Security of your systems: 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.
