| 1. A method of passively recording information associated with a VoIP communication session on a computer network comprising:
tapping, by a tapping device, the computer network passively to obtain signaling information and media information without
establishing a voice session with a recording device, the media information being 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, thereby monitoring information associated with a VoIP communication
session on a computer network without requiring modification to the computer network and without impairing operation of the
computer network, the first and second formats being digital formats.
