  • Electronic facsimile document transportation system utilizing local exchange carriers and a wide-area network
    Patent number: 6618165
    Abstract: An Internet-based electronic facsimile document transmission and reception system accommodates conventional facsimile (fax) machines and uses store and forwarding rather than real-time facsimile transmission to avoid keeping the originating fax machine (and the telephone line to which it is attached) from being unnecessarily occupied due to delays associated with the Internet. The preferred embodiment also obviates the need for PBXs at the fax machine ends of the system.
