Abstract

A clearinghouse server for routing multi-media communications, including telephony calls, between a source device and a destination device via a distributed computer network, such as the global Internet. The clearinghouse server can authorize the completion of a communication from a source device to a destination device and collect usage-related information for the completed communication. In response to an authorization request issued by an enrolled source device, the clearinghouse server can identify one or more available destination devices available to accept a communication from an authorized source device. The clearinghouse server can provide a list of the identified destination devices, typically organized in a rank order, by sending an authorization response to the source device. In turn, the source device can use this list to select a destination device and contact that selected device via the computer network to complete the communication.

Claims

1. A method for authorizing and routing a communication with a clearinghouse server between a source device and a destination device, comprising the steps of:

receiving an authorization request from a source device;

determining a communication route for completing a communication originating at the source device;

identifying one or more destination devices available to complete the communication;

balancing use of the one or more destination devices with the clearinghouse server by ranking the one or more destination devices with weighted values which are assigned to each destination device;

generating a list comprising the ranked destination devices;

forwarding the list to the source device; and

receiving a selection of a destination device from the list.

2. The method of claim 1, wherein each device comprises a Voice over Internet Protocol device.

3. The method of claim 1, wherein ranking the one or more destination devices comprises applying an algorithm that determines the weighted values.

4. The method of claim 1, further comprising:

generating an authorization token and a transaction identifier for each identified destination device.

5. The method of claim 1, further comprising:

creating a call detail record.

6. The method of claim 5, wherein the step of creating the call detail record further comprises the step of storing one of a transaction identifier, the identified destination devices, tokens corresponding to each identified destination device, a source group number assigned to the source device, a destination group number corresponding to each destination device, calling party identity, called maximum authorized call length, a time date stamp, and a server identification number.

7. The method of claim 1, further comprising the step of extracting communication information from the authorization request.

8. The method of claim 7, wherein the step of extracting communication information further comprises the steps of extracting one of a source device identity, dialed number, and call identifier from the authorization request.

9. The method of claim 1, further comprising the step of determining if the source device is enrolled with the clearinghouse server.

10. The method claim 1, further comprising ordering destination devices based on a destination group assignment for each of the destination devices.

11. The method of claim 10, wherein a number of devices in a destination group identified as destination VoIP devices are truncated.

12. The method of claim 11, wherein destination devices suggested by the source device can be combined with destination devices identified by the clearinghouse server.

13. The method of claim 11, wherein destination devices suggested by the source device are ranked ahead of devices identified by the clearinghouse server.

14. The method of claim 1, wherein source devices are assigned to source groups and destination devices are assigned to device groups for the purpose of determining authorization and routing of traffic between source and destination devices.

15. A system for authorizing and routing a communication with a clearinghouse server between a source device and a destination device, comprising:

means for receiving an authorization request from a source device;

means for determining a communication route for completing a communication originating at the source device;

means for identifying one or more destination devices available to complete the communication;

means for balancing use of the one or more destination devices by ranking the one or more destination devices with weighted values which are assigned to each destination device;

means for generating a list comprising the ranked destination devices;

means for forwarding the list to the source device; and

means for receiving a selection of a destination device from the list.

16. The system of claim 15, wherein each device comprises a Voice over Internet Protocol device.

17. The system of claim 15, wherein the means for balancing comprises means for ranking the one or more destination devices using an algorithm that determines the weighted values.

18. The system of claim 15, further comprising means for generating an authorization token and a transaction identifier for each identified destination device.

19. The system of claim 15, further comprising means for creating a call detail record.

20. The system of claim 19, wherein the means for creating the call detail record further comprises means for storing one of a transaction identifier, the identified destination devices, tokens corresponding to each identified destination device, a source group number assigned to the source device, a destination group number corresponding to each destination device, calling party identity, called maximum authorized call length, a time date stamp, and a server identification number.
