Abstract

A system and method for distributing and managing the flow of information between a plurality of networks uses a device that can receive voice and data signals simultaneously through a single communication point from a remote integrated voice/data network and distribute these signals to one or more end terminals connected to a local network. The device has a specific telephone number and an IP address for receiving voice and data signals from the remote network. Upon receiving voice and/or data signals, the device determines which end terminal connected to the local network is to receive the incoming signal and routes the signal to the appropriate terminal. The device can also transmit voice and data signals from the local network to the remote network and serve as a firewall for both incoming and outgoing transmissions.

Claims

1. A system for managing the flow of information between a plurality of networks, comprising:

a wide area network providing voice signals and data signals;

a local area network capable of routing voice signals and data signals to a plurality of end terminals; and

communication management means, coupled between the wide area network and the local area network, for simultaneously receiving voice signals and data signals from the wide area network through a single communication point, analyzing the received voice signals and data signals for determining a signal type, and for distributing the voice signals and data signals to the appropriate end terminals based upon the signal type.

2. The system of claim 1 wherein the communication management means includes a processor.

3. The system of claim 1 wherein the communication management means includes a memory.

4. The system of claim 1 wherein the communication management means has a telephone number address and an Internet protocol address.

5. The system of claim 1 wherein the communication management means includes a firewall.

6. The system of claim 1 wherein the communication management means includes a communications port.

7. The system of claim 1 wherein the communication management means includes a disc storage device.

8. A communication management device for managing the flow information between a plurality of networks, comprising:

a memory;

a processor in communication with the memory; and

communication management means for receiving voice signals and data signals simultaneously from a remote network through a single communication point, analyzing the received voice signals and data signals for determining a signal type, and distributing the voice signals and data signals to at least one of a plurality of end terminals connected to a local network based on the signal type.

9. The communication management device of claim 8 wherein the memory is a random access memory.

10. The communication management device of claim 8 wherein the remote network is a wide area network.

11. The communication management device of claim 8 wherein the local network is a local area network.

12. The communication management device of claim 8 wherein the communication management means includes a telephone number and an Internet protocol address.

13. A method for managing the flow of information between a plurality of networks, comprising:

receiving voice signals and data signals simultaneously at a communication management device through a single communication point from a first network;

analyzing the received voice signals and data signals for determining a signal type; and

distributing the voice signals and data signals to one of a plurality of end terminals connected to a second network through the communication management device based on the signal type.

14. The method of claim 13 further comprising routing voice information to a telephone number address associated with the communication management device.

15. The method of claim 13 further comprising routing voice information to an Internet protocol address associated with the communication management device.

16. The method of claim 13 wherein determining includes:

determining the format of the voice and data information; and

identifying at least one of the plurality of end terminals capable of outputting the voice and data information in the determined format.

17. The method of claim 16 wherein determining includes determining whether the format of the voice and data information is one of voice, voicemail, electronic mail, video, telephone, and facsimile.

18. The method of claim 13 further comprising:

sending voice and data information from at least one of the plurality of end terminals to the communication management device; and

transmitting the voice and data information through a firewall to the first network.

19. The method of claim 18 wherein transmitting includes determining the format of the voice and data information before transmitting to the first network.
