Abstract

Methods and systems are described for monitoring communications in a packet-switched network. More specifically, the system initiates a communication between a network endpoint associated with a call mediator and at least a second network endpoint; records, at the call mediator, information associated with the communication; and upon termination of the communication, communicates, from the call mediator to an enterprise gatekeeper, the information associated with the communication.

Claims (55)

1. A computerized method for monitoring communications in a packet switched network, the method comprising:

initiating a communication between a network endpoint associated with a call mediator and at least a second network endpoint;

recording, at the call mediator, information associated with the communication, wherein recording information associated with the communication comprises recording an alphanumeric termination cause code generated by the call mediator indicating a reason the communication was disconnected;

upon termination of the communication, communicating, from the call mediator to an enterprise gatekeeper, the information associated with the communication;

translating the alphanumeric termination cause code into a numeric termination cause code, wherein translating the alphanumeric termination cause code is performed by the enterprise gatekeeper;

creating an authentication record containing information associated with the communication by parsing the information associated with the communication;

communicating the authentication record from the enterprise gatekeeper to a remote authentication server; and

creating a billing call record by parsing the authentication record.

2. The method of claim 1 wherein the communication comprises a VoIP communication.

3. The method of claim 1 wherein recording information associated with the communication comprises recording a network identifier associated with a network endpoint, wherein the network identifier specifies an enterprise customer network in which the network endpoint resides.

4. The method of claim 1 wherein recording information associated with the communication comprises recording the start time of the communication.

5. The method of claim 1 , wherein recording information associated with the communication comprises recording the stop time of the communication.

6. The method of claim 1 , wherein recording information associated with the communication comprises recording the duration of the communication.

7. The method of claim 1 , wherein recording information associated with the communication comprises recording an amount of data transferred between the network endpoints.

8. The method of claim 1 , comprising a call mediator located at a customer site serviced by an enterprise gatekeeper located at a different location.

9. The method of claim 8 , comprising a call mediator controlled by a customer and an enterprise gatekeeper controlled by a service provider.

10. The method of claim 9 , wherein recording information associated with the communication comprises recording information that is accessible to the customer controlling the call mediator.

11. The method of claim 10 , comprising storing, at the enterprise gatekeeper, information associated with the communication.

12. The method of claim 11 , wherein the information associated with the communication stored at the enterprise gatekeeper is not accessible to the customer.

13. The method of claim 1 , wherein communicating, from the call mediator to the enterprise gatekeeper, the information associated with the communication comprises communicating the information in a disconnect request.

14. The method of claim 13 , wherein communicating the information in a disconnect request comprises communicating a disconnect request containing a billing token containing information associated with the communication.

15. The method of claim 1 , wherein translating the alphanumeric termination cause code comprises translating to a PSTN numeric termination cause code.

16. A computerized method for monitoring communications in a packet switched network, the method comprising:

initiating a communication between a network endpoint associated with a call mediator and at least a second network endpoint;

recording, at the call mediator, information associated with the communication, including an alphanumeric termination cause code generated by the call mediator indicating a reason the communication was disconnected;

upon termination of the communication, communicating, from the call mediator to an enterprise gatekeeper, the information associated with the communication;

translating the alphanumeric termination cause code into a PSTN numeric termination cause code;

creating an authentication record containing information associated with the communication by parsing the information associated with the communication;

communicating the authentication record from the enterprise gatekeeper to a remote authentication server; and

creating a billing call record by parsing the authentication record.

17. The computerized method of claim 16 , wherein the information associated with the communication comprises a network identifier associated with a network endpoint, the network identifier specifying an enterprise customer network in which the network endpoint resides.

18. A system for monitoring communications in a packet switched network, the system comprising:

a first network endpoint associated with a call mediator;

at least a second network endpoint; and

an enterprise gatekeeper;

wherein the first network endpoint initiates a communication with the second network endpoint;

wherein the call mediator records information associated with the communication, wherein the information associated with the communication comprises an alphanumeric termination cause code generated by the call mediator indicating a reason the communication was disconnected;

wherein upon termination of the communication, the call mediator communicates to the enterprise gatekeeper, the information associated with the communication;

wherein the enterprise gatekeeper is programmed to translate the alphanumeric termination cause code to a PSTN numeric termination cause code;

wherein the enterprise gatekeeper is programmed to create an authentication record containing information associated with the communication by parsing the information associated with the communication;

wherein the enterprise gatekeeper is programmed to communicate the authentication record to a remote authentication server; and

wherein the remote authentication server is programmed to create a billing call record by parsing the authentication record.

19. The system of claim 18 , wherein the call mediator is located at a customer site serviced by an enterprise gatekeeper located at a different location.

20. The system of claim 19 , wherein the call mediator is controlled by a customer and the enterprise gatekeeper is controlled by a service provided.

21. The system of claim 20 , wherein the information associated with the communication recorded at the call mediator is accessible to the customer controlling the call mediator.

22. The system of claim 21 , wherein the enterprise gatekeeper stores the information associated with the communication received from the call mediator.

23. The system of claim 22 , wherein the information associated with the communication stored at the enterprise gatekeeper is not accessible to the customer.

24. The system of claim 18 , wherein the information associated with the communication is communicated in a disconnect request.

25. The system of claim 24 , wherein the disconnect request contains a billing token containing information associated with the communication.

26. The system of claim 18 , wherein the information associated with the communication comprises an amount of data transferred between the network endpoints.

27. The system of claim 18 , wherein the information associated with the communication comprises the duration of the communication.

28. The system of claim 18 , wherein the communication comprises a VoIP communication.

29. The system of claim 18 , wherein the information associated with the communication comprises a network identifier associated with a network endpoint, wherein the network identifier specifies an enterprise customer network in which the network endpoint resides.

30. The system of claim 18 , wherein the information associated with the communication comprises the start time of the communication.

31. The system of claim 18 , wherein the information associated with the communication comprises the stop time of the communication.
