• Paging
Internal and External Paging may be available to DISA callers. This allows
co-workers in adjacent facilities, for example, to broadcast announcements
to each other.
• Direct Trunk Access
DISA callers may be able to select a specific trunk for outgoing calls through
the system. To directly access a trunk, the user dials Service Code 805 fol-
lowed by the trunk’s number (e.g., 01). This allows the DISA caller to place
an outgoing call over the selected trunk. Direct Trunk Access bypasses the
system’s Trunk Group Routing/ARS/Trunk Access Maps. As with dial 0
access, any toll charges are incurred by the system. Also see Trunk Group
Access above.
• DISA Trunk Barge In
The DISA Trunk Barge In option allows a caller to break into another exten-
sion’s established call. This sets up a three-way conversation between the
intruding party and the two parties on the initial call.
DISA Toll Restriction
The digits a DISA caller dials for an outgoing call may be subject to the system’s Toll
Restriction.
DISA Operating Modes
The DISA Operating Modes determine what happens when a DISA caller forgets to
dial, calls a busy or unanswered extension or dials incorrectly. The system can either
drop the call or send it to a preset Ring Group (called a DISA Transfer Destination).
Department Calling with Overflow Message
If a DISA caller dials a busy Department Calling Group, the system can periodically
play the voice prompt, “Please hold on. All lines are busy. Your call will be answered
when a line becomes free.” while the caller waits. The interval between the voice
prompts is the DISA Overflow Message Time. When an extension in the Department
Group becomes available, the call automatically goes through. If the Department
Calling Group remains busy past the DISA No Answer Time, the DISA call routes to the
overflow destination or disconnects. (What happens to the unanswered call is set by
the DISA Operating Mode). The Overflow Message requires a VRS.
DISA Dial in Mode
You can select the method that the digits dialled by a DISA caller are routed by the
system by Program 25-01-01.
You can select Intercom mode where the received digits are used to route the DISA
caller or you can select Convert mode where the received digits are passed to the DDI
Conversion table.
When you select the Convert mode the operation of the DISA call is the same as a DDI
call, as follows:
The trunk port that the DISA call is received on will define the trunk group number
(Program 14-05-01).
