Inter-Tel® Model 8602 User Guide
Environmental Factors
For optimal sound quality, use a headset and read the following guidelines. Optionally, you
can use your computer speakers and microphone, but make sure to use a microphone with
echo cancellation.
Headset Recommendations
The Model 8602 has been designed to work with standard computer headsets. Computer
headsets come in two basic configurations: analog (which use the 1/8-inch mini phono
jacks on the computer sound card interface) and digital (which use the USB interface). In
general, USB headsets are known to produce higher-quality audio because they send
digital audio to the computer and may have other built-in features, such as echo
cancellation. User satisfaction for any particular headset can be quite subjective, so InterTel recommends that you try before buying so you are more likely to be satisfied with the fit,
quality, and cost of the solution. This recommendation inclu des all wired/wireless headsets,
including the integrated Plantronics CS50-USB Wireless Headset.
In addition, Inter-Tel recommends using a headset with a built-in microphone to avoid audio
feedback (echo). Optionally, you can use your computer speakers and microphone, but be
sure to use a microphone with echo cancellation. When using a headset, plug in the
headset before starting the Model 8602 application.
Wireless Considerations
To operate, the Plantronics CS50-USB Wireless Headset must remain within the system’s
range operating limit from the base. Refer to the Plantronics CS50-USB Wireless Headset System User Guide for more details. Contact your local Inter-Tel provider for the user
guide.
Inter-Tel® Model 8602 User Guide15
Volume Controls
To control audio quality and/or feedback problems, adjust the computer’s audio controls.
For example, lowering the speaker volume and the microphone gain may help solve certain
echo problems. The Model 8602 allows you to increase or decrease the volume for the
microphone and speaker through the Main Display of the Model 8602 interface. See the
“Main Display” on page 20 for details.
T o adjust the speaker and microphone volume on the interface:
Select the volume slider for the microphone or speaker and drag to increase or
decrease the volume.
To adjust the speaker volume using the Plantr onics CS50-USB Wireless Headset:
Adjust the volume using the Volume Control on the headset. Refer to the Plantronics
CS50-USB Wireless Headset System User Guide for more details.
You can also adjust the speaker and microphon e volume in the Windows
volume control application.
NOTE
If you are having problems with the volume level while using the Plantronics
CS50-USB Wireless Headset, and you have made all the necessary
adjustments on the Main Display and in the Windows settings, you can also
use the earloop that comes with the headset for optimal sound.
Muting the Microphone
If you are using a headset with a microphone, it is possible that you will still get some echo
(audio feedback).
T o mute or disable the microphone on the interface:
While on a call, click the Microphone icon on the Main Display of the Model
8602. The mute icon appears .
T o mute or disable the microphone using the Plantronics CS50-USB Wireless
Headset:
While on a call, press and release the Volume Control button on the headset. Refer
to the Plantronics CS50-USB Wireless Headset System User Guide for more details.

Inter-Tel® Model 8602 User Guide
Network Quality
The quality of the Model 8602 voice transmission, like that of any other device transmitting
on a data network, is dependent on several variables. These variables can include the
speed and capacity of the network configuration, type of connection, routing scheme, and
amount of traffic being passed through the network. Inter-Tel has used the latest
technologies to ensure the best possible quality in all circumstances.
Under optimal conditions, voice quality will not be affected. However, heavy traffic, complex
routing schemes, or poor network connections may cause a degradation in voice quality
(distorted sound or choppy audio) or cause delays in transmission.
Firewall
You may be running a firewall on the computer where you will be running the Model 8602.
Windows XP has built-in firewall protection. If the Windows built-in firewall or other software
firewall, such as ZoneAlarm
to the telephone system or you may not hear audio. You need to make sure the Model
8602 software application is added to your firewall as an excepted application so it can
receive information from the network.
To configure your Windows XP firewall:
1. Select Start – Control Panel – Windows Firewall.
2. In the General Tab make sure “On (recommended)” is selected. This enables the
Windows built-in firewall protection.
3. Click the Exceptions tab and make sure Inter-Tel 8602 is selected under Programs
and Services. The Windows firewall will not block incoming network activity from the
telephone system so the Model 8602 can operate.
If you are using a software firewall program such as ZoneAlarm, you want to make sure the
Model 8602 is added to the “Exceptions” or “Allowed” list. The destination IP address may
need to be added to the firewall’s “Trusted Zones.” Refer to the manufacturer’s
documentation for information on configuring your application.

