Toll fraud & voice security

Toll fraud or dial-through fraud is a growing global crime and if your phone system/PBX becomes a victim of hacking and phreaking attacks, your phone bill could be 10-100 times higher than usual - and sometimes even higher than this - but you'll be expected to pay for this unauthorised call traffic.  Control Phreak stops all toll fraud, dial-through fraud and phone system/PBX hacking continuously all day, every day providing automatic toll-fraud detection and protection.
