Features

When you reach a busy extension. or the outside line you want
to use is busy, use Callback to place the call automatically
when the extension or line is free.

You’ll hear a priority ring-me long ring and three short

rings—as soon as the extension or line is free. The call is
placed when you lift the handset or press Speaker.

On phones with ICOM  buttons, Callback works only for busy
inside extensions; use Line Request for busy outside lines.
(See Line Request.) On phones with  SA buttons, Callback
works with busy inside extensions; it works with busy outside

lines when you are using an SA or Pool button.

Callback works only when the outside line you want to use is
busy, which is indicated by a fast busy signal. Callback does

not work when the outside phone you call is busy, which is
indicated by a normal busy signal.

You can use Callback either selectively or automatically:

■

Selective Callback  is activated, on a per call basis,

when you dial the feature code or press a programmed
button.

■

Automatic Callback  is activated every time you reach
a busy extension or, if your phone has SA buttons, a
busy outside line. You need to program your phone for

Automatic Callback.
