Abstract
When a conference bridge establishes a link line with another conference bridge to provide a global conference, a global conference application executing at the conference bridge establishes a SIP dialout with one or more remote conference bridges. The global conference application uses the XCON standard and/or the CCMP draft standard to subscribe for event notifications for that conference from the remote conference bridge. The received event notifications can be made available for use by the source conference bridge when constructing the roster information for applications executing at the source conference bridge. The received event notifications can be displayed and provide the proper diagram for the distributed conference complete with media, mode, and other information displayed. Further, the system allows the use of intelligent endpoint user interfaces to control mute, lecture mode, sidebars, breaking the bridge into sub-groups, and the like during the conference.
