Quality correlation testing

1. A service provider network comprising:

a session border controller for controlling traffic between an access provider network and the service provider network;

a quality correlation system in the service provider network; and

a client device;

the session border controller configured to receive a first session quality message for a session transferred from an origination device in the access provider network to a gateway in the service provider network, receive a second session quality message for the session transferred from the gateway to the origination device, and transfer the first session quality message and the second session quality message to the quality correlation system;

the quality correlation system configured to receive the first session quality message and the second session quality message from the session border controller, receive signaling information for the session, process the signaling information with the first session quality message and the second session quality message to determine a session status message for the session, and transfer the session status message to the client device; and

the client device configured to receive and display the session status message.

2. The service provider network of claim 1 wherein the session border controller is configured to receive the first session quality message and the second session quality message at the end of the session.

3. The service provider network of claim 1 wherein the session border controller is configured to receive the first session quality message and the second session quality message periodically during the session.

4. The service provider network of claim 1 wherein the first session quality message and the second session quality message comprise real-time transport control protocol (RTCP) messages.

5. The service provider network of claim 1 wherein the signaling information comprises a session initiation protocol (SIP) message and an H.248 message.

6. The service provider network of claim 1 wherein the session status message indicates a failure of the session and a path of the failure.

7. The service provider network of claim 6 wherein the path of the failure indicates a network element in the service provider network.

8. The service provider network of claim 6 wherein the path of the failure indicates the access provider network.

9. The service provider network of claim 1 wherein the session border controller is further configured to transfer the first session quality message and the second session quality message to the quality correlation system in response to a query from the quality correlation system.

10. The service provider network of claim 1 wherein the session comprises a voice over packet session.

11. A method of operating a service provider network comprising a session border controller for controlling traffic between an access provider network and the service provider network, a quality correlation system in the service provider network, and a client device, the method comprising:

in the session border controller, receiving a first session quality message for a session transferred from an origination device in the access provider network to a gateway in the service provider network, receiving a second session quality message for the session transferred from the gateway to the origination device, and transferring the first session quality message and the second session quality message to the quality correlation system;

in the quality correlation system, receiving the first session quality message and the second session quality message from the session border controller, receiving signaling information for the session, processing the signaling information with the first session quality message and the second session quality message to determine a session status message for the session, and transferring the session status message to the client device; and

in the client device, receiving and displaying the session status message.

12. The method of claim 11 wherein further comprising the session border controller receiving the first session quality message and the second session quality message at the end of the session.

13. The method of claim 11 further comprising the session border controller receiving the first session quality message and the second session quality message periodically during the session.

14. The method of claim 11 wherein the first session quality message and the second session quality message comprise real-time transport control protocol (RTCP) messages.

15. The method of claim 11 wherein the signaling information comprises a session initiation protocol (SIP) message and an H.248 message.

16. The method of claim 11 wherein the session status message indicates a failure of the session and a path of the failure.

17. The method of claim 16 wherein the path of the failure indicates a network element in the service provider network.

18. The method of claim 16 wherein the path of the failure indicates the access provider network.

19. The method of claim 11 further comprising the session border controller transferring the first session quality message and the second session quality message to the quality correlation system in response to a query from the quality correlation system.

20. The method of claim 11 wherein the session comprises a voice over packet session.
