Abstract: Equivalence classes are used to determine how groups of call participants are distributed among remotely situated conference rooms. A roster of conference call participants is distributed for display by communication devices the participants bring to a conference room. The distributed roster contains at least one indicium by which the possession of an attribute, by any conference call participant in a room can be confirmed by other conference call participant(s) using a communication device. After entering a room, at least some participants use a communication device to access the roster and indicate, to a server, that at least one other participant on the roster possesses an attribute of significance to conduct of the call. Participants are assigned to groups and the groups are merged based on the presence of participants possessing an attribute or set of linked attributes. The server assigns the participants to respective groups for selective treatment.

Abstract: The system and method determine an activity associated with a user. An action associated with a media type of the activity or a role of the user within the activity is determined. For example, the activity can be how much the user talks during a conference call or if the user's role is that of a moderator. In response to determining the action associated with the media type of the activity or the role of the user within the activity, a presence state of the user is modified. The modified presence state is then communicated to a second user. This allows for a more accurate presence state of the user. It also allows other users to make contact at times where the user is more likely to communicate.

Abstract: Disclosed is a system and method integrating two different conferencing systems through an automatic mapping mechanism. Conference across two different systems are automatically connected without users in both systems being required to be provisioned.
