Long Distance & International Phone Fraud

Toll fraud is on the rise as hackers access corporate voice systems and find an open road to major telecom networks.

Who is at risk?

Any business with a voice system that provides out-dial or through-dial capabilities.

How do hackers access the system?

Unauthorized access to a system is usually gained through voice mail menus protected with simple passwords (1111, 2222, 1234, etc.) or unchanged factory default passwords. Once in the system, hackers use system commands to gain dial tone and place long distance and international calls that appear as originating from the business.

How can this impact my business?

Calls may be placed across your long distance carrier’s network or completed on alternate networks, resulting in charges to your account. As the owner of the telephone system, you are responsible for these toll charges, not your toll provider (outlined in the TDS Fraud Policy).

What can I do to prevent phone fraud?

A strong step towards protection is through good password management policy and practice. In addition, if your business does not require International Calling, contact TDS and have it removed.

Businesses with privately owned voice systems are responsible to ensure the devices are properly secured before activation AND are responsible for all charges incurred through the system. It is recommended to contact your Voice Mail or PBX vendor to have your system evaluated by a professional and take the necessary steps to prevent against possible fraud.
