Hi,
        I am using SER.cfg file with the following configuration for the registerd users,
       if (method=="REGISTER" & proxy_authorize("localhost" , "subscriber"))
       {
      if (!check_to())
       {
       log(1, "LOG: unregistered user registration attempt\n");
        sl_send_reply("403", "Only registered users are allowed");
        break;
       };
       };

but it does not work and i gets this error,
