Control Phreak will keep your PBX safe from phreakers automatically - all day, every day.

Close enough isn't good enough when it comes to voice security.  It's all very well being told that passwords and alerts and monitoring will keep you safe from phone hackers - but they won't and deploying any of these methods to secure your phone system against phreaking is taking the close-enough option.

Phone hacking, PBX hacking, phreaking, toll fraud, dial-through fraud.  They're all the same thing.  It's controlled by organised crime and big business which funds international terrorism - and they could cost you a fortune in telephone calls you didn't make but your telco will demand you pay because they were made from your exchange lines and extensions via your phone system. 

When phreakers strike, you could end up with a phone bill more than 100 times higher than normal.  And it doesn't matter what sort of phone system you have.  All PBXs are vulnerable to phreaking attacks by criminals intent on making you an unwitting accomplice in this global fraud which funds terrorism.

Phreaking is a preventable crime.
