The Introduction and implementation of IP Telephony
This book considers the advantages and disadvantages of IP versus traditional telephone capabilities; the book explores the unique problems posed by running this relatively new technology. Setting guidelines it enables the reader and potential buyer to distinguish when would be the most suitable time to invest or choose the best technologies for their organisations. The book also provides in-depth coverage of the topic using several case studies, e.g.: Performance and voice quality considerations, Network architectures to support voice over IP and Social impacts directly related to IP Telephony.
This magazine article describes how IP telephony is taking a firm hold in the world telecommunication market for a wide range of applications including telemedicine. Using telemedicine as an example the paper discusses and analyses the implications of IP telephony on the evolution and deployment of e-health.
Skipping needless history, chitchat, and math, Collins gets right down to solutions with solid information on purposes and uses for VoIP in today’s society. For technicians and those like me (myself being a person with minimal knowledge) this book gives a well organised description of VoIP and provides an understanding of this emerging communications opportunity.
This article gives an overview of IP Telephony markets in 1999. It presents a catalogue of carriers, equipment manufacturers, and users; and how IP Telephony can be expected to affect each. It also gives advantages and disadvantages (less reliable, more methods defraud provider, lacks established standards in protocols) of IP Telephony networks over the PSTN. Gives effects strategies for service providers and vendors (major players in one space can enter another, shake up existing structure of internet and telecom markets)
This book evaluates communications and its importance in the 21st century. It provides an insightful and comprehensive examination of current and emergent technologies, in this case IP telephony. Furthermore this easy-to-read book helps the reader to understand the benefits, applications, social approaches and regulatory issues that will shape our understanding and acceptance of IP telephony in the coming years.
Throughout this article Stergios educates the reader on the primary benefits of integration of voice and data networks. One such benefit that Sterios approached is the realization of savings in financial and managerial resources. Although an interesting read this article tends to be one sided as Sterios does not touch on the disadvantages that affect this new technology. The most important aspect of this article is how Sterios provides an overview of this new technology and it uses in the workforce. Stergios also examines and explains the applications used by this new technology e.g. Web Attendant, Intelligent Call Distribution.
When this book was published in 1999, IP telephony was the hottest internet application. Once a guest on telephone lines, the Net now threatens a take over its host’s principal function: voice-to-voice communication. This book outlines the basic concepts of IP telephony and has attempted to become the direct line to Internet telephony answers. Marcus has given the reader a basic understanding of the technology and its cost, he has also touched on the implications and effects on society when implementing this new technology.
Gary in detail provides an overview of IP Telephony. He makes claims latency will improve with time over the wide area because gateways will improve, companies are deploying gateways on private networks, and internet is being developed with QoS support. (What this means in English) is the quality is still at a lower standard, to improve and expand on this technology firstly some irregularities need to be rectified. DTMF doesn't travel well across the internet, so gateways must detect digits locally, suppress their transmission, and then generate them on the remote side. Open systems are good because they generate competition which leads to low prices and innovation.
This book provides a hands-on guide to the theoretical and practical aspects of today’s voice communications technology. Bhumip emphasises the importance of modern telecommunications in the commercial sector. Aimed at industry professional Bhumip gives a detailed explanation of the design and architectures for Voice over IP while covering important implementation features. Bhumip doesn’t stop there he also discusses what this technology will do for future business; furthermore he provides an insight to what this technology will do to technologies that are widely used today e.g. telephones.
In this article it is apparent that fear still remains amongst the large companies going completely IP dependant. Finance brokerage Merrill Lynch is still wrestling with IP telephony and is yet to make a final decision on widespread implementation. The company is in the process of changing yet is doing so in a very cautious manner. Merrill Lynch like many other large companies depends on new technologies and the use in day to day running of their business.
