IP Deskphone diagnostics
Network-related issues can be debugged using the Network Diagnostic Utility (NDU) built into
the IP Deskphone.
Another way to diagnose a problem on an IP Deskphone is to capture a message trace using
any appropriate software.
The IP Deskphone has Problem Determination Tools (PDT). These can be accessed through
a Telnet session using the IP address of the IP Deskphone (for login and password, contact
Avaya).
