DISA Single Digit Dialing
Description
DISA Single Digit Dialing is an option that allows incoming callers to dial single digits to reach selected
stations within the system or selected hunt groups. This reduces the need for complicated dialing
instructions when a Voice Service Unit is used. Single Digit dialing allows selection of 5 individual
stations that may be dialed by entering the digits [1] through [5]. Users who are familiar with the system
may bypass the single digit dialing mode and dial other stations by dialing [6] + the station number of the
station they wish to call. For more information, also see Single Digit Dialing, page 148 of this document.
DISA Single Digit Dialing must be programmed on the system.
Programming
The Trunk must be programmed for DISA operation. For more information on programming DISA, see
Direct Inward System Access (DISA) on page 64 of this document.

played. If the DISA line is programmed for Single Digit Dialing, the system will route the incoming caller
