Call transfer if busy

A user B can hand over a call with user A to the busy user C after making an enquiry
call to C by activating a recall and then hanging up. As soon as the busy user C is
free again, C's phone automatically begins to ring. When C answers, he is connec-
ted with A.

For users in the public network or reached via the public network, the feature Callback if busy (CCBS) must
be supported end-to-end by the public network.
If user B signals call waiting to C and then goes on hook, the call with A is transfe-
rred. This applies only if C does not reject B's call. For the full scope of this feature
see "Call waiting", página
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
