Abstract
A system for managing voice and data communications for at least one user is coupled to at least one wide area telecommunications network and includes at least a processor and data storage resources. A first bus is adapted to couple video data between the system and a video unit coupled to the system under control of the processor. A second bus is adapted to couple audio data between the system and a microphone unit coupled to the system under control of the processor, and audio data are coupled to a TDM bus in the system operating under control of the processor. A digital transmission link of the wide area telecommunications network couples the video and audio data from the system, under control of the processor. A user participates in a video call with the video data, while concurrently the user participates in a telephone call with the audio data. Voice communications of the telephone call that stay in a circuit-switched form are provided via the TDM bus, and the video call and the telephone call can provide a conference call.
