Scams & Toll Fraud

How could an unauthorized person gain access to your long-distance service?

There are many possibilities. Thieves or hackers can:

  • Break into your PBX, using Direct Inward System Access (DISA), remote access and maintenance ports, or modems, and place calls as though they originated from your system.
  • Break into your voice-mail system and take over mailboxes, and/or steal long distance by obtaining an outside line, or by programming mailboxes to accept 3rd party billed calls.
  • Use your Toll Free (800,888,877) numbers and make calls that you didn't intend to or want to pay for.
  • Use your company Calling Card™ numbers to place international calls.
  • Go through your trash - commonly known as 'dumpster diving' - searching for codes.
  • Use your printed internal telephone directory to try & 'recruit' your employees.
  • Con your switchboard and reception staff into accepting collect calls or connecting them to long distance trunks - a technique known as 'social engineering'.
  • Bill international calls to your telephone number by employing a third number billing scam.
  • 'Shoulder surf' in airports or other public locations to obtain Calling Card numbers and authorization codes by looking over callers' shoulders as they use them.
