Network Quality

The quality of the Model 8602 voice transmission, like that of any other device trans-
mitting on a data network, is dependent on several variables. These variables can
include the speed and capacity of the network configuration, type of connection, rout-
ing 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 optimum 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
Model 8602 may not connect to call processing 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.
