Abstract
A system and method for communicating screen display images on a computer to another computer using a telephony network. A screen share button on a data network telephone initiates a screen shot request to a first computer associated with the data network telephone. The first computer uses a screen shot application to retrieve the image on the computer display and send it to the data network telephone. The data network telephone receives the screen shot image and sends the image to another data network telephone which is a party to a telephone conversation with the first data network telephone. The first data network telephone preferably uses the SIP invite with a session description protocol that permits the transfer of image data on SIP messages. The second data network telephone implements the image data session description protocol and communicates the screen shot image to the second computer.
