While Voice over IP (VoIP) adoption has not yet achieved critical mass, it is expected to grow at double-digit rates for several years. How telecoms and cable operators pursue the emerging VoIP market will have far-reaching implications for their future subscriber market share and company profitability. This paper briefly examines the factors in VoIP adoption, followed by how these companies are pursuing VoIP at this point, with some near-term recommendations. However, one of the largest drivers of success and profitability will be how service providers adapt their Business Support System and Operation Support System (BSS/OSS) infrastructure to address the different customer and cost structure needs that VoIP entails.

All facets of IT and business communications are being drawn together. It's a concept called convergence--a term that defines many things, whether talking about blending all types of network traffic onto a single infrastructure or incorporating applications and functions into a single centralized device. What makes convergence particularly compelling is the promise of cost savings through the utilization of integrated multi-service communications devices and singular network infrastructures. But even more importantly, convergence enables new applications, processes and services. Small businesses stand to benefit from this trend towards the consolidation of communications, particularly through the advent of familiar computing devices that can support and/or incorporate multiple processes and applications. While on the communications side of things, the true blending of voice, data and ultimately video delivered through a single IP-based infrastructure is a promise unfulfilled, convergence of voice and data functions through singular devices that leverage traditional circuit-switched and "packetized" methods is now a reality.

This paper presents a discussion of the impact of the Internet Protocol (IP)technology on the potential disaggregation of international as well as domestic telecommunications markets.The key underlying protocol structure that makes the Internet function is the Transport Control Protocol/Internet Protocol, TCP/IP protocol suite. This protocol allows for the easy and ready flow of data from one user to another by agreements at various levels of the network to handle, process, manage, and control the underlying data packets. Protocols such as TCP/IP will be the heart of the evolution of the Internet. Various protocols are focused as it is applied to multimedia and new access methods.

This white paper examines third-party call control (3PCC) and its application to new services. The evolution of networks and services that has driven the need for 3PCC capabilities is examined along with some of the new service concepts that may make use of 3PCC. Also discussed is ongoing work within Lucent Technologies in the area of 3PCC and service concepts that make use of 3PCC.

The power of a systems approach is that each new application - video, Web, or telephony - is just another media type rather than a different communication medium. Voice and video are woven, along with other types of data, into the fabric of a converged network. Intelligent devices are automatically given rights and priorities and the applications themselves can intelligently communicate with the infrastructure to meet the constantly changing needs of the system as specified by the organization. This paper will highlight the many special features that customers can gain when they deploy Cisco IP Communications on a Cisco IP networking infrastructure - and it will demonstrate the unique value that this systems approach delivers to customers.

This paper outlines the growth of Internet Telephony from its beginnings, focusing on the market and its potential to mature far beyond the niche application phase. Internet Telephony has evolved to become a key platform for realizing the long-promised benefits of voice/data convergence and the merging of the Public Switched Telephone Network (PSTN) with the Internet. This paper also outlines the requirements of an Internet Telephony network and the advantages such a network would bring as a new infrastructure projected to evolve alongside current circuit-switched technology and today's Internet' and converge with them in the near future. The paper concludes with a look at the key concepts and assumptions underlying the evolution of this new infrastructure.

As voice, video, and data networks have begun to converge, more organizations are seeing the value in deploying IP business communications solutions, including IP telephony, unified messaging, voice mail, customer contact solutions, and audio, video, and Web conferencing. Questions about these technologies have arisen, as well as some common myths. This paper describes the facts surrounding these myths and provides information that can help you make an intelligent decision about deploying a converged network and IP Communications solutions.

Studies have shown that at least 60 percent of human communication is nonverbal--conveyed by hand motions, facial expressions, and body language--so a video image that enhances an audio conversation is a tremendous asset. Until recently, however, video telephony and conferencing systems have been expensive and difficult to use. The networks used were not architected for video, so the quality was poor and the pictures were grainy and jerky. Despite the lofty promises of converged IP networks that could seamlessly transmit voice, video, and data, only about 2 percent of today's meeting rooms are equipped with videoconferencing equipment, much of that still running over ISDN, and video is almost nonexistent on the desktop. That's changing fast with the introduction of Cisco CallManager Version 4.0. This mature, IP-based business communications system is the heart of Cisco's video telephony (VT) solution. Along with the new desktop product called Cisco VT Advantage, Cisco CallManager 4.0 adds video telephony functionality to Cisco IP phones. Cisco's video telephony solution enables real-time, person-to-person video sessions to be transparently added to telephone calls and conferences. Video telephony is now simply a phone call.

The term "Next Generation Networks" is seemingly very broad indeed. Almost any development in networking could potentially be placed under this banner. In fact, the definition used by ETSI’s NGN Starter Group places the emphasis on providing operators with a step-by-step manner to create, deploy and manage innovative services.

However, NGN is more commonly associated with voice – a vision for the future of packet-based voice networks as part of the evolution from today’s TDM circuit switched voice. This makes sound commercial and technical sense. For the majority of operators offering a mix of voice and data services, voice is still contributing over 80% of revenues. Besides, data networks have embraced the requirements of packet-based networks from the outset.

The Voice Web is happening now. A growing number of companies are moving at Internet speed to aggregate services (unified messaging, long distance, shopping) and Internet-based content (stock quotes, movies, Yellow Pages) and make them available over any telephone. Enterprise and e-commerce companies see tremendous opportunity to expand their customer reach to the vast number of global phone users, and they’re engaging the help of infrastructure providers to voice-enable their content and services. The availability of standards-based technology and products will fuel the rise of Voice Web services in the same way that industry standards enabled the rapid growth of the World Wide Web. This paper is intended to provide a basic understanding of the Voice Web and give an overview of the kind of services businesses and consumers can expect. After reading this paper - enterprises, telecom service providers, Internet, and infrastructure companies will understand how they fit into the growing Voice Web ecosystem.
