Direct Inward System Access (DISA)
Description
Allows an outside caller to access specific system features as if the caller is an extension in the
system. The caller can have direct access to features such as:
• Placing an intercom call to an extension, operator or external pager (for TAFAS: Trunk
(Outside Line) Answer From Any Station).
You also have the option of dialing route for an extension using an one digit number
(DISA built-in auto attendant number) via DISA calls.
• Calling an external party.
It is necessary to select either Non Security, Outside Line Security or All Security mode to have
direct access to these features. In Non Security mode, any caller may make outside or intercom
calls. In Outside Line Security mode, it is necessary to enter a pre-assigned DISA user code to
make outside calls. In All Security mode, it is necessary to enter a pre-assigned DISA user code
to make both outside and intercom calls. This prevents the caller from making unauthorized
calls. However, when making an outside call by Call Forwarding — to Outside Line, the call
is permitted (exception). An Outgoing Message can be programmed for the DISA feature.
When a caller reaches the DISA line, a pre-recorded message will greet the caller. Two
different DISA messages may be recorded by the operator or manager. Thus, one message may
be used in day mode and the other in night mode, or they can be used for different outside lines.
Warning for the Direct Inward System Access Users
When you enable the Outside – Outside 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 call 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.
