Administrator's Guide for SIP-T2_Series_T4_Series IP Phones
To capture packets using the Ethernet software:
Connect the Internet port of the IP phone and the PC to the same HUB, and then use
Sniffer, Ethereal or Wireshark software to capture the signal traffic.
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. If 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 via web user interface.
You can use the "watch_dog.enable" parameter to configure watch dog feature in the
configuration files.
