Abstract

1 Introduction Until now, two separate worlds have existed for tele- communication services and networks – one for voice and one for data. The voice world is that of switched PSTN / ISDN networks, which generally provide real-time services and features such as call diversions, conference and display services. Switched PSTN / ISDN networks guarantee quality and reliability in the form of constant availability of voice services for their customers. As a result thereof, this quality of service has made voice networks extremely profitable.
