Abstract

A computer-based conferencing system capable of selectively conferencing with a remote node over two or more different transports. A host processor controls the generation of local conferencing signals for transmission to the remote node over either a first transport or a second transport. The host processor also controls the processing of remote conferencing signals received from the remote node over either the first transport or the second transport. In a preferred embodiment, the first transport is an ISDN network and the second transport is a LAN network. In one embodiment, the computer system has a combined audio/ISDN board, a video board, and a LAN card. In an alternative embodiment, the computer system has a combined audio/video board, an ISDN board, and a LAN card.
