Ethereal or Wireshark software to capture the packets. You can also set a mirror port in
the switch to monitor the port of the connected IP phone.
The IP phone provides a troubleshooting feature called “Watch Dog”, which helps you
monitor the IP phone status and provides the ability to get stack traces from the last time
the IP phone failed. When the Watch Dog feature is enabled, the IP phone will
automatically reboot when it detects a fatal failure. This feature can be configured using
the configuration files or the web user interface.
You can use the “watch_dog.enable” parameter to configure the Watch Dog feature in
the configuration files. For more information, refer to
on page
To configure the Watch Dog feature via web user interface:
1.
Click on Phone->Preference.
2.
Select the desired value from the pull-down list of Watch Dog.
3.
Click Confirm to accept the change.
In some cases, the status indicators consist of power LED, message key indicator, line
key indicator, headset key indicator and the on-screen icon/error messages, which are
useful for you to figure out the cause of your phone’s failure.
