Overview
Introduction
Two of the most commonly abused features are Call Forward
All Calls and Direct Inward System Access (DISA).
Call Forward
Call Forward is a convenient feature that allows users who are
going to be away from their desks to forward their calls to
another set or location.
Call Forward All Calls
The Call Forward All Calls feature is assigned on a per station
basis and designates the maximum number of digits to which a
user may call forward. DISA allows users in remote locations to
place calls through your corporate PBX.
Types of abuse
Station users have abused Call Forwarding by forwarding their
sets to either a long-distance telephone number or to a trunk
access code, then going offsite, and making a call to their sets.
With the introduction of Remote Call Forward, non-users can
abuse Call Forward if proper controls are not in place.

This section describes additional controls you can use with the
Call Forward features to stem abuse and unauthorized calls.
