摘要 <p>Systems and methods are described that facilitate a conference call between a plurality of communication devices. The method may comprise: providing a first primary communication device; providing a second primary communication device; providing a conference call controller; establishing a first control link between the first primary communication device and the conference call controller; communicating first identification data between the first primary communication device and the conference call controller via the first control link; establishing a media link between the first and second primary communication devices via the conference call controller. In certain embodiments, the first identification data corresponds to at least one participation level of the first primary communication device with respect to the media link. The method may further comprise establishing a second control link between the second primary communication device and the conference call controller; communicating second identification data between the second primary communication device and the conference call controller via the second control link; wherein the second identification data establishes a participation level of the second primary communication device with respect to the media link.</p>
