ESI Feature Phone operation
Display
When your phone (or station) is not in use, the display will show the current date and time, activated
features such as DND (do not disturb; see “MUTE/DND,” page E.3), monitor mode, etc.), and — on a
24-Key or 48-Key Feature Phone — the system’s current line usage. The line usage display you see will
depend on (a.) how many lines you have and (b.) which Feature Phone that you’re using.
• If your system has a smaller number
of lines (18 or fewer if you’re using a
48-Key Feature Phone; 16 or fewer if
you’re using a 24-Key Feature Phone),
each block on the bottom line of the
display will represent an individual line
(as in the examples, right). Incoming calls
usually are assigned beginning with
Line 1 at the far-left line indicator.
Outgoing calls are assigned from the
highest numbered line beginning at the far right.
• If your system has a greater number
of lines (19 or more if you’re using a 48-
Key Feature Phone; 17 or more if you’re
using a 24-Key Feature Phone), the
bottom line of the display will provide an
approximate representation of the lines
in use (shown at right).
As you use your ESI Feature Phone,
its display changes frequently to give
you detailed information during call
processing and voice mail operations.
Caller ID
If you subscribe to Caller ID from your telephone service provider, the phone’s display will show an
outside caller’s name and/or number.

In some instances, the service provider can send only a general
caller status — such as UNAVAILABLE, PRIVATE or NO DATA SENT.

If you don’t subscribe to Caller ID, the LCD will show which line is receiving the call, instead of the caller’s name or number.
