Direct Inward System Access (DISA)
Allows an outside caller to access specific extensions or DISA built-in auto attendant
(AA) numbers in the system after hearing a short beep, as if the caller is an extension in
the system. 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.
