Hello,

I've found a "solution" for this problem, the problem was that i had the ip
addres of the Asterisk server on the table "domain";
I have this configuratíon on my script:

 if (!(method=="REGISTER") && is_from_local())  /*multidomain version*/
 {
   if(!check_source_address("0")){
   if (!proxy_authorize("", "subscriber")) {
    proxy_challenge("", "0");
   exit;
  }
  if (!db_check_from()) {
   sl_send_reply("403","Forbidden auth ID");
   exit;
  }
 ##
  #xlog("L_WARN", "Thanks for the authorization - The call [$ru] will
continue to the destination - see ya ;) ; => 200 OK to NON REGISTER");
  consume_credentials();
 ## # caller authenticated
 }
 xlog("L_INFO","la IP SI esta dada de alta en el sistema");
 }
 xlog("L_INFO","no entra al bucle");
 # preloaded route checking
 if (loose_route()) {
  xlog("L_ERR",
  "Attempt to route with preloaded Route's [$fu/$tu/$ru/$ci]");
  if (!is_method("ACK"))
   sl_send_reply("403","Preload Route denied");
  exit;
 }
