SYSTEMS AND METHODS FOR FACILITATING CONFERENCE CALLS USING MULTIPLE MEDIA STREAMS
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; providing a first alternate communication device; establishing a first control link between the first primary communication device and the conference call controller; establishing a media link between the first and second primary communication devices via the conference call controller; and establishing a second media link between the first alternate communication device and the conference call controller. The second media link may be established upon the conference call controller receiving a link request from the first primary communication device via the control link. In some embodiments, the first media link conveys a first media signal which is different than a second media signal conveyed by the second media link.</p>
