|What is toll fraud?
Toll fraud is the theft or unauthorized use of long distance phone service. Toll fraud takes many forms but is especially prevalent to phone systems that have not been secure, or where lax security measures are in place. Toll fraud is a problem worldwide, and fraudsters can easily rack up tens of thousands of dollars in long distance charges before the phone’s administrator is even aware of a problem.
How does it occur?
How can you protect your voice system?
Toll restriction: International locations are the major destination for toll fraud calls. It is recommended that your company blocks all international numbers and only enable calls to those places that you need to call. Some systems allow for passwords to be required for long distance calls. If this is a possibility, we recommend you change the passwords regularly, and especially when an employee has left the company.
Limit access: Limit system access to authorized personnel only, even during company business hours.
External transfer: Restrict call forwarding and call transfer features, especially to external numbers. Program your phone system so that extensions can forward only to known numbers, and restrict all others. Never forward a caller to 901 or 90#.
Software patches: Make sure your phone and voicemail systems are up-to-date and that all current patches have been installed.
Monitoring: Monitor calling patterns and usage on a regular, scheduled basis. High costs can be generated in a very short period of time and will continue until action is taken to stop it.
Block Collect Calls: Block the system from accepting reverse charges on telephone calls – opt for a toll-free number instead.
Invalid Access Attempts: Identify invalid access attempts to your DISA and route them to an operator. Implement DISA ports that drop the line when an invalid code is entered and program your PBX to generate an alarm when an unusual number of invalid attempts are made, and to disable the port after a set number of invalid attempts.
Modems: Eliminate three-way calling on all extensions that use modems. Physically disconnect modems that are not in use.
