is used by other machine at the same LAN or not. If yes, contact to authorized
person. Check whether Gateway address is entered correctly. Ping to
telephone’s IP from other computer at that LAN. (by using Command Prompt
and write C:\ ping 192.168.178.247.) If you get response, you can open web
interface, if not please check network settings and check whether they are the
same with NT62I or not. If problem is not solved, please contact with service.
