  • Patent number: 4939771
    Abstract: A Call Message Delivery system (CDS) enables an attendant to control the delivery of a recorded call message from a caller to a specified party at a called station. The CDS alerts the attendant at a delivery time, selected by either the caller or the system. When the attendant determines that the specified party has answered the call at the called station, the caller's recorded call message is outputted to the specified party. If the specified party is not available, the attendant may schedule the call for a later delivery or may forward the call to another station specified by the answering party at the called station.
