ABSTRACT:
Printed or other pre-formed documents are delivered to requesters rapidly and at low cost by a microcomputer-based system which uses voice generation circuitry to invite a person calling in to the system to specify the document needed by pushing particular keys of his/her touch-tone telephone. Upon ascertaining the identity of the document in question, the computer transmits the document to the caller in standard facsimile form, either over the telephone connection already established if the telephone call was initiated from a telephone connected with a facsimile machine, or to a different telephone number specified by the caller.
