Method and apparatus for Voice-over-IP call recording
First Claim
1. A method of obtaining information associated with a VoIP communication session on a computer network comprising:
- tapping the computer network passively to obtain signaling information and media information, 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.

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.
