Troubleshooting
335
This chapter provides an administrator with general information for troubleshooting
some common problems that he (or she) may encounter while using CP860 IP
conference 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
problems and fix them.
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
If your IP phone encounters some problems, commonly the log files are needed. 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
(Changes to this parameter via web user interface require a reboot).
In the configuration files, you can use the following parameters to configure system log
settings:
 syslog.mode – Specify the system log to be exported to a server or local system.
 syslog.server -- Specify the IP address or domain name of the syslog server to
which the log will be exported.
 syslog.log_level -- Specify the system log level. The following lists the log level of
events you can log:
0: system is unusable
1: action must be taken immediately
2: critical condition
3: error conditions
4: warning conditions
