Abstract
A multipoint control unit coordinator (MCUC). The MCUC tracks all conferences in a telecommunications system and determines how they can be best configured and modified over time. The MCUC instructs multipoint control units (MCUs) to break down and reconfigure calls, if necessary. A MCUC according to an embodiment of the invention maintains a database of all the MCUs in the system, a measure of processing coding resources, and a geographical location. When two parties seek to add a third in a conference call, the MCUC determines coding resources, geographical locations, and determines the most appropriate media stream mixing location based on preferences, such as network cost or endpoint coding resources or quality. The MCUC then instructs the MCUs to handle the conference accordingly.
