1. A method of exchanging facsimile data between a local station and a remote station, with each of said local and remote stations having facsimile capability and video capability, comprising the steps of:

  • generating modulated facsimile data in response to operation of a first facsimile machine that is located in physical proximity to the local station;

    receiving the modulated facsimile data at an interface module coupled to a video conferencing system of the local station, the modulated facsimile data being generated by the first facsimile machine from a document to be imaged;

    demodulating the facsimile data so as to form digital facsimile data;

    formatting the digital facsimile data into packets, including selecting between formatting the digital facsimile data into facsimile-directed packets for imaging the document via a second facsimile machine at the remote station and formatting the digital facsimile data into video-directed packets for imaging the document via a video conference screen in physical proximity to the second facsimile machine at the remote station;

    automatically injecting the packets of digital facsimile data into a digital video stream carrying video conference data bound for the remote station;

    receiving a data stream at the local station from the remote station, including receiving video data from the remote station; and

    selectively converting a portion of the video data received from the remote station into facsimile data and forming a facsimile image of the converted portion of video data at the first facsimile machine.
