Administrator's Guide for SIP-T2 Series/T4 Series/T5 Series/CP920 IP Phones

Watch Dog

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 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 via web user interface.

Network Diagnostics

You can use ping and traceroute diagnostics for troubleshooting network connectivity via the web user interface or
phone user interface.
You can also enable the phone to detect the reachability of the connected wired or wireless network via auto pro-
visioning. The phone can display an icon warning (for T42S/T41S IP phone, prompt a message) on the phone screen
when the network is unreachable. You can set the time interval for network reachability detection.
