Multipoint multimedia/audio conference using IP trunking
View Patent ↗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.

13. The system of claim 12 , wherein said at least one non-Internet protocol endpoint access the system through a single-dial conference service number (SDCSN).
14. The system of claim 1 , wherein at least one of said plurality of end-points access the system through a single-dial conference service number (SDCSN).
15. The system of claim 1 , wherein the media gateway is geographically separated from at least one of the plurality of media control units.
16. The system of claim 1 , wherein the media gateway is geographically separated from the controller.
17. The system of claim 1 , wherein the system comprises a Decomposed architecture.
18. The system of claim 1 , wherein the system comprises a virtual multipoint control unit architecture.
19. A multipoint communication system, comprising:
at least two media control units adapted to send and receive multipoint communication signals between a plurality of end-point devices;
at least one non-Internet protocol end-point device communicatively coupled to the at least two media control units; and
a controller adapted to establish and control a multipoint communication session between the plurality of end-point devices and the at least one non-Internet protocol end-point device through the at least two media control units,
wherein communication between the at least two media control units and the controller uses the Internet protocol, and
wherein the controller is formed by duplicate modules, one duplicate module in at least two of the plurality of media control units, the duplicate modules communicatively coupled together.
20. The system of claim 19 , wherein at least one of the plurality of end-point devices comprise a non-Internet protocol end-point device.
