This chapter provides an administrator with general information for troubleshooting
some common problems that he (or she) may encounter while using SIP-T4X IP phones.
IP phones can provide feedback in a variety of forms such as log files, packets, status
indicators and so on, which can help an administrator more easily find the system
problem and fix it.
The following are helpful for better understanding and resolving the working status of
the IP phone.

Viewing Log Files

Capturing Packets

Enabling the Watch Dog Feature

Getting Information from Status Indicators

Analyzing Configuration Files
The IP phone can log various events to log files. So if your IP phone encounters some
problems, commonly the log files are used. You can export the log files to a syslog
server or the local system. You can also specify the severity level of the log to be
reported to a log file. The default system log level is 3.
In the configuration files, you can use the following parameters to configure system log
settings:

syslog.server -- Specify the IP address of the syslog server to which the log will be
exported.

syslog.log_level -- Specify the system log level (Changes to this parameter via web
user interface require a reboot).
For more information on the system log setting configuration parameters, refer to Log
Settings on page 385 .
To configure the system log level via web user interface:
1. Click on Settings->Configuration.
