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.

Detailed Description
Tab. 2.178: Call transfer if busy
If subscriber B signals call waiting to C and then goes on hook, the call with A is
transferred. This applies only if C does not reject B’s call. For the full scope of this
feature see "Call waiting", page 477.
If the call is not answered by C within the configured recall time (C still busy or
does not answer), B again obtains ringing (see "Recall", page 472).