Emergency (E911) Call Information
When the installation wizard is run, a screen appears with the information below on
emergency 911 (programmed default number for US Inter-Tel telephone systems) or 999
(programmed default number for European Inter-T el telephone systems). You must select “I
agree” to continue with installation of the IP softphone. This message also appears each
time you initiate and run the IP softphone.
NOTE
Select “never show this dialog again” in the emergency 911 dialog box to
prevent this dialog from appearing when you start the application.
E911 Warning
Do not dial emergency hotline numbers from the IP softphone.
NOTICE
In the case of an emergency, dial the appropriate local emergency-service number
directly, or use the nearest local public phone to dial an emergency hotline (911, the
default setting programmed in US Inter-Tel telephone systems or 999, the default setting
programmed in European Inter-Tel telephone systems).
The IP softphone communicates through a central telephone system that routes all
emergency calls directly to a number that is local to the central system. If the IP
softphone is not at the same address as the central system, then emergency service will
not be routed to the proper locati on .
Therefore, if the IP softphone does not stay within the premises of the central system, you
must configure the IP softphone’s programmable keys to dial the local police or fire
departments directly, and you must clearly label the key icons. If the IP softphone is
mobile, meaning it is used in multiple locations, you must know the direct emergencycontact numbers for each location and program them accordingly as programmable
buttons.
In the case of an emergency, you are responsible for determining the nature of the
emergency and dialing the appropriate emergency-service number directly. You must
provide the emergency personnel your location and telephone number because the
emergency service may not receive accurate identification information automatically.
The Model 8602 Interface
Before starting the Model 8602, you should learn about the parts that comprise your IP
softphone. The different parts of the Model 8602 provide access to several features.

About Voice Mail
Voice mail is an application that is part of the Inter-Tel voice processing system. Using
voice mail, you and other callers can send and receive recorded messages from any
supported endpoint on the system. To use voice mail features, each user (or subscriber) is
assigned a mailbox, which usually corresponds to the extension number assigned to your
endpoint. You can, however, have an unassociated mailbox that does not correspond to an
extension. (Unassociated mailboxes are typically used for agents or other personnel who
don’t have a permanent office.)
With your mailbox, you can use personal or system greetings to let callers know if you are
out of town, on a call, etc. If a caller reaches your mailbox, they can leave a message, hang
up, or access an attendant.
Inter-Tel voice mail systems support the following types of mailboxes:
• Advanced Mailbox: If E-Mail Reader is enabled for your mailbox, you have an
advanced mailbox and access to voice mail, e-mail, and fax messages in your
mailbox. You can also customize your personal mailbox options, and acce ss
advanced messaging features. For a voice mail flowchart for advanced mailbox users,
see “Voice Mail Flowchart (Advanced)” on page 43.
• Standard Mailbox: This type of mailbox allows you to send and receive voice mail
messages, record personal greetings, and customize personal mailbox options. A
standard voice mailbox does not allow you to access e-mail and fax messages. For a
voice mail flowchart for standard mailbox users, see “Voice Mail Flowchart (Sta ndard)”
on page 44.
Depending on the voice mail system, you may also have access to advanced
communication and messaging features such as E-Mail Reader and Automatic
NOTE
Speech Recognition (ASR). For more information about these features, refer to
the Model 8662 User Guide (part no. 550.81 17). You can find this user guide on
Inter-Tel’s Web site at www.inter-tel.com.

The instructions for many voice mail tasks are identical for standard voice mailbox and
advanced mailbox users. The instructions for the basic mailbox tasks are included in this
User Guide. For advanced mailbox features, refer to the Model 8662 User Guide (part no.

are caused by setting the microphone
volume too high. Also adjust the
headset speaker volume such that
the far end speaker is audible, but not
so loud that the audio out of the
