Abstract

A method and apparatus for providing broadband conferencing services is provided. The method includes the steps of establishing a voice channel over a circuit switched telephone network and a virtual data channel over a packet data network between at least two parties. The apparatus includes a telephone line and a digital data line sharing a single subscriber loop in addition to a system for establishing a virtual data channel over a packet data network. Further, an advanced intelligent network telephone network having a first database of customer premise equipment and a second database having data addresses associated with the customer premise equipment is disclosed.
