Management and Troubleshooting
Overview
The 4620 IP Telephones are relatively trouble-free. This chapter provides
helpful information for:
• Testing your telephone to be sure it is operating correctly.
• Basic Troubleshooting; this chart provides the most common
problems an end user might encounter and suggested resolutions.
• Application-specific troubleshooting; this chart describes problems
and solutions specific to a 4620 application (Phone, Speed Dial,
Call Log, or Web Access).
• Resetting or power-cycling your phone, when Basic Troubleshooting
does not resolve a problem.
Testing your phone
This test function enables you to verify that your telephone’s lights and
display are operating properly.
Testing the Telephone's Lights and Display
1. With the telephone idle (on-hook), press and release the Mute
button, then press the following numbers on the dialpad: 8 3 7 8 #
(which stands for TEST).
• The display should indicate the self-test has started. If the test
is successful, the message “Self test Passed #=end” displays; if
the test is not successful, the message “Self test Failed #=end”
displays instead.
2. Press # to return to the Phone screen.
• If nothing appears on the display and the phone is receiving
power, your phone may need to be replaced. Contact your
System Administrator for assistance or additional
troubleshooting information.

Problem/Symptom Suggested Solution
Phone does not activate when
connected for the first time.
Unless your System Administrator has
already initialized your telephone, you
may experience a delay of several
minutes before it becomes operational.
Upon plug-in, your telephone immediately
begins downloading its operational
software, its IP address, and any special
features programmed by your System
Administrator from the server to which it is
connected. Report any delay of more than
10 minutes to your System Administrator.
