Dataconferencing method
First Claim
1. A method of dataconferencing between two or more sites at which a shared voice call network and a shared data network are both accessible, each of the sites including a display device, comprising:
- at each of the sites, providing a telephone receiver and a dataconference control unit coupled to the voice call network, and providing a network interface coupled to the data network, the dataconference control unit at each site being coupled to the display device and the network interface at said site;
providing an image source for producing image data representative of an image, the image source coupled to one of the network interfaces;
establishing a voice call session between the telephone receivers of the sites over the voice call network for transmission of voice communications therebetween;
at the dataconference control unit of a first one of the sites, obtaining a network device access code and transmitting the network device access code within the voice call session;
at the dataconference control unit of at least a second one of the sites, receiving the network device access code transmitted from the first site;
in response to receiving the network device access code at the second site, establishing a data communication session between the sites via the data network using the network device access code;
transmitting the image data between the sites via the data network; and
displaying the image at the sites via the display devices.

Abstract
Geographically distributed conference sites each have a telephone receiver and a dataconferencing appliance connected to a shared voice call network. Each site also has a display device for displaying images comprised of image data produced by an image source. The dataconferencing appliance is connected to a data network that links the sites independently of the voice call network. To initiate a dataconference session between the sites, a voice call session is first established between the telephone receivers via the voice call network. An access negotiation procedure implemented in software or hardware of the dataconferencing appliance is then manually initiated to identify a network device access code and communicate it to at least a second one of the sites within the voice call session. The network device access code is used to establish a data communication session via the data network for convenient transmission of image data between the sites.
