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.4), 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.
Note: An ESI Cordless Handset's display is similar to that of the 24-Key Feature Phone; one difference is that a
Cordless Handset doesn't show line usage.
• 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.
If you have a 48-Key or 24-Key Feature
Phone (see pages A.2–A.4), it may come
with an available backlit display, for higher
readability under a wider variety of lighting
conditions. (No adjustments can be made
to its contrast or brightness.)

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.
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.
