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.

Claims

1. A method for monitoring data packets transmitted across a computer network in order to extract a computer network-based telephone session that has been performed through the computer network for display in response to a request, comprising the steps of:

(a) analyzing data packets that are transmitted on the computer network to select one or more data packets that contain audio data, video data, or audio and video data;

(b) identifying data packets that are associated with one or more IP addresses representing sessions to be monitored;

(c) storing the audio data, video data, or audio and video data contained in the identified data packets;

(d) organizing the audio data, video data, or audio and video data contained in the identified data packets into a specific telephone session based at least in part on a computer network-based telephone session to which the data packets belong; and

(e) outputting the audio data, the video data, or the audio and video data that is included in the organized data packets upon receipt of a signal representing the request of a user for the specific telephone session.

2. The method of claim 1, including the additional step of including in a database information extracted from the data packet including one or more selected from the group of:

one or more IP addresses, a time, a date, a channel, a dialed number, and a caller identification.

3. The method of claim 1, wherein the data is stored on a storage media that is accessible through the computer network.

4. The method of claim 1, wherein the computer network is a local area network (LAN) or a wide area network (WAN).

5. The method of claim 1, wherein the outputting step outputs the audio data, video data or audio and video data.

6. The method of claim 5, wherein the outputting step further comprises the step of displaying any video data included in the organized data packets on a computer monitor, a video monitor, or a display screen.

7. The method of claim 5, wherein the outputting step further comprises the step of producing any audio data included in the organized data packets as sound through an earphone or a loudspeaker.

8. The method of claim 1, wherein the identified data packets are among the selected data packets.
