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.

Callback 5 - 5
