Abstract

A system and method for recording and/or otherwise monitoring IP multimedia sessions. The present invention features a recording and/or monitoring device, referred to hereinafter as “a recording device” for the purposes of clarity only and without any intention of being limiting. The recording device is a participant in the IP multimedia session, although preferably the recording device only receives data for recording and/or otherwise monitoring the session. Therefore, the IP multimedia session is preferably a multi-user session, such as a “conference call” for example, even if data is being provided for recording from only one of the participants in the session.

Claims

1. A method for recording at least a portion of a plurality of IP data sessions each being between at least a first communication device and a second communication device through a network by a remotely located recording device, comprising for each IP data session:

initiating the data session by said first communication device and establishing a connection with said second communication device;

implementing the data session as a conference call through a conference controller in response to initiating the data session such that said first and second communication devices are respectively first and second participants;

using the conference controller, entering the remotely located recording device to said conference call as an additional participant, wherein the remotely located recording device receives as the additional participant at least the portion of the data session from each of the first and second participants; and

recording the data session received as the additional participant of said conference call using said recording device.

2. The method of claim 1, wherein the data session is an IP telephony session.

3. The method of claim 2, wherein initiating the data session is detected by a recording agent, and said recording agent contacts the recording device.

4. The method of claim 2, wherein the recording device joins the data session through a hunt group.

5. The method of claim 4, including the additional step of the gatekeeper identifying the hunt group.

6. The method of claim 5, including the additional step of the gatekeeper searching for a free line within the identified hunt group.

7. The method of claim 1, wherein the data session is an IP multimedia session.

8. The method of claim 7, wherein initiating the data session is detected by a recording agent, and said recording agent contacts the recording device.

9. The method of claim 7, wherein said first communication device is a gateway for receiving communication through a PSTN.

10. The method of claim 1, wherein said conference controller is a MCU.

11. The method of claim 1, wherein the step of entering the recording device to said conference call is in response to a command that the data session is to be recorded.

12. The method of claim 11, including the additional step of providing the command from a scheduler.

13. The method of claim 12, including the additional step of locating the scheduler with the recording device.

14. The method of claim 12, including the additional step of analyzing information about the IP data session at the scheduler to determine whether the IP data session is to be recorded.

15. The method of claim 14, wherein the information includes the identity of at least one of the first and second communication devices.

16. The method of claim 1, including the additional step of permitting a user of at least one of the first and second communication devices to determine whether the session is to be recorded prior to entering the recording device as the additional participant.

17. The method of claim 1, wherein the connection with the second communication device is established by passing IP addresses to a gatekeeper for performing IP address resolution and connecting to a device associated with the resolved IP address.

18. The method of claim 1, wherein the conference controller implements said conference call in response to a request to initiate the conference call.

19. The method of claim 18, wherein the request is from at least one of the recording device, the first communication device, the second communication device, and an other component on the network.

20. A system for recording an IP communication session through a network, comprising:

(a) a first communication device for initiating the IP communication session;

(b) a second communication device connected as a communication participant in the IP communication session;

(c) a conference controller for implementing the IP communication session as a conference call; and

(d) a recording device remote from the first communication device and the second communication device and connected as an additional communication participant in said conference call by the conference controller to receive as the additional participant at least the portion of the IP communication session from each of the first and second communication devices, thereby to enable said recording device to record the IP communication session received as the additional participant of said conference call.

21. The system of claim 20, further comprising a second communication device for participating in the IP communication session through said conference call, wherein said first communication device is located on a separate network portion from said second communication device.

22. The system of claim 21, wherein said separate network portion is a different network segment.

23. The system of claim 21, wherein said separate network portion is a different network.

24. The system of claim 20, wherein said conference controller is a MCU.

25. The system of claim 20, further comprising:

(e) a gatekeeper for receiving said request from said first communication device to initiate the IP communication session and for sending a request to said conference controller to initiate said conference call.

26. The system of claim 25, further comprising:

(f) a recording agent for controlling said recording device.

27. The system of claim 25, wherein the gatekeeper passes the communication session to the recording device.

28. The system of claim 26, further comprising:

(g) a recording agent control module for initiating participation of said recording device in said conference call.

29. The system of claim 26, wherein said recording device and said recording agent are implemented in a single device.

30. The system of claim 26, further comprising a telephone device connected to said gatekeeper through a PSTN for participating in the IP communication session as one of the first and second communication devices.

31. The system of claim 30, further comprising a scheduler for determining whether the IP communication session is recorded, said scheduler controlling said recording device.

32. The system of claim 31, wherein said conference controller is a MCU.

33. The system of claim 31, wherein the scheduler analyzes information about the IP multimedia session to determine whether the IP communication session is to be recorded.

34. The system of claim 33, wherein the information includes the identity of at least one of the first and second communication devices.

35. The system of claim 20, wherein the recording device is present on the IP network with the conference controller.

36. The system of claim 20, wherein the conference controller enables the recording device to participate in the conference call, and wherein the recording device receives communication exclusively through the conference controller.
