1.15.6 Direct Inward System Access (DISA)

Description
Direct Inward System Access (DISA) allows outside callers to be connected to their desired PBX
destinations without the use of an operator. Callers can listen to an outgoing message (OGM) instructing
them as to which numbers to dial to be connected to the person or department they would like to speak with.
DISA can also give PBX users access to PBX features, such as making CO line calls or changing their
extension settings, when they are outside the office.
To use DISA, the incoming call must first be directed (via DIL distribution) to a floating extension number
assigned to an OGM used by DISA. This OGM can then guide callers and allow them to:
• Make an intercom call to an operator, extension, or to a floating extension number, such as an
incoming call distribution (ICD) group or a modem used for remote system administration.
• Call another outside party via the CO lines of the PBX.
• Set or operate PBX features, such as Call Forwarding (FWD) or Extension Dial Lock, remotely.
OGM
When a call is directed to a floating extension number assigned to an OGM used by DISA, callers will hear
the OGM. If using the DISA Automated Attendant (AA) service, this OGM will direct callers to press the
appropriate digit (DISA AA number) to be connected to a specific destination. To access other PBX features,
such as making intercom or CO line calls, the caller may dial the appropriate numbers while the OGM is
playing.
Any extension assigned as a manager can record an OGM. (→ 1.15.5 Outgoing Message (OGM))

DISA AA Service

DISA AA service allows a caller to dial a single-digit number (DISA AA number) and be connected to the
desired party automatically. Each DISA OGM can be assigned up to ten destinations that can be called by
dialing a DISA AA number (0–9). These destinations can be any destination within the PBX which has an
extension number or floating extension number.
After or while listening to the OGM, the caller may dial a DISA AA number as directed by the OGM. ("Press
1 to speak to Sales. Press 2 to speak to Support.") Each DISA AA number directs the call to a
preprogrammed location, which can even be another DISA floating extension number (Multistep DISA AA
Service).
Since DISA AA numbers are single-digits, if the caller dials a second digit within a preprogrammed time
period (DISA Second Digit Time for Automated Attendant), DISA AA service will be bypassed because the
