Disa Toll Restriction; Disa Operating Modes; Department Calling With Overflow Message; Warning Tone For Long Disa Calls / Trunk Continue/Disconnect Codes - NEC UNIVERGE SV9100 Features And Specifications

A DISA caller may dial 0 for the system operator.
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 select a specific trunk for outgoing calls through the system. To directly access a
trunk, the user dials Service Code
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 can 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/Tie Trunk Barge-In
The DISA/Tie Trunk Barge-In option allows a DISA/Tie Line 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 can 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.
