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 2.345.
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 2.340).
If subscriber B intrudes on C's call and then goes on-hook, the call with A is also
transferred. This applies only if C neither rejects nor answers B's call. For the full
scope of this feature, see "Intrusion", Page 2.349.
