Summary: Required reading for those looking to create phone services
Review: Developing Cisco IP Phone Services takes the reader through all of the steps necessary to create usable service applications. A lot of the info covered here just isn't mentioned anywhere else, including Cisco's web site. Even though services are constructed from standard protocols, creating ones that work well can be surprisingly challenging. I keep a copy of this book on my desk at all times as a reference. The user interface sections are quite useful. Spending time on how to design a service is at least as important as how one is written. On the down-side, however, I found the included code to be Windows-centric, and also wished they had included source code for the tools. But, the included information enabled me to write my own tools. I think that speaks for the quality of what you'll find here.

Summary: Developing Cisco IP Phone Services very useful
Review: I needed to get an in depth understanding of the way services for the IP Phone were developed so as to develop security policies to help protect network assets. This book gave me exactly what I needed to know. It will be very useful to anyone who wants to develop XML based services for the Cisco phones.

Summary: An IP Phone Developer Must Have
Review: I really was able to use the book as a cookie cutter for my own XML services. I found the book easy to read with great examples. The best thing I liked about the book is it didn't bog you down with a bunch of useless facts. The authors got right to the heart of the matter, and explained the steps very well. As a bonus, the tools that come with the book allow you to develop these services with just a PC and a Cisco IP Phone. Great job.

Summary: A very useful collection of information in one place
Review: If you want to develop IP phone services, this book will really help you. Almost everything that is in here is available on the Cisco web site...somewhere! I spent days searching through Cisco documents and sample code looking for answers to the "hard" questions such as "how do I know which phone is accessing my service". I found the answer in this book in a couple of minutes.The book is not for web beginners, however. It does spend a fair amount of time giving you some background in HTML and XML, but only at a very high level. Most of the examples are written in ASP, but no explanation of ASP is given. I don't think that this is unreasonable as the book is aimed at people who know how to write web applications and want to target those applications to IP phones. As the book was published in 2002, it pre-dates the latest Call Manager 3.3 release, and as such does not describe some new features of Call Manager, such as the AXL API. You do not need this information to write most applications. If you do, you can get it here: http://www.cisco.com/warp/public/570/

Summary: the definitive resource for building Cisco phone services
Review: This book contains detailed descriptions of phone-based XML tags, authentication, push capabilities, and many other subjects that cannot be found anywhere else (including CallManager texts). I was a reviewer on this book, but I'm also a user: I relied heavily on this book to help build the application that won Best of Show at the Cisco Convergence Expo in early 2002... If you are doing any development for, or integration with, Cisco IP phones then it's simple--you need this book!

Summary: No details
Review: This book has some good examples, but lacks any detail.
It skims over all the complicated topics.
Does not do a very good job at demonstrating how to build applications that integrate a web browser and an ip phone.
Very introductory.
