    Answers the basic 'why change from something that works' question

    If there is a service more reliable than the phone service in the United States, then I have yet to encounter it. It is so reliable that we are astonished when we pick up the phone and there is no dial tone. Therefore, when IP telephony (IPT) is touted as a replacement for the traditional phone service, managers are very skeptical. Nearly all of the major questions concerning the advantages of IPT are answered in this book, which is written at the level of the non-technical manager. Most of the points are made by simple examples of how IP telephony is superior to the traditional form of phone service. Diagrams are often used to illustrate the basic points, largely to explain how connections are made. Properly implemented, IP telephony can increase the efficiency of your operation and I strongly recommend this book as a primer on how it works and how it can save you money.

    IP Telephony Unveiled

    IP Telephony Unveiled ISBN 1587200759 By Kevin Brown Do you have questions like these? What is IP telephony? What is Voice over IP (VoIP)? What is an IP telephone? Is this a new PBX system? How can I use IP telephony and make it work for me? Where Do I start? If you do have these and other questions then Kevin Brown and Ciscopress have the answers for you. The book is IP Telephony Unveiled ISBN 157200759 by Kevin Brown, and Published by Ciscopress. It will answer all of your questions without being to technical. In Ciscopress own words ¿This volume is in the Network Business Series¿. And just what is this Network Business Series? It is a series that explains a technical subject without all the geek speak. Don¿t let that fool you, the subject is well covered, and all of your questions will answered. But that¿s not all, it also gives direction to get IP Telephony started the right way at you company. The book will help you avoid pitfalls, (if you will follow Mr. Brown¿s directions), and explains the differences between your PBX and IP Telephony. It also tells you the many amazing things you can do with this new Telephone (client) on your network. If you are a hard core techie wanting to know the nuts and bolts of how to set-up and maintain an IP telephone system then I would suggest looking at the technical books that Ciscopress has to offer on this subject. If you are a tech, manager, or executive that needs information to make a decision about IP Telephony at your company, this is the book for you. Even though it is not a big book, (only 170 pages including the index), it is full of information and the experience if the author. The book is divided into eight chapters. The first chapter covers the similarities and differences of a PBX system compared to an IP Telephony system. It also covers the convergence of the phone and data network system. Chapter two explains the advantage of IP Telephony over the PBX. It also shows the potential of IP Telephony. Chapter three cover the fact that you keep all of the function of the PBX and add so much more. In chapter four called ¿If this isn¿t a PBX, what is it?¿ Mr. Brown gives real world examples of IP Telephony system proving this is not just a phone but a client on the network. To me chapters¿ five thru eight is worth the price of the book. In these chapters Mr. Brown shows his tremendous experience with IP Telephony. The subjects in these chapters are topics such as, sample business cases, ROI, ROI real-world examples, planning, and the seven steps to a successful IP Telephony experience. Mr. Brown also covers what is coming in the future. Kevin Brown shows he knows his stuff , and once again Ciscopress comes up with a great book. I know you will enjoy this book. I did.

    Excellent Resource for Decision Makers

    IP Telephony Unveiled (ISBN 1-58720-075-9), indicates that after reading this book you will ¿understand how IP Telephony can change your business¿. I submit that this book does a good job in providing this information. For the last four years, I have worked in the pre-sales, engineering, implementation, and post-sales phases of IP Telephony projects. This book does a good job in expressing many of the thoughts I have had in dealing with my sales teams¿ promises and customers¿ expectations. This book addresses the paradigm shift that is necessary to fully embrace IP Telephony as a whole. If a manager is looking at just a PBX replacement, then IPT will never fit their bill. Rather, one must be looking at going beyond the PBX model. It provides a minimal amount of technical information, focusing rather on business reasons and drivers to move to IPT. The author begins with a coverage of past attempts to use the PBX model to provide convergence and the shift in thought that brought about IPT and the reasons the author feels it will be successful. The author, Kevin Brown, then moves into objections, decision makers will present when deciding on moving to IPT. Brown provides plenty of anecdotal stories about how others have addressed these types of objections. I found these beneficial. I plan on using some of his stories and examples in future sales opportunity. Another thing I like about Brown¿s book is that he presents many examples of how IPT has been used in a number of vertical markets. He does this by showing applications that are accessible through the phones and the business problem it addresses. Additionally, he addresses issues one will face once the decision has been made to go with IPT. He talks about how the organization should look at ROI. I like this as he again looks outside the box, to show the value of IPT in more than just dollar signs. He is honest in the investment needed to undertake IPT and also the hard and soft benefits that come from IPT. He also talks of the need of doing a voice readiness assessment (VRA) and the issues that may come up in the process. These issues include QoS, the need to upgrade WAN links, and router upgrades and/or replacements. Lastly he talks about the importance of choosing the right, presumably, Cisco partner to undertake the project. This section also includes the seven steps, Brown feels, will lead to a positive experience with IPT. Lastly, the author presents a view of the future we can expect with IPT. The only thing I wish the author would have done is presented more of a Cisco-centric view of IPT; this is after all a Cisco Press book. He mentions Nortel and Avaya a few times. He passively talks of Call Managers and Cisco¿s line of phones. Maybe the vendor neutral mentality was intentional as to not just seem like a marketing mouthpiece for Cisco¿s AVVID. Other than that minor objection, I wholeheartedly recommend this book to salespeople pitching IPT, managers being pitched, and technicians who are involved in both sides of the sales cycle. This book does provide the information to show how IPT can impact businesses.
