Direct Inward System Access (Disa) - Iwatsu ICON Series IX-5910 Owner's Manual

DIRECT INWARD SYSTEM ACCESS (DISA)

Direct Inward System Access (DISA) allows an external caller to access
Iwatsu Enterprise-CS intercom dial tone by dialing the phone number of an
outside line that is dedicated for DISA. DISA gives the external caller the
ability to make intercom, hunt group, and external calls, the ability to
forward calls, and access to the paging system. The feature operations for
DISA calls are the same as those for the Single Line Telephone. Use of
certain DISA features requires a security password to control abuse. The
password may be six digits in length. External calls and paging access
require the use of a password. The IX-RMPU card is required for DISA
operation.
