Security of Your System: Preventing Toll Fraud
2
As a customer of a new telephone system, you should be aware that there is an
increasing problem of telephone toll fraud. Telephone toll fraud can occur in many
forms, despite the numerous efforts of telephone companies and telephone
equipment manufacturers to control it. Some individuals use electronic devices to
prevent or falsify records of these calls. Others charge calls to someone else’s
number by illegally using lost or stolen calling cards, billing innocent parties,
clipping on to someone else’s line, and breaking into someone else’s telephone
equipment physically or electronically. In certain instances, unauthorized
individuals make connections to the telephone network through the use of the
Remote Access features of your system.
