DISA Intercept Routing—No Dial
If
the caller fails to dial any digits within a preprogrammed time period (DISA 1st Dial Time for Intercept) after
hearing the outgoing message (OGM), one of the following can be selected through system programming:
a. Disable: The call will be terminated.
b. Operator: The call will be redirected to the operator.
c. AA-0, AA-9: The call will be redirected to the destination assigned to that AA number.

DISA Built-in Automated Attendant Number (DISA AA Service)
After listening to the outgoing message
(OGM), the caller may dial a single digit (DISA AA number). The
destination for each DISA AA number can be assigned for each message. It is also possible to assign other
DISA floating extension numbers as the destination (Multistep DISA AA Service).
If the caller dials a second digit within a preprogrammed time period (DISA 2nd Dial Time for AA), the DISA
AA service is not employed.
