Chapter 5: Troubleshooting Guidelines
Introduction
This chapter describes problems that might occur during 4600 Series IP Telephone operation
and possible ways of resolving these problems.
Error Conditions
Table 14: Some Error Conditions in Operation of 4600 Series IP Telephones identifies some of
the possible operational problems that might be encountered after successful 4600 Series IP
Telephone installation. Possible installation problems and how to conduct a telephone self-test
are discussed in the 4600 Series IP Telephone Installation Guide’s “Troubleshooting” chapter.
The User Guides available on the Avaya support Web site also contain guidance for users
having problems with specific IP telephone applications.
Note:
Note: Most of the problems reported by 4600 Series IP Telephone users are not likely
to be problems with the telephone itself. Problems are more likely LAN-based,
where Quality of Service, server administration, and other issues can impact
end-user perception of IP telephone performance.
Most error conditions are related to network problems, and are common to both
SIP and H.323 telephones. Unless otherwise stated, the error conditions and
messages covered in this chapter apply equally to both telephone types (H.323
and SIP).
