Abstract

Disclosed is a system and method for on-demand recording of telephone, computer, or video signals. Once a connection is established, the communication signals are sent through an intermediary device, which duplicates the signals. The signals are then stored in memory until a triggering event occurs during the connection. If the triggering event occurs, then the signals in memory are stored for playback. If the triggering event does not occur prior to the termination of the connection, the signals in memory are erased.

Claims

1. A method for on-demand recording of voice information, the method comprising:

establishing a call between communication devices within a private branch exchange (PBX) via at least one line card of a plurality of line cards;

dynamically duplicating information of the call at the at least one of the plurality of line cards;

digitizing and packetizing the duplicated information for transmission on a network, external to the PBX;

transmitting the digitized and packetized information to a server adapted to couple to the PBX;

dynamically storing the transmitted information by a server coupled to the network;

receiving a triggering event at any time after the dynamically storing call, wherein the triggering event occurs after initiation of dynamically storing; and

upon receipt of the triggering event and conclusion of the call, saving the digitized and packetized information corresponding to an entirety of the call on the server so that the saved digitized and packetized information can be replayed on-demand.

2. The method of claim 1 wherein the triggering event is initiated from a telephone.

3. The method of claim 2 wherein the triggering event is initiated remotely from the telephone.

4. The method of claim 1 wherein the triggering event is initiated from a network device.

5. The method of claim 1 wherein the triggering event is initiated from a server connected to the private branch exchange (PBX) device.
