Labeling
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-20L telephones, and this information can also be
programmed by the user at the extension.
Posted message 01,
2.0. Starting with Release 2.0, when an MLX user activates the Do Not
Disturb feature, the Do Not Disturb message is automatically posted.
Therefore, in Release 2.0 and later, this posted message is not allowed
to be changed. (The message may be posted even if the user does not
activate Do Not Disturb.)
An alphanumeric label can be assigned to the calling group. The label
is displayed when a group member answers a group call or when an
MLX display telephone user presses the Inspct 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, affecting both the system and the
applications.
The labels stored in the Extension Directory appear on MLX display
telephones when users send each other messages. Messages include
the name (the 7-character label) of the user who sent the message and
the time and day the user called. Posted messages are created and
changed by using Labeling.
Labeling is used to enter the telephone numbers and label information
associated with System Speed Dial codes.
