A multipoint communication system uses Internet protocol trunking to facilitate communication between media control units (for sending and receiving multipoint communication signals between end-point devices), a media gateway (for translating between non-Internet protocol multipoint communication signals and Internet protocol communication signals), and a controller (for establishing and controlling a multipoint communication session between the end-point devices). In addition, a multimedia gateway (for use in a multipoint communication system) is described that incorporates an interactive voice response unit through which users of non-Internet protocol devices (connected to the multimedia gateway) interact to establish a communication session with a multipoint communication system.
