1.2.8 To Access Another Party Directly from Outside (Direct
Inward System Access [DISA])
Calling through DISA
To call an extension
— Calling through 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. Ask your manager for the mode
assigned to your PBX.
