Direct Inward System Access (DISA)
Description
Allows an outside caller to access specific system features without operator assistance as if the
caller is an extension user in the system.
The outside caller can have direct access to features such as:
• Placing an intercom call to an extension, modem (for remote administration), external
pager (for TAFAS), Phantom extension, Extension Group or Incoming Group (except
DIL 1:N Group).
DISA built-in Automated Attendant
A DISA caller can access the desired extension simply by dialing a one-digit code.
• Calling an outside party.
To control the DISA caller's calling ability, one of the following three Security modes can be
assigned on an OGM Group basis.
Outgoing Message (OGM) can be recorded for the DISA feature. When a caller reaches the
system via DISA line, a pre-recorded message will greet the caller. DISA OGMs may be
recorded by the Manager extension or an Operator.
Warning for the Direct Inward System Access Users
When you enable the CO-to-CO Line Call feature of Direct Inward System Access (DISA)
function , if a third party discovers the password (a DISA User Code) of the system, you have
a risk that they will make illegal phone calls using your telephone line, and the cost may be
charged to your account.
In order to avoid this problem, we strongly recommend the following points:
1: Carefully maintain the secrecy of the password.
2: Specify a complicated password as long and random as you can make it.
3: Change the password frequently.
Security Mode Description
Non Security DISA callers can make both outside and
intercom calls without restriction.
Trunk Security DISA callers are required to enter a pre-
assigned DISA user code to make outside
calls.
All Security DISA callers are required to enter a pre-
assigned DISA user code to make both
outside and intercom calls.
