For several months now our production IP Office System is being continuously attacked by a hacker trying to login to the system admin and VoIP extensions. We have a strong passwords, but it is still troubling me that it is continuous. In the amount of time for me to type this message almost 50 hits on the user password for VoIP phone and 3 attempts on the system admin. The system admin one provides the remote IP Address which I am unable to ping. Any suggestion on how to stay ahead of the bad guy?
