Call Transfer if busy
A subscriber B can hand over a call with subscriber A to the busy subscriber C
after making an enquiry call to C by activating a recall and then hanging up. As
soon as the busy subscriber C is free again, C's set will automatically ring. When
C answers, he is connected with A.
