When the caller makes a call to a busy or an unanswered internal telephone, the system calls the caller when the called party becomes available. Upon hearing the busy signal, the caller activates the Automatic Callback feature and disconnects the call. The system monitors the called party. When the called party becomes available to receive the call, the system automatically initiates the Automatic Callback call. The caller receives priority ringing. The caller then lifts the handset, and the called party receives the same ringing that the system provided on the originating call.

For example, Station A calls Station B. Station B is busy or not answering. Station A sets the Automatic Callback feature. When Station B becomes available, the system will call Station A. This is ringout call. The system does not present the ringout call to Station A pickup group or bridges. Once Station A answers, the system rings Station B. This is callback call. Callback call is like a normal call made to Station B and can be picked up by Station B pickup group or bridges.

To activate the Automatic Callback feature, the user of a single-line telephone presses the Recall button, or flashes the switchhook. The user then dials the Automatic Callback Feature Access Code (FAC). A single-line user can activate Automatic Callback for only one call at a time.

If the original caller answers an Automatic Callback call, and for some reason the called extension cannot accept the Automatic Callback call, the caller hears a confirmation tone and then silence. The call is still queued.

Users cannot activate Automatic Callback for calls to:
