1.15 Optional Device Features

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 the operator. Callers can listen to a DISA 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 outside (CO) line calls, when they are outside the office.

This DISA OGM can guide callers and allow them to:

•Call an extension by dialling the extension number.

•Call another outside party via the outside (CO) lines of the PBX.

•Access the desired extension simply by dialling a single-digit number (DISA Automated Attendant [AA] number) using DISA AA service.

DISA OGM

When a call arrives on a DISA line, callers will hear a DISA OGM or a short beep. When the DISA AA service is active, this DISA OGM will direct callers to dial the appropriate digit (DISA AA number) to be connected to a specified destination. To access other PBX features, such as making intercom or outside (CO) line calls, the caller may dial the appropriate numbers while the DISA OGM is playing.

An extension assigned as the operator or manager extension can record a DISA OGM ( 1.15.5 Outgoing Message (OGM) for DISA/UCD).

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. The PBX can store up to 10 destinations that can be called by dialling a DISA

AAnumber (0–9) for each DISA OGM ( DISA Built-in AA [501]). These destinations can be an extension number ( Extension Number [009]), an extension group number ( Extension Group [600]), or the DISA AA number of a 3-level DISA OGM ( 3-level AA Assignment [540-549]).

During or after the DISA OGM announcement ( DISA Wait Time after OGM [505]), or after a short beep ( Intercept Time for Internal DISA [515]), the caller may dial a DISA AA number as directed by the DISA OGM (e.g., "Press 1 to speak to Sales. Press 2 to speak to Support.").

Each DISA AA number directs the call to a preprogrammed location.

Since DISA AA numbers are single digits, if the caller dials a second digit within a preprogrammed time period ( DISA AA Wait Time [517]), DISA AA service will be bypassed because the PBX will assume the caller is trying to access a specific feature.

When the DISA AA service is used, Incoming Dial Mode must be set to "With AA" through system programming ( DISA Incoming Call Dial Mode [500]). When "With AA" is selected, the PBX regards caller- dialled digits "0" through "9" as DISA AA numbers. If no destination is assigned to "9" or "0", the PBX regards the number (9/0)* as the Automatic Line Access number ( Automatic Line Access [121]) or Operator Call number.

Note

*For New Zealand, the Automatic Line Access number may be either 1 or 9.
