[Serusers] Replicate REGISTER from SER to non-SER sip server

[Matt morris]

Hi all,

I have this scenario: A SIP Client needs to register with both a SER server 
and a non-SER sip server (different domains). How can I achieve this in 
SER's config?

I have seen this example in the list to forward the REGISTER message to 
other SER servers:

if(method == "REGISTER")
   {
     if(src_ip==<IP of peer1> || src_ip==<IP of peer2>)
     {
       save_noreply("location");
     }
     else
     {
       if(!www_authorize("<my domain>", "subscriber"))
       {
         www_challenge("<my domain>", "0");
         break;
       }
       if(!check_to())
       {
         sl_send_reply("403", "Use To=username next time");
         break;
       }
       if(!save("location")) { sl_reply_error(); break; }
       forward_tcp("<IP of peer1", 5060);
       forward_tcp("<IP of peer2", 5060);
     }
     break;
   }

Would it work for my scenario? I tried it but it seems the forward_tcp line 
gave me this error:
"forward_req: ERROR: cannot forward to af 2, proto 2 no coresponding 
listening socket"

I'm using SER 0.8.14, thanks all in advance.
