Abstract: A method for using a telephone system, in order to replace the use of existing mail systems, for sending out certified or registered information. The receipt of such information is acknowledged and responded to by use of this method. The method involves initiating the call, recording the substance of certified or registered information, prompting a pre-recorded announcement as soon as the communication is made in order to advise the recipient that the call is being recorded along with the time and date of the call. After the announcement, the pre-recorded information is transmitted, a record is made of the response, if any, and a full record, including time and date is sent to the initiator of the call. Alternatively, the "certified" information is spoken by the initiator, rather than being pre-recorded.
