ABSTRACT:
Messages are routed via a cellular communications network to multiple cellular communications receivers configured for answering calls placed to a common subscriber number, such that a message originated with a single cellular call may reach multiple recipients. The geographic area of message distribution may be controlled by selectively enabling different cell sites for calling particular subscriber numbers. The cellular receivers may have message storage capabilities for subsequent replay of received messages. Message storage may be provided by downloading messages to a conventional telephone answering device also connected for landline telephone call answering, thereby adding received cellular messages to recorded landline telephone messages.
