Sentry User Guide Emergency Conference
ProcedureTo use the Emergency Conference program, just dial the emergency number for the 
agency or department you want to reach. You will be connected to the emergency 
conference and will be able to listen and talk to other parties. If any of the extension 
lines are busy or the conference is full, the Emergency Conference program acts 
according to how your administrator has set it up. The following table illustrates 
the possible situations you may encounter.

Sentry User Guide Annoyance Trap
Chapter 4 Annoyance Trap
Overview
This chapter describes the Annoyance Trap feature, which can be monitored on the 
Sentry Alarm Control Terminal. If you need more information about the Alarm 
Control Terminal, See “Using Sentry Alarm Control Terminal” on page 3.
How Annoyance 
Tr a p  Wo r k sAnnoyance trap allows the receiver of a prank call to “trap” the caller. For example, 
a prisoner with access to a phone may repeatedly dial an emergency number, such 
as the prison fire station, just for entertainment. 
When the person answering the fire station’s phone realizes that the calls are a 
prank, he or she can dial a short series of numbers (during the call) to identify the 
caller. 
If the phone display is set up to show caller extension numbers, the receiver of the 
call sees the prank caller’s extension number on the phone display. The caller’s 
extension is also displayed on the Sentry Alarm Control Terminal, as described in 
the following paragraphs.
Annoyance Trap 
with Sentry Alarm 
Control TerminalIf Annoyance Trap is used with Alarm Control Terminal, an alarm can be set off to 
alert the operator that Annoyance Trap is being used to catch a caller. The operator 
then can see the extension numbers (displayed on the terminal screen) for the 
annoying caller and the receiver of the call. 
Annoyance Trap can also be set up to automatically include the Alarm Control 
Terminal operator in a conference call with the annoying caller and the receiver of 
the call. This allows for mediation or other types of intervention.

Using Annoyance Trap
The following procedures describe how both a person who receives an annoying call 
and an Alarm Control Terminal operator can use Annoyance Trap.
When You 
Receive an 
Annoying CallWhen you receive an annoying call, follow these steps to use Annoyance Trap:
Annoyance Trap works only if the annoying caller is still on the line. Before the 
annoying caller hangs up, do one of the following, depending on the type of phone you 
have:
Dterm phone
1. Press the TRF key. You will hear a beeping sound.
2. Dial the number assigned for Annoyance Trap. This number is usually *69, but your 
administrator may have assigned a different number. Check with your administrator 
to be sure.
Analog (single line) phone
1. Flash hook to place the annoying caller on hold. You will hear a beeping sound.
2. Dial the number assigned for Annoyance Trap. This number is usually *69, but your 
administrator may have assigned a different number. Check with your administrator 
to be sure.
If the caller is still on the line when you perform the above steps, the Sentry Alarm 
Control Terminal will show where the annoying call originated. For more 
information, See “Annoyance Trap with Alarm Control Terminal” on page 29.

Sentry User GuideAnnoyance Trap
Annoyance 
Trap with Alarm 
Control 
TerminalThe operator for the Sentry Alarm Control Terminal can view Annoyance Trap activity 
and also conference with the annoying caller and the receiver of the call. Following is 
the procedure for the Alarm Control Terminal operator.
For general information about using the Alarm Control Terminal functions, See “Using 
Sentry Alarm Control Terminal” on page 3. For information on showing the status 
window, See “Showing the Status Window” on page 12. For information on showing 
the Annoyance Trap feature window, See “Showing Feature Windows” on page 15.
1. If Annoyance Trap is not configured to set off an alarm when an annoying caller is 
trapped, go to the next step. If it is configured to set off an alarm, press F10 (or the 
key assigned by your administrator) to turn off the alarm. See your administrator if 
you are not sure whether an alarm will sound.
2. When an annoying caller is trapped, information about the call is displayed in the 
Annoyance Trap feature window and the status window, as in Figure 4-1 on page 
29. Bring the Annoyance Trap feature window into focus to view information about 
the call. You will see extension numbers and locations for both parties in the call. 
The Class field describes the people on the Annoyance Trap call:
caller - the person who dialed *69 (or the key assigned by your administrator) to 
trap the annoying caller.
source - the annoying caller.
operator - the Alarm Control Terminal operator, if he or she is conferenced into 
the Annoyance Trap call.
The Link field shows the extension with which the party is linked. This is helpful if 
there is more than one Annoyance Trap call.
If your system is configured to include you in a conference with the Annoyance 
Trap call, See “Emergency Conference” on page 23.

