Abstract

A system and method for recording and/or otherwise monitoring IP multimedia sessions. The present invention features a recording and/or monitoring device, referred to hereinafter as “a recording device” for the purposes of clarity only and without any intention of being limiting. The recording device is a participant in the IP multimedia session, although preferably the recording device only receives data for recording and/or otherwise monitoring the session. Therefore, the IP multimedia session is preferably a multi-user session, such as a “conference call” for example, even if data is being provided for recording from only one of the participants in the session.
