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/T42U/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.
