Callback
When you reach a busy extension or the outside line you want
to use is busy, use Callback to automatically place the call
when the extension or line is free.
You’ll hear a priority ring---one 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 only when you are using a
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 select Callback from the Feature screen, 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.
