Abstract

A method of operating a communication signaling processor is disclosed. The method comprises receiving a signaling message for a voice call to a called party, processing the signaling message to transfer a query to a database that is updated when the called party changes locations, receiving a response from the database, and processing the response to select an identifier for a header of a voice communication to route the voice call to the called party.

Claims

1. A method of operating a communication signaling processor, the method comprising:

receiving a signaling message for a voice call to a called party;

processing the signaling message with a virtual private network plan to transfer a query to a database that is updated when the called party changes locations;

receiving a response from the database;

processing the response to select an identifier for packet headers of a packetized voice communication to route the voice call to the called party; and

transferring an Internet Protocol message indicating the selected identifier.

2. The method of claim 1 wherein the signaling message comprises a signaling system seven message.

3. The method of claim 1 wherein the signaling message comprises an initial address message.

4. The method of claim 1 wherein the identifier comprises an asynchronous transfer mode virtual path identifier.

5. The method of claim 1 wherein the identifier comprises an asynchronous transfer mode virtual channel identifier.

6. The method of claim 1 wherein the header comprises asynchronous transfer mode cell header.

7. The method of claim 1 wherein processing the signaling message with the virtual private network plan comprises processing the signaling message with the virtual private network plan in response to a caller number for the voice call.

8. The method of claim 1 wherein processing the signaling message with the virtual private network plan comprises processing the signaling message with the virtual private network plan in response to a called number for the voice call.

9. The method of claim 1 wherein processing the signaling message with the virtual private network plan comprises processing the signaling message with the virtual private network plan in response to an incoming line for the voice call.

10. The method of claim 1 further comprising:

receiving another signaling message indicating that the called party is busy; and

processing the other signaling message to select another identifier for the packet headers of the packetized voice communication for the voice call to route the voice call to a voice messaging platform.

11. The method of claim 10 wherein the other identifier comprises an asynchronous transfer mode virtual path identifier.

12. The method of claim 10 wherein the other identifier comprises an asynchronous transfer mode virtual channel identifier.

13. The method of claim 10 wherein the header comprises asynchronous transfer mode cell header.

14. A method of operating a communication signaling processor, the method comprising:

receiving a signaling message for a voice call to a called party;

processing the signaling message to transfer a query to a database that is updated when the called party changes locations;

receiving a response from the database;

processing the response to select an identifier for packet headers of a packetized voice communication to route the voice call to the called party;

transferring an Internet Protocol message indicating the selected identifier;

receiving another signaling message indicating that the called party is busy; and

processing the other signaling message to select another identifier for the packet headers of the packetized voice communication to route the voice call to a voice messaging platform.

15. The method of claim 14 wherein the other signaling message comprises a signaling system seven message.

16. The method of claim 14 wherein the other signaling message comprises a release message.

17. The method of claim 14 wherein the other identifier comprises an asynchronous transfer mode virtual path identifier.

18. The method of claim 14 wherein the other identifier comprises an asynchronous transfer mode virtual channel identifier.

19. The method of claim 14 wherein the header comprises asynchronous transfer mode cell header.
