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
