Preventing Toll Fraud
Preventing Toll Fraud
As a customer of new telephone equipment, 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, or 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 remote access features.

charges. While these charges are fraudulent charges made by
persons with criminal intent, applicable tariffs state that the
customer of record is responsible for payment of all long-distance
or other network charges. Lucent Technologies cannot be
responsible for such charges and will not make any allowance or
give any credit for charges that result from unauthorized access.
