Place a xlog message inside the IF statement, to see if you ever get there :


                 if ($stat(active_dialogs)>=1){
                 xlog("we have more than 1 call(s) - currently 
$stat(active_dialogs) \n");
                 sl_send_reply("503", "Service Unavailable");
*   exit;*
                 }
