1. A method of conferencing among a plurality of user sites, comprising the steps of:
- storing a common set of data objects in a plurality of digital computers, each of the digital computers located at a respective user site and having a memory for data object storage and a monitor for data object display, wherein the storing step occurs prior to a conference among the user sites;
interconnecting the plurality of user sites into the conference via a wide area network;
at an individual user site, selecting a data object from the common set of data objects and transmitting a control signal to the other user sites via the network to indicate the selected data object; and
at each of the other user sites, receiving the control signal and displaying the selected data object on the respective digital computer monitor in response to the control signal.

Abstract
A teleconferencing system for voice and data provides interconnections among user sites via a central station. User stations at user sites each alternate operation between a data mode connecting a user computer and modem to a user telephone communication path and a voice mode connecting a telephony circuit to the communication path. The teleconferencing system is adapted for conducting a voice conference over standard telephone lines while allowing simultaneous viewing of data objects such as slides, graphs, or text. A host computer connected to the central station serves as a central repository for storage and retrieval of data objects for use in teleconferences.
