US Patent 8456507 Individual participant control of conference data

A conference call system with a plurality of endpoints, a participant control server, a conference bridge and a switch is described. A first endpoint transmits conference data to the participant control server. The participant control server transmits the conference data to the other endpoints. In response to requests from the endpoint, the participant control server transmits recorded conference data for video, audio and web sessions that are individually controllable to pause, fast-forward and rewind the conference data. The participant control server establishes secondary connections for the endpoints including a ghost hold and a sidebar.
