Toll fraud otherwise known as phone hacking or phreaking is a hugely profitable activity for organised criminals. Hackers hijack your phone system and create a huge phone bill full of premium rate calls to just about any location.

Fraudsters can strike any system, regardless of whether you have an analogue, digital or IP-based system. Usually, they strike out of hours on public holidays, evenings or at weekends when the likelihood of detection is lower, often companies don’t realise they have been breached until the phone bill arrives.

A single attack typically costs a business thousands of pounds and as a worst-case scenario result in bankruptcy as toll fraud is ultimately the businesses responsibility.

Voice Firewall

You wouldn’t leave your PC or data network unprotected against malicious attacks, so why treat your phone system any different?

Opus Teams Voice Firewall solution provides businesses with the best kind of defence against toll fraud. It works by recognising unauthorised numbers and preventing them from connecting to the main system on both outbound and inbound calls, blocking any opportunity the hacker has to penetrate the system.

Each Voice Firewall we provide is further configured specifically to each business to determine which numbers should be blocked during office hours, ensuring you don’t lose potential business from new callers the system doesn’t recognise.

We can also limit the number of simultaneous inbound and outbound calls out of office hours further enhancing your phone system security. For additional peace of mind, a daily event log is created showing the blocked calls and numbers.

Business Benefits:

  • Blocked calls are added to the dynamic call barring list once a calling limit is reached protecting you from repeated attacks.
  • Protects analogue, digital (ISDN) and IP trunks (exchange lines) of any number.
  • Secures your phone system from toll fraud attacks without limiting any of the existing functionality of your phone system.

 

  • A simple and quick installation as it connects easily between your phone system and network termination point.
  • View a daily summary of inbound, outbound and diverted calls, as well as all killed calls and the reason why they were killed.
  • Automatically monitors every event that occurs on your phone system from picking up the handset to ending a call & instantly evaluates against your own predefined security rules.
