Hi,

I am having the same problem again.... SER just keeps on sending me
back timeouts for SUBSCRIBES... The problem, as I described in
previous emails, persists for any other presentity except myself.

Here's a part of ser.cfg:

. . . . . .

 if(method=="SUBSCRIBE") {
      if (!www_authorize("sip.interlab.ait.ac.th", "subscriber")) {
          log(1, "Authentication for SUBSCRIBE");
          www_challenge("sip.interlab.ait.ac.th", "0");
          break;
      };

      if(!lookup("location") ) {
          log(1, "No registered user found for SUBSCRIBE request");
          sl_send_reply("404", "Not Found");
          break;
       };
  };

  if(method=="NOTIFY") {
       if (!www_authorize("sip.interlab.ait.ac.th", "subscriber")) {
          log(1, "Authentication for SUBSCRIBE");
          www_challenge("sip.interlab.ait.ac.th", "0");
          break;
      };

       if (!lookup("location")) {
          log(1, "No registered user found for NOTIFY request");
          sl_send_reply("404", "Not Found");
          break;
       };
  };

  if( !t_relay() ) {
     sl_reply_error();
  };

 . . . . . . . .


Here are the traces:

And so it goes, until SER replies with Timeout.

Can you tell me what is wrong???
