Labeling is used to enter the names of the persons or
businesses associated with the System Speed Dial numbers
stored as listings in the System Directory. It is also used to
enter the names of people, groups, and locations associated
with the extensions in the system stored as listings in the
Extension Directory. Labeling is used to enter the telephone
numbers and label information associated with Personal
Directories on MLX-20 telephones.
Posted message 01, Do Not Disturb, was changeable before
Release 2.0. Starting with Release 2.0, when an MLX user
activates the DND feature, the DND message is automatically
posted. Therefore, this posted message cannot be changed in
Release 2.0 and later.
An alphanumeric label can be assigned to the calling group.
The label is displayed when a group member answers a group
calling call or when an MLX display telephone user presses the
Inspect button and an Auto Dial button programmed with the
calling group’s extension number.
Extension, trunk, and calling group labels are shared with
certain applications. The extension labels may be entered or
updated in Integrated Administration for both the switch and the
applications.
