    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.

    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.
