3.2 Telephone Features
Direct Inward System Access (DISA)
Allows an outside caller to access specific extensions, etc., as if the caller is an extension
in the system. A DISA outgoing message gives outside callers assistance, such as listing
the extension numbers or DISA built-in auto attendant (AA) numbers in the system. If the
optional OGM/FAX Detection card is not installed, callers will only hear a beep instead
of a message. This saves you having an operator. A pre-assigned DISA security code may
be necessary, depending on the mode, to access the features directly.
None Security mode: Any caller can make outside or intercom calls without entering a
DISA security code.
Trunk Security mode (default): You need to enter a DISA security code when making
outside calls.
All Security mode: You need to enter a DISA security code when making any call.
You also have the option of calling an extension or ring group using a one digit number
(DISA built-in auto attendant number) via DISA calls.
