Feature Operation
Direct Inward System Access (DISA)
When outside callers access extensions in the
PBX, a prerecorded message greets the caller
and gives information about how to access an
extension. You do not need the operator’s
assistance.
You may be able to access system features or call
an outside party with your password depending
on the security mode.
CAUTION
There is a risk that fraudulent telephone calls
will be made using the Outside-to-Outside
Call feature of DISA.
The cost of such calls will be billed to the
owner/renter of the PBX.
To protect the PBX from this kind of fraudulent
use, we strongly recommend:
a. Enabling DISA security (CO line Security
or All Security).
b. Keeping your passwords (verification
code PIN/extension PIN) secret.
c. Selecting complex, random PINs that
cannot be easily guessed.
d. Changing PINs regularly.
