ABSTRACT:
A process for converting a point-to-point multimedia call into a bridged multimedia call for accommodating multi-party conferencing. The process utilizes the bearer channel configuration of the standard BRI format to disconnect, one at a time, each bearer channel from the point-m-point call and to reconnect each line to a multipoint control unit, whereupon the reconnected lines are individually reformatted in accordance with standard video phone protocol. The process facilitates the continuous and uninterrupted exchange of audio information and data between the point-to-point participants throughout the disconnection and reconfiguration stages of the conversion.
