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.

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