Abstract
A method of obtaining information associated with a Voice over Internet Protocol (VoIP) communication session includes tapping the computer network passively to obtain signaling information and media information in a first format, separating the signaling information from the media information, transcoding the media information to a second format, and storing the transcoded media information in the second format. The media information includes data, voice, audio, and/or video information. A system adapted to obtain information associated with a VoIP communication session on a computer network includes a tapping device to passively tap the computer network to obtain signaling information and media information in a first format, a processing device adapted to transcode the media information from the first format to a second format and separate the signaling information from the media information, and a storage device adapted to store the transcoded media information in the second format.
