterisk and Kamailio are behind NAT

Im working with record route.. to see if i solve this

 if (is_method("INVITE") && is_ip_rfc1918("$si"))  {

        record_route_preset("192.168.0.170:8002;nat=no");

         xlog("L_INFO", "Source IP  : $si \n");

        }


        if (is_method("INVITE|SUBSCRIBE") && !is_ip_rfc1918("$si") ){

              xlog("L_INFO", "Source IP  : $si \n");

                record_route();

        }


Any other recommendation is well appreciated
