Call waiting
If you have enabled call waiting for your station (PROG/HELP 3 1) and a second call comes in while you are
on another, you’ll hear a tone in your earpiece and the bottom line of your display will indicate that a second call
is waiting. You can ignore the call waiting and it will be transferred to your mailbox (or other destination set by
the Installer).
To toggle between the two calls on a 48-Key or 24-Key Feature Phone, press FLASH. To drop either call,
press RELEASE while connected to the call to be dropped: this disconnects the call and automatically re-connects
you to the other call.
On a 12-Key Digital Feature Phone, press the hook switch quickly to toggle between two calls (FLASH), or hold
the hook switch down to release the call (RELEASE).
Call waiting display
Be sure to check the display when you’re using call waiting. Initially, the first line shows the name or number
of your original call (depending on how the call was created) and the call duration. The second line shows the
name or number of the call waiting along with the duration of that call. The arrow on the display will move
between the first and second lines, indicating to which call you are connected.

Here’s an example:
1. You’re connected to XYZ Company, when you hear a beep and see that Joe Smith is calling:
Cordless
Handset or
24-Key
Feature Phone
48-Key
Feature
Phone
(In this example, Joe’s call is being transferred to you; it’s been in the system for 31 seconds.)
2. You press FLASH and are connected to Joe. Note how the arrow moves to indicate the change
of connection:
Cordless
Handset or
24-Key
Feature Phone
48-Key
Feature
Phone
Note: If Caller ID is not used, the Line number will appear instead of the caller’s name or number. If Caller ID is
used, in some instances the local telephone service provider will only show a general caller status such
as Unavailable, Private, or No Data Sent.
Station-to-station call waiting
You can call, or transfer a call to, another station that is in use (as indicated by the fact that its station key, if
one exists for it on your ESI Feature Phone, is glowing red). This generates a call waiting tone in the other
station’s earpiece and puts a call waiting indication on the bottom line of that station’s display, as explained in
“Call waiting display” (above). If the person ignores the call waiting, your call or the transferred call will be
forwarded to the person’s mailbox (or other destination set by the installer).

A 12-Key Feature Phone will show only the first caller. Even if you hang up from the first call, the second call’s Caller ID information will not appear.
