ABSTRACT:
Microelectronic, locally-situated circuitry and memories, together with digital displays, are employed for modifying otherwise standard telephone stations so that the telephone stations can be utilized to store digital messages, such as the Caller's telephone number, transmitted by each of a plurality of Callers to an unattended User station. The unattended User station automatically retransmits a received digital message back to the Caller for verification, permitting the Caller to correct any error in the digital message or to send to the User station a verification signal that is also stored. All the stored information is available to the User upon his return, and may be used to automatically dial back the Callers.
