4. The communications network arrangement of claim 3 , wherein said signalling network comprises a Common Channel Signaling 7 network.

5. The communications network arrangement of claim 2 wherein said computer comprises a non-transitory machine readable storage medium storing software of said gateway address translator.

6. The communications network arrangement of claim 1 , wherein at least one of said first and second media gateway controllers is implemented in a distributed architecture in which a first processor performs ingress processing and a second processor performs egress processing.

7. The communications network arrangement of claim 1 , wherein at least one of said first and second media gateway controllers is implemented as a soft switch.

8. The communications network arrangement of claim 1 , wherein one of the first and second media gateway controllers is included in said computer.

9. The communications network arrangement of claim 1 , wherein the first media gateway controller is provisioned with an address of a first one of the proxies instead of an address of the first media gateway, and wherein the second media gateway controller is provisioned with an address of a second one of the proxies instead of an address of the second media gateway.

10. The communications network arrangement of claim 1 , wherein in response to receiving the control message from said first media gateway controller, a first of said proxies is configured to:

substitute, in the control message, an address of said first media gateway controller with an address of the first proxy, and

forward the control message containing the address of the first proxy to the first media gateway.

11. A system comprising:

a first media gateway controller configured to control a first media gateway, wherein the first media gateway controller is provided with a first operating protocol;

a second media gateway controller configured to control a second media gateway, wherein the second media gateway controller is provided with a second, different operating protocol;

a computer configured to:

perform address translation and provide proxies for said first media gateway and said second media gateway, wherein the address translation substitutes, in a message, an address of one of the proxies in place of an address of a corresponding one of the first and second media gateway controllers;

provide virtual gateways for respective ones of said first and second media gateway controllers, wherein said virtual gateways perform virtual bearer messaging between said first media gateway controller and said second media gateway controller;

relay messages between said first media gateway controller and said first media gateway; and

relay messages between said second media gateway controller and said second media gateway.

12. The system of claim 11 , wherein a first one of the proxies is configured to communicate with the first media controller using the first operating protocol, and a second one of the proxies is configured to communicate with the second media gateway controller using the second operating protocol, wherein an address of the first proxy rather than an address of the first media gateway is provisioned at the first media gateway controller, and an address of the second proxy rather than an address of the second media is provisioned at the second media gateway controller.

13. A method comprising:

receiving, by a computer, a first control message from a first media gateway controller configured to control a first media gateway, wherein the first control message is according to a first operating protocol;

in response to the first control message, a first proxy in the computer forwarding the first control message to the first media gateway;

receiving, by the computer, a second control message from a second media gateway controller configured to control a second media gateway, wherein the second control message is according to a second operating protocol;

in response to the second control message, a second proxy in the computer forwarding the second control message to the second media gateway; and

relaying, by the computer, a third message between the first and second media gateway controllers to provide virtual bearer messaging between the first and second media gateway controllers.

14. The method of claim 13 , wherein the first media gateway controller is provisioned with an address of the first proxy instead of an address of the first media gateway, and wherein the second media gateway controller is provisioned with an address of the second proxy instead of an address of the second media gateway.

15. The method of claim 13 , further comprising:

the first proxy substituting, in the first control message, an address of the first media gateway controller with an address of the first proxy;

wherein the first proxy forwarding the first control message comprises sending the first control message containing the address of the first proxy to the first media gateway;

the second proxy substituting, in the second control message, an address of the second media gateway controller with an address of the second proxy; and

wherein the second proxy forwarding the second control message comprises sending the second control message containing the address of the second proxy to the second gateway.

16. A communication network arrangement comprising:

a plurality of media gateways;

a plurality of media gateway controllers, wherein each media gateway controller is configured to control a corresponding one of the media gateways, wherein said media gateway controllers are to employ different operating protocols to communicate with the corresponding media gateways, wherein each of said media gateway controllers and the corresponding one of the media gateways form a respective pair that communicate using a corresponding one of the operating protocols; and

a computer configured to perform gateway address translation between each paired media gateway and media gateway controller, wherein said computer is configured to further perform virtual bearer messaging between said plurality of media gateway controllers.

17. A non-transitory machine-readable storage medium storing instructions that when executed cause a computer to perform:

receiving a first control message from a first media gateway controller configured to control a first media gateway, wherein the first control message is according to a first operating protocol;
