Abstract

A system and method for automatically data streaming a multiparty conference. The system allows a session moderator or other guests to request data streaming of the multiparty. The data-stream-initiation request is received from an Internet-based interface. Upon receiving the request, the conferencing system automatically establishes data streams of audio and visual data of the conference and transmits the data stream to call participants. The conferencing system is also configured to record the conference call and transcode the call for subsequent playback.
