DISA Intercept Routing—No Dial

a.Disable: The call will be terminated.
b.Operator: The call will be redirected to the operator.

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.

Outgoing Message (OGM)
When a call arrives on a DISA line, a prerecorded DISA message will greet and guide the caller.
Any extension assigned as the manager can record outgoing messages (OGMs). (→ 12.1.2 OGM (Outgoing Message))
