  Make sure that you are using proper username and password and that
  subscriber table contains "194.165.196.72" as domain.

> 2,NAT problem:While we log on the server with Windows Messager or other UA software with Public IP address,it works normally.But if we use the UA software behind the router(ADSL router) ,cann't log on the SER server,and the "serctl moni"will appear the UA software(behind router) log in location(LAN address as 192.168.1.2) and record it to the MySQL "location" table of database "ser".

  You will have to configure your server to use nathelper module (just
  loading the module is not enough), a simple config example can be
  found in sip_router/etc/nathelper.cfg
