Abstract

A system and a method for monitoring a computer network to detect data packets including audio or video data, such packets being part of a communication session, for storing these packets and for reconstructing the communication session upon request. To enable the system to store packets independently of the protocol used to set up the communication session, for example in a Voice Over IP environment, the system includes a link to the gatekeeper of the computer network.

Claims

1-28. -28. (canceled)

29. A management control unit connected to a computer network for use in a computer network-based communication sessions, consisting of:

(a) a first, bi-directional communication link to a user computer having a user interface, a keyboard, and a display, the first link conveying a request from a user to the management control unit and displaying at least a portion of the computer network-based communication session;

(b) a second communication link to the computer network-based communication sessions;

(c) a third, bi-directional communication link to a storage unit;

(d) a fourth link between a gatekeeper and the management unit that transmits CTI or CDR data;

(e) a database that stores call details transmitted on said fourth link;

(f) a fifth, bi-directional communication link to a data restore module, the data restore module having at least a video codec or an audio codec and being configured to restore at least the portion of the computer network-based communication session; and

(g) means for retrieving from the storage unit one or more data packets and for transferring same across the fifth communication links to the data restore unit in response to the request by the user at the user computer.
