Subject: [Serusers] Using AS5300 as PSTN Gateway

I have a AS5300 setup as PSTN Gateway. It works fine with VOCAL.

Now I'd like to connect SER to this PSTN gateway.

I added following line to the default ser.cfg file:

if (uri=~"^sip:1") {

    log(1, "Forwarding to PSTN\n"j);

    forward(189.101.110.132, 5060);

    break;

};

 

This will allow any dialed number starting with 1 being forward to PSTN gateway.

But it always give me busy signal.

Can anybody tell me what's wrong?

 

 

Here is my whole ser.cfg file:

  break;
 };
 if ( msg:len > max_len ) {
  sl_send_reply("513", "Message too big");
  break;
 };

 

 # we record-route all messages -- to make sure that
 # subsequent messages will go through our proxy; that's
 # particularly good if upstream and downstream entities

 record_route(); 
 # loose-route processing
 if (loose_route()) {
  t_relay();
  break;
 };

 

 # if the request is for other domain use UsrLoc
 # (in case, it does not work, use the following command
 # with proper names and addresses in it)
 if (uri==myself) {

 

  if (method=="REGISTER") {

 

# Uncomment this if you want to use digest authentication
   if (!www_authorize("vocal0", "subscriber")) {
    www_challenge("vocal0", "0");
    break;
   };

 

   save("location");
   break;
  };

 

  # native SIP destinations are handled using our USRLOC DB
  if (!lookup("location")) {
   sl_send_reply("404", "Not Found");
   break;
  };
 };
#Handle PSTN calls.
 if (uri=~"^sip:1") {
  log(1,"Forwarding to PSTN\n");
  forward(189.101.110.132, 5060);
  break;
 };

 # forward to current uri now; use stateful forwarding; that
 # works reliably even if we forward from TCP to UDP
 if (!t_relay()) {
  sl_reply_error();
 };

 

}
