ABSTRACT:
A voice Telephone Network Applications Platform (NAP) is enhanced to manage facsimile messages, as well as voice messages, by the addition of facsimile functionality to the platform actuatable by high-level facsimile commands from applications supported on the platform. The commands include sending and receiving facsimile messages. A PC facsimile processor (FP), interfacing between the platform and the telephone network, stores facsimile messages received from the network and facsimile messages for transmission to the network on hard disk. A facsimile command from an application is expanded into NAP commands for controlling the platform and FP commands for controlling the facsimile processor so as to perform the facsimile functionality associated with the facsimile command. A recovery process utilizing a Recovery Token prevents facsimile messages from becoming lost between receipt at the FP and storage in the platform.
