Abstract: Restoring at least a portion of a telephone communication session, in which at least the following occur. Data packets transmitted over a computer network are received. Audio or video data contained in the data packets is stored. The portion of the telephone communication session from the audio or video data contained in the data packets is restored. A terminal having a user interface, a data entry device and a display unit suitable for outputting audio data, video data, or both audio and video is provided. The portion of the telephone communication session is output using the display unit.

Abstract: Storing at least a portion of a computer network-based session such as a telephone session being performed on a computer network between a packet source and a packet destination, in which the following can occur in an embodiment of the invention. Data packets are received on the computer network. Each data packet is filtered to determine if said data packet is a session packet. If the data packet is a session packet, it is filtered to determine if the data includes session data. If the data includes session data, the session data is analyzed. The session packet is stored such that the stored session packet comprises a portion of the telephone session.

Abstract: Monitoring of data packets transmitted across a computer network to extract a computer network-based telephone session in response to a request in which at least the following occur. Data packets transmitted on the computer network are analyzed to select one or more data packets that contain audio data, video data, or audio and video data (“data”). Packets associated with one or more IP addresses representing sessions to be monitored are identified. The data contained in the identified data packets are stored. The data contained in the identified data packets are organized into a specific telephone session based at least in part on a computer network-based telephone session to which the data packets belong. The data that is included in the organized data packets is output upon receipt of a signal representing the request of a user for the specific telephone session.

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.
