Abstract
Abstract A local telephone/radio paging system includes a local paging system, a telephone, and a memory for indicating which telephone numbers are within the local area. When a telephone number is dialed, if the person dialed does not answer, the telephone switching equipment checks the memory to determine whether the dialed number is within the local paging area. If so, a local paging transmitter is activated, paging the person assigned to the unanswered phone. Such a paging transmitter may be included in each phone, or a single central local transmitter may be employed. The paging receivers desirably include alphanumeric displays and indicate the number of the telephone that originated the unanswered call, so that the person carrying the paging receiver may call back immediately.
