Abstract

A system that provides supporting software to allow facsimile documents to be transferred via non-traditional mechanisms such as electronic mail, the Internet, and V.32 or other non-fax modems. The system allows facsimile documents to be transferred by computer without intermediate G3 facsimile hardware and without performing time-consuming compatibility determinations. The system also provides for cross-platform document transmissions.
