[Serusers] bridging SER peering other Sip Servers - sr-users

28 Oct 2005


      Hello to all,
I have my SER in bridging mode (with two IPs in two non routable 
networks), with rtpproxy and nathelper:
 rtpproxy -l 10.0.0.135/193.136.2.205
And the clients in the private and public networks can speak each other 
with no problems.
But in the calls from the private network to external SERs (for example: 
user@iptel.org), the speech only passes one way (from my private 
IPclient to the user@iptel.org)
Can someone tell me what could be the problem?
These are my routing lines:
if (lookup("interno")) {
       if (dst_ip == 10.0.0.135){
           if (force_rtp_proxy("FAII"))
             t_on_reply("1");
       }
       if (dst_ip == 193.136.2.205){
           if (force_rtp_proxy("FAEI"))
           t_on_reply("1");
       }
      } else if (lookup("externo")) {
       if (dst_ip == 10.0.0.135){
             if (force_rtp_proxy("FAIE"))
           t_on_reply("1");
       }
       if (dst_ip == 193.136.2.205){
         if (force_rtp_proxy("FAEE"))
           t_on_reply("1");
       }
     } else {
           sl_send_reply("403", "Utilizador nao Encontrado");
       break;
     };
(....)
Thats my external routing section:
if( !uri=~"@fccn.pt"){
if (!method=="REGISTER")
# internal IPs must use RTP proxy to call user@iptel.org
           if (dst_ip == 10.0.0.135){
             if (force_rtp_proxy("FAIE"))
             t_on_reply("1");
             route(1);
             break;
           }
          record_route();
          t_on_reply("3");
          t_relay();
        break;  
      }
(....)
onreply_route[1] {
            if (!(status=~"183" || status=~"200"))
                break;
           force_rtp_proxy("FA");
}
