Integrating Communication Services

The need for communication services which span multiple communication technologies is growing. Communication services are being developed in three areas: in the public switched telephony networks (Intelligent Networking), on the Internet in the form of integrated multimedia, including Voice-over-Internet, and in private switched telephony networks (enterprise CTI applications). This paper shows that is plausible to create unified services which span the Internet and public switched networks and goes on to describe Nexus, an architecture and prototype for integrated communication services.
