ABSTRACT: Notes on Advanced Voice Services (AVS), a new release in the popular Telcordia Notes series, takes you from the fundamental implementations of the many consumer services currently deployed, through the possible network architectures that support these services, to current and future trends and services under industry discussion. Based on the latest information available in the telecommunications and networking industry, this Special Report (SR) introduces the vast area of consumer services. This document, from the company with a unique legacy of expertise in this field (Telcordia has published industry requirements and standards related to voice services since the 1980s), provides the latest information on current issues and evolving activities impacting consumer services. The SR brings the reader quickly up to speed in areas of service definition and deployment, as well as ongoing issues that often impact the customer perception and acceptance of services. With Notes on AVS you will learn about:

• The current market for popular, revenue-generating services such as Caller ID and Call Waiting, as well as marketing strategies being used by providers to increase service penetration.
• The service-specific capabilities and interfaces that must be implemented to support existing services as well as newer services still in the early stages of deployment.
• Possible network architectures that support consumer services and the advantages and disadvantages that each offers.
• Potential services including Internet services, speech recognition services, and combined voice/data services that are either beginning deployment or are still in the conceptual phase.
• Ongoing issues (e.g., unavailability of calling name/number, customer privacy expectations, universal service design) that providers often must address to maintain a positive customer perception of services and support the large revenue stream offered by consumer services.
