The feature key label area displays a 10-character string for each of the feature keys. Each feature key includes the key label and an icon. The icon state can be on, off, or flashing. A telephone icon displays the status of the configured DN. Key labels are left-aligned for keys on the left side of the screen, and right-aligned for keys on the right side of the screen. To change the feature key label, press the Services key to access Telephone OptionsChange Feature key label option. For more information about changing the feature key label, see the applicable IP Deskphone User Guide.

If a label is longer than 10 characters, the last 10 characters are displayed, and the excess characters are deleted from the string.

The endpoint requires localized data for the stations:

Localization is at least partially outside the scope of the Device Adapter in this respect, as the custom labels are administered on the System Manager and passed down to the Device Adapter and endpoint. A Unicode label can successfully be sent to any station that has the correct firmware; sending a Chinese label, for example, to an endpoint whose firmware does not support Chinese will not work. Endpoints supporting Chinese have a reduced number of call information lines, allowing them to use “taller” characters. However, a custom label in Chinese may be loaded on a station that supports the Chinese language.
