Abstract: A system to adaptively control multimedia communication sessions includes a mediator unit in an intermediary communication position between two or more remote clients and a media infrastructure. The mediator unit includes a receiver, a transmitter and a control processor that controls the receiver and the transmitter. The mediator unit communicates remote clients across a communication network, where the first client initiates a communication session and the mediator unit assigns a unique session identifier to the communication message. Additional remote clients send join requests including the unique session identifier, and the mediator unit acts as a back-to-back user agent to pass messages between two remote clients of a two-client communication session.

Abstract: A method for correlating multiple collaborative sessions occurring on multiple single-modality systems includes creating a respective collaborative element containing metadata about each respective collaborative session, associating each collaborative element with a corresponding collaborative conversation, providing an overlaying control plane across the multiple single-modality systems, computing and storing conversational context of user actions within the collaborative sessions. The method further includes performing data aggregation of data within the multiple collaborative sessions, publishing one or more messages providing information regarding changes in the multiple collaborative sessions, switching modalities by entities participating in one or more of the multiple collaborative sessions, wherein the entities can follow session conversations by accessing the published one or more messages, and embedding a link in a single-modality system user interface referring to a previous session.
