SecurityAlert:
As a customer of a new telephone system, you should be aware that there
exists 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 remote access features.
The Remote Access feature of your system, if you choose to use it, permits
off-premises callers to access the system from a remote telephone by using
an 800 number or a 7- or 10-digit telephone number. The system returns an
acknowledgment signaling the user to key in his or her barrier code, which is
selected and administered by the system manager. After the barrier code is
accepted, the system returns dial tone to the user. If you do not program
specific restrictions, the user will be able to place any call normally dialed
from a telephone associated with the system. Such an off-premises network
call is originated at and will be billed from the system location.
The Remote Access feature helps the customer, through proper
administration, to minimize the ability of unauthorized persons to gain
access to the network. Most commonly, phone numbers and codes are
compromised when overheard in a public location, through theft of a wallet
or purse containing access information, or through carelessness (writing
codes on a piece of paper and improperly discarding it). Additionally,
hackers may use a computer to dial an access code and then publish the
information to other hackers. Enormous charges can be run up quickly. It is
the customer's responsibility to take the appropriate steps to properly
implement the features, evaluate and administer the various restriction
levels, protect access codes, and distribute access codes only to individuals
who have been fully advised of the sensitive nature of the access
information.
