If a label is assigned to the extension, the 4400-Series or MLX telephone user sees the label, the extension number, and the posted message, for example, STEVE B Ext 7101 OUT TO LUNCH. If a label is not assigned to an extension and a caller dials that extension, the telephone's extension number is displayed (instead of the user's name), along with any posted messages. For example, a 4400-Series or MLX display telephone user sees Ext7103 OUT TO LUNCH.
If labels have not been assigned to operator extensions, display telephone users see OPERATOR and the operator's extension number when receiving a call from the operator.
If labels have not been assigned to outside lines/trunks, display users see the factory-set label, OUTSIDE and the line/trunk number (such as Trk810), when an outside call is made or received. With AT&T's PRI-ANI service, another PRI calling party number service, or Caller ID service and an 800 GS/LS-ID, 408 GS/LS-ID-MLX, or 412 LS-ID-TDL module (loop-start lines only), the caller's number is displayed (4400-Series, MLX, ETR, and MLS display telephones). If you use PRI service of any kind, you must have a 100D module. To use Caller ID, you must have loop-start lines. AT&T's PRI-ANI service provides only the caller's number. You can view both number and name, but not simultaneously.

The availability of the caller identification information may be limited by local-serving (caller's) jurisdiction, availability, or Central Office equipment. Except for the 4400D telephone, programmed labels cannot be shown on nondisplay telephones or on single-line telephones. |
Labels that are programmable by a user are displayed in all capital letters.
Labels can contain capital letters, numbers, and eight types of characters: ampersands (&), dashes (-), spaces, periods (.), commas (,), apostrophes('), asterisks (*), and pound signs (#).
