3.3.2Automatic callback on busy

The ISDN connection of a party you have called is busy. However, you want to urgently speak to this person. In this case, you activate the "Automatic callback on busy" function by pressing the redial key (w) after receiving the busy tone (pay attention to the acknowledgement tone) and by then hanging up. As soon as the busy connection is free again, the callback is signalled to you. When you lift your handset or press the loudspeaker key, the person who has now become free is called automatically.
