ISSUE 2.0
• 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 #9 followed by the trunk number (e.g., 001). This allows
the DISA caller to place an outgoing call over the selected trunk. Direct Trunk Access bypasses the
system Trunk Group Routing/ARS/Trunk Access Maps. As with dial 9 access, any toll charges are
incurred by the system.
• Call Forward
DISA callers may be able to set Call Forwarding to redirect extension calls to another extension.
Call Forwarding ensures that the user's calls are covered when they are away from their work area.
• DISA Barge-In
The DISA Barge-In option allows a DISA caller to break into another extension user'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 Toll Restriction. For
example, Toll Restriction can prevent users from dialing a 1-900 service. When an incoming DISA
caller tries to use system trunks to dial 1-900, Toll Restriction denies the call.
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 the 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 VRS Waiting Message Interval
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.
Warning Tone for Long DISA Calls
You can set up the system to provide a warning tone to DISA callers that have been on a call too long.
The warning tone can be just a reminder (which the caller can ignore) or can be followed by a forced
disconnect of the call. When the DISA caller hears the warning tone, they have the option of dialing a
code to continue the conversation or disconnect.
Trunk Continue/Disconnect Codes
Users have the option to use a Continue or Disconnect service code. The Continue service code
extends the conversation for a programmed time. If the user enters the Disconnect service code, the
call is immediately disconnected.
Example:
The following example indicates how a call will be handled with the system programmed as follows:
• PRG 14-01-25: 1
PRG 20-28-01: #
PRG 20-28-02: No Setting
PRG 20-28-03: 180
PRG 24-02-07: 600 (Used only with manually transferred Tandem Trunk calls)
PRG 24-02-10: 30 (Used only with manually transferred Tandem Trunk calls)
PRG 25-07-07: 600 (Used only with automatically transferred Tandem Trunk calls or DISA calls)
PRG 25-07-08: 30 (Used only with automatically transferred Tandem Trunk calls or DISA calls)
