Callback
When you reach a busy extension or outside lines are busy,
use Callback to automatically place the call when the
extension or a line is free.
You’ll hear a priority ring (three short rings) when the
extension or a line is free. The call is placed automatically
when you lift the handset. You can use Callback for only one
call at a time.
Callback for outside calls works when the outside line you
want to use is busy, as indicated by a fast busy signal.
Callback does not work when the outside telephone you call
is busy, as indicated by a normal busy signal.
Depending on how your telephone is set up, you can use
Callback either selectively or automatically:
You use
Selective Callback
by dialing the feature
code.
Automatic Callback
is set up for your phone at
installation or by your system manager. Every time you
call a busy extension or try to get an outside line that is
busy, your call receives Callback treatment. (If
Automatic Callback has been set up for you, you
cannot turn it off.) When Automatic Callback is on, you
cannot use Selective Callback.
