DIRECT INWARD SYSTEM ACCESS (DISA)

Direct Inward Dial Access (DISA) allows an external caller to access ADIX
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 also
have 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 require 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.
