Abstract

See full text

It is an object of the present invention to provide a general-purpose media layer for a distributed feature system. In accordance with an embodiment of the present invention, a distributed feature system environment is disclosed in which paths carrying media, e.g. voice or text, are fully separated from signaling paths. A plurality of media processing components are utilized to establish media channels separate from signaling channels and wherein each media processing component is assigned to one or more feature components in the distributed feature system.
