ABSTRACT:
Described is an automatic paging system that will alert a paging service subscriber to the occurrence of specific events at a remote location using a standard home type answering machine and/or a standard alarm system. The paging system works in conjunction with existing paging subscription services and answering machines presently available. The system detects if a valid message has been left on the answering machine or if an alarm has been tripped, then dials a number that the user programs into the system that corresponds to the paging service telephone number, then waits for an acknowledgment tone from the paging service and dials a distinct code that corresponds to what has occurred at the remote location. The system will forward a telephone number to the paging service subscriber, if such a number has been entered into the answering machine by a caller.
