This chapter provides an administrator with general information for troubleshooting 
some common problems that he (or she) may encounter while using 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 Watch

 

Dog Feature

 

 

Getting Information from Status Indicators

 

 

Analyzing Configuration File

 

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. 

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 

5: normal but significant condition 

6: informational
