Abstract

A system and method for recording and/or monitoring data by forwarding it, with or without analyzing or otherwise filtering the data itself. According to preferred embodiments of the present invention, the system and method are operative over IP networks. According to a preferred embodiment of the present invention, there is provided a system and method for forwarding data according to at least one characteristic of the data, such as the session'"'"'s metadata for example, without analyzing or otherwise filtering the data itself. According to another preferred embodiment of the present invention, before the data is forwarded to the recording device, pre-processing algorithms are performed according to a system preset or according to one or more rules.

Claims

1. A method for recording Internet Protocol (IP) media sessions through a network, comprising:

providing a recording system located externally to a communication system;

delivering to the recording system via telephony call integration (CTI) at least one characteristic of an IP media session;

assessing said at least one characteristic for compliance with at least one rule; and

if said at least one characteristic matches said at least one rule, sending a request from the recording system to a management unit of the communication system to forward data related to the IP media session to the recording system; and

forwarding data of the IP media session to the recording system after adjusting destination IP address and port.

2. The method of claim 1, wherein said at least one rule comprises a dynamic rule.

3. The method of claim 1, wherein said at least one rule comprises a static rule.

4. The method of claim 1, wherein said at least one rule comprises a deterministic rule.

5. The method of claim 1, wherein said at least one rule comprises a statistical rule.

6. The method of claim 5, wherein said statistical rule includes instructions to record a certain percentage of said session in a certain time interval.

7. The method of claim 1, wherein said at least one rule comprises an event driven rule.

8. The method of claim 1, wherein said at least one characteristic of the data comprises metadata.

9. The method of claim 1, comprising:

pre-processing the data of the IP media session before forwarding.

10. The method of claim 9, wherein said pre-processing comprises at least one of encapsulation, re-encapsulation, summation, compression, encryption or decryption of at least a portion of the data.

11. The method of claim 1 comprising compressing the data prior to forwarding.

12. The method of claim 1 comprising:

detecting initiation of the IP media session by a recording agent; and

contacting the recording device by the recording agent.

13. The method of claim 1, wherein said method further comprising at least one of the following steps:

displaying said forwarded data; and

recording said forwarded data.

14. The method of claim 1, wherein said at least one rule states that all data of the session is to be forwarded.

15. The method of claim 1, wherein said IP media session is one of the following sessions:

voice over IP sessions, video conference sessions, chat sessions, a trunk radio sessions and web collaboration sessions.

16. The method of claim 1, wherein said step of forwarding comprises duplicating only a portion of the data.

17. The method of claim 1, wherein said at least one rule is driven by an event which occurs externally to the session.

18. The method of claim 1, wherein the forwarding is performed by one of the parties participating in the IP media session.

19. The method of claim 18, wherein one of the participating parties is an IP telephone.

20. The method of claim 18, wherein one of the participating parties is a gateway.
