NBX hardware needs no routine maintenance. However, you should
perform periodic backups of the configuration and license databases,
especially after you make changes to system or user configurations.
Each NBX Telephone supports a telephone diagnostic and configuration
utility called the Local User Interface (LUI). The LUI utility enables you to
perform these tasks:
View telephone settings, both the active settings and the settings
stored in the telephone's memory
Set telephone IP address, subnet mask, and default gateway
Specify IP address of the Network Call Processor (NCP)
Test the telephone buttons, display panel, and LEDs
Clear all device settings
Specify the MAC address of the NCP (test environment option)
View firmware information (technician option)