Sentry User Guide Executive Override
Chapter 5 Executive Override
Overview
This chapter describes the Executive Override application.
How Executive 
Override WorksExecutive Override is a versatile application that allows you to “override” a two-
party phone conversation to monitor and/or join the conversation from a Dterm 
telephone. 
To use Executive Override, you simply press a D
term function key. Depending on 
how the software is configured, you may also enter a brief access code. 
Note:
Your system may be configured with more than one function key, and you might 
also have more than one access code. Sometimes a combination of the function 
code and access key determine which features of Executive Override you want to 
use. 
After you press a function key and any required access codes, you are prompted for 
the extension number for the person whose call you want to monitor and/or join, 
and are connected to the extension. For more information on using Executive 
Override, see Using Executive Override on page 33.
The following paragraphs briefly describe the various features of Executive 
Override.
Note:
These features are configured and assigned to function keys/access codes by your 
system administrator. If you are not sure which features are available, see your 
system administrator for feature availability and function key/access code as-
signments. 
Override Type
There are three ways to “override” a call after you initiate Executive Override:
Basic - You immediately are connected with the desired extension, regardless 
of whether that extension is busy or not.
Automatic - You are connected to the extension immediately if it is not busy. If 
it is busy, Executive Override waits for a set period of time. If the time expires 
and the extension is still busy, Executive Override interrupts the call and 
connects you to the extension. If the extension becomes idle before the time 
expires, Executive Override connects you immediately.
Monitor - You can silently listen to a conversation, with the option of joining 
the conversation at any time.
Warning Tone
Depending on how you configure Executive Override, a warning tone may sound 
when a person joins a call. The warning tone option is used only with Basic and 
Automatic override types. The warning tone does not sound if you want to monitor 
a call. 
						

							Page 32NDA-30079   Revision 1.0
Executive Override Sentry User Guide
Join Method
Three Way - When you “override” an extension, you join the conversation for a 
three-way call.
Two Way - When you “override” an extension, you are on a two-way call with 
the person whose extension you dialed. The other party is disconnected.
Figure 5-1 lists the possible feature combinations for Executive Override. Your 
system can be configured to use one or more of these feature combinations. A 
unique function key (or function key and access code) is assigned for each feature 
combination.
 
Figure 5-1   Executive Override Options
Override Security
Executive Override contains special security features which limit who may use it 
and how it may be used.
Authorization Code - This is a unique value (up to 10 digits) assigned to 
individuals who are authorized to use Executive Override. Enter this code on the 
D
term when performing an Executive Override. 
Protected Station - A station (telephone) that is designated protected cannot be 
monitored or joined using Executive Override.
Secure Station - A station (telephone) that is secure does not require an 
Authorization Code to use Executive Override.
History Logging
Executive Override provides the ability to log events to UNIX files and/or printers. 
See your system administrator and the Sentry Alarm Control Terminal Installation 
Guide for more information.

Using Executive Override
The following procedures are examples of how you can use Executive Override.
Basic OverrideIn this example, you are using a non-secure phone that requires an authorization 
code. You will use the Basic Override feature to join a conversation for a three-way 
call. The person at the destination extension is already in conversation with another 
party. A warning tone will let the parties know you are joining their conversation. 
From a Dterm phone
1. Press the function key assigned for a basic three-way override with warning 
tone. The function key lights up and the LCD display gives the following 
prompt:
ENTER AUTH #
2. Use the Dterm keypad to enter your authorization code, and press #. The LCD 
display gives the following prompt:
ENTER DEST #
3. Use the Dterm keypad to enter the destination extension number, and press #. 
The LCD display gives the following prompt:
PLEASE ANSWER
4. Answer your phone. The parties you are joining hear the warning tone, and you 
are connected with the call. The LCD display will show the following to indi-
cate the conference call:
CNF

Executive Override Sentry User Guide
Automatic 
OverrideIn this example, you are using a non-secure phone that requires an authorization 
code. You will use the Automatic Override feature to join a conversation for a two-
way call. The person at the destination extension is already in conversation with 
another party, but you wish to speak only with the person at the destination 
extension. There is no warning tone. 
From a Dterm phone
1. Press the function key assigned for an automatic two-way override with no 
warning tone. The function key lights up and the LCD display gives the follow-
ing prompt:
ENTER AUTH #
2. Use the Dterm keypad to enter your authorization code, and press #. The LCD 
display gives the following prompt:
ENTER DEST #
3. Use the Dterm keypad to enter the destination extension number, and press #. 
The LCD display shows this message:
CAMP ON
4.  Since the destination extension is busy, Executive Override waits a designated 
number of seconds and repeatedly calls the extension. After the designated 
number of seconds, the destination extension is disconnected from its current 
call (with no warning tone) and you are connected to the destination extension. 
The LCD display gives the following prompt:
PLEASE ANSWER
5. Answer your phone. You are connected with the person at the destination exten-
sion.
