Direct Inward System Access (DISA) Security
Code
The Direct Inward System Access feature is used when calling into your system from
the outside. This feature is available on certain CO lines and from the built-in Auto
Attendant. Assignments are made by the system programmer. CO lines can be DISA
lines in the Day, Day 2, or Night mode, or any combination of these modes.
If a caller enters the system via a DISA line or built-in Auto Attendant, the caller can
then access another line to place an outgoing call through the system, in which case
the outgoing line call is charged as a call made from the DK system. To prevent
unauthorized outgoing calls through the system using the DISA feature, enter a DISA
security code as shown in the following steps.
CAUTION! Whenever the built-in Auto Attendant is installed, the DISA
security code should be used (and changed periodically) to prevent
unauthorized access of outgoing CO lines via the Auto Attendant
DISA access feature.
