Chapter 8: Telephone Management and
Troubleshooting
Introduction
The 4600 Series IP Telephones are relatively trouble free. This chapter provides helpful
information for:
● Interpreting the different ringer tones you hear.
● Interpreting the 4620’s display symbols.
● Testing your telephone to ensure that 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.
Additionally, Chapter 6: 4620/4620SW/4621SW IP Telephone Options
describes several status
screens to use to troubleshoot certain problems, as requested by your System Administrator.
For all other IP telephone questions or problems, contact your System Administrator.
Interpreting Ringer Tones
As you become more familiar with your IP telephone, you will recognize the various tones you
hear in response to an incoming call or while using the handset. The following chart provides an
overview of the tones you hear. Check with your System Administrator to verify if the
descriptions are accurate for your system. Ringing Tones accompany an incoming call.
Feedback Tones are those which you hear through the handset (receiver) or the Speaker.
Note:
Note: The PBX, not the telephone, generates these tones, which can differ from this
list. This difference is especially true when the PBX is outside the United States.
