ABSTRACT:
A communications system is designed to present a number of options to a caller who is attempting to reach a call-waiting subscriber already busy on a first call. The options are presented to the caller via an announcement that offers the caller the alternative of either sending immediately a conventional call-waiting alert signal to the subscriber, or leaving a message that is automatically delivered to the subscriber immediately after the subscriber terminates the first call.
