Screen phones for interactive services

This paper elaborates on the role and evolution of screen phones for the deployment of interactive services on the Public Switched Telephone Network (PSTN). Today, and for the next few years, Advanced Screen Telephony remains a means to enable the Public Telephone Network Operators to implement new services and offer them directly to the customer. With a modest investment in new equipment, they can create a highly loyal user base through the deployment of a variety of new services tailored to the needs of large communities of individual users.
