"Security of Your System: Preventing Toll Fraud," in Appendix A, "Customer
Support Information." For security in a private network, see the Network
Reference .
When you change your system, be aware of the following special considerations
that apply to toll calling:
The Remote Access feature allows employees to dial into the system by
dialing the number of a trunk designated for remote access. After a remote
access caller reaches the system, you should make sure that he or she
must dial a password (called a barrier code ). After gaining access to the
system, the user can, among other things, select a regular or special-
purpose outside line (for example, a WATS line) or a pool or an ARS line to
make outgoing calls. You can apply calling restrictions to outside lines used
to access the system remotely; you can also apply restrictions to barrier
codes just as though they were system extensions.
Some voice messaging systems (described later in this chapter) permit
outcalling . That is, these systems can be programmed to call an outside
number to deliver messages or faxes. This feature can be used for toll
abuse, so consider calling restrictions for lines used by such systems.
Remote Call Forwarding can be allowed or disallowed for your system. If
allowed, a user can have calls forwarded to an outside number. (This is not
permitted at extensions or on lines where calling restrictions have been
applied.)
When restrictions are applied to extensions, rather than to lines/trunks, a
person can ask a co-worker or operator with fewer restrictions to make a
toll call on his or her behalf.
Authorization codes are intended to allow people with less restricted
extensions to use extensions where there are more restrictions. If you use
authorization codes to enforce restrictions, people may discover that, at
some extensions, they can make calls without using authorization codes
and gain more privileges than their own extensions allow.
The sections below list the types of restrictions, including the following
information:
Whether the restriction is applied to an extension, line, remote access
barrier code (acting as an "extension" for a remote access user), or a
combination
What other restriction features it works in conjunction with, as well as mode
restrictions
