Abstract

A system for routing voice telephone calls over IP networks as opposed to traditional switched circuit networks. The voice communications during the telephone call are packaged as digital data and access the Internet through gateways. The system supports the linking of a source gateway in a first clearinghouse to a destination gateway in a second clearinghouse. The system further supports the selection of a destination gateway based on factors such as cost, speed of routing, and transmission quality of the voice data. The components of the system are arranged so as to minimize the number of signals sent between clearinghouses in identifying the optimal destination gateway.

Claims

1. A method for routing internet protocol transactions between gateways of different clearinghouses, comprising the steps of:

tracking internet protocol transactions of first gateways with a first clearinghouse;

tracking internet protocol transactions of second gateways with a second clearinghouse;

receiving gateway information associated with the first clearinghouse;

receiving gateway information associated with the second clearinghouse;

storing the received gateway information in a database of a linking clearinghouse prior to a call;

receiving a destination gateway request from a source gateway of the first clearinghouse;

generating a list of available destination gateways of the second clearinghouse based upon the received gateway information and by creating a combined routing table, the combined routing table comprises gateway information from the first clearinghouse and the one or more second clearinghouses; and

selecting a destination gateway from the list based on one or more business rules.

2. The method of claim 1, further comprising completing the internet protocol transaction between the source gateway of the first clearinghouse and the selected destination gateway of the second clearinghouse, the internet protocol transaction comprising an internet telephony call.

3. The method of claim 1, wherein the step of selecting a destination gateway further comprises the step of sorting destination gateways based upon the one or more business rules.

4. The method of claim 3, wherein the business rules further consider at least one of speed and quality of data transmission for completing a internet protocol transaction.

5. The method of claim 1, wherein the business rules further consider at least one of speed and quality of data transmission for completing a internet protocol transaction.

6. The method of claim 1, wherein the linking clearinghouse performs the step of selecting a destination gateway from the list.

7. The method of claim 6, wherein the business rules further consider at least one of speed and quality of data transmission for completing a internet protocol transaction.

8. A system for routing internet protocol transactions between gateways, comprising:

a first clearinghouse comprising one or more first gateways connected to a first computer network;

a second clearinghouse comprising one or more second gateways connected to a second computer network; and

a linking clearinghouse connected to the first and second clearinghouse, for receiving gateway information from said first and said second clearinghouses prior to an internet protocol transaction associated with first gateways of the first clearinghouse and associated with second gateways of the second clearinghouse, for tracking internet protocol transactions of the first gateways being tracked by the first clearinghouse and for tracking internet protocol transactions of the second gateways being tracked by the second clearinghouse, the linking clearinghouse generating a list of available destination gateways based upon the gateway information in response to internet protocol transactions associated with the first and second gateways and by creating a combined routing table, the combined routing table comprises gateway information from the first clearinghouse and one or more second clearinghouses, and the linking clearinghouse selecting a destination gateway from the list based on one or more business rules.

9. The system of claim 8, wherein the first computer network and second computer network each comprise an IP network, the internet protocol transactions comprising one or more internet telephony calls.

10. The system of claim 8, wherein the internet protocol transactions of the first gateways being tracked by the first clearinghouse and the internet protocol transactions of the second gateways being tracked by the second clearinghouse comprise internet telephony type calls.

11. The system of claim 8, wherein the linking clearinghouse receives a cost schedule from the first clearinghouse and from the second clearinghouse.

12. The system of claim 11, wherein the internet protocol transactions of the first gateways being tracked by the first clearinghouse and the internet protocol transactions of the second gateways being tracked by the second clearinghouse comprise internet telephony type calls.

13. The system of claim 8, wherein the one or more business rules further evaluate at least one of speed and quality of data transmission for completing a internet protocol transaction.

14. The system of claim 13, wherein the internet protocol transactions of the first gateways being tracked by the first clearinghouse and the internet protocol transactions of the second gateways being tracked by the second clearinghouse comprise internet telephony type calls.

15. The system of claim 8, wherein the gateway information received by said linking clearinghouse comprises destination gateway IP address information.

16. A method for routing internet protocol transactions between gateways, comprising the steps of:

receiving first criteria from a first clearinghouse with a linking clearinghouse;

receiving second criteria from a second clearinghouse with the linking clearinghouse;

enrolling the linking clearinghouse as a destination gateway in the first clearinghouse;

receiving a internet protocol transaction from the first clearinghouse with the linking clearinghouse;

generating a list of available destination gateways operating under control of the second clearinghouse; and

computing a cost for routing internet protocol transactions between gateways, wherein computing the cost comprises;

applying a price discount to the cost of originating a internet protocol transaction with a gateway from the first clearinghouse; and

applying a price increase to the cost of terminating the internet protocol transaction with a gateway from the second clearinghouse.

17. The method of claim 16, wherein the first criteria and second criteria comprise summary interconnect criteria, the internet protocol transaction comprising an internet telephony call.

18. The method of claim 17, wherein the interconnect criteria comprises one or more rate plans.

19. The method of claim 18, wherein the internet protocol transactions of the first gateways being tracked by the first clearinghouse and the internet protocol transactions of the second gateways being tracked by the second clearinghouse comprise internet telephony type calls.

20. The method of claim 16, wherein the internet protocol transactions of the first gateways being tracked by the first clearinghouse and the internet protocol transactions of the second gateways being tracked by the second clearinghouse comprise internet telephony type calls.
