On-hook dialing

German: Wählen mit aufliegendem Hörer.

Explanation
Condition: the hook is on the telephone (idle mode). If you enter a number on the phone and then either take the hook off or press the OK button the result will be that in both cases the number is being sent and a connection is being built up (in case the number is correct).
