 Phone Power is EVIL!
I signed up for PHONE POWER on a promotion for 10 a month or something. I paid $44 to send the adapter. I never got the damned thing to work and they were NO HELP. They were surly and rude -- totally condescending! After the promo I sent their adapter back after the promo ended, for another $8 or soI then got an email from them saying that they didn't get the power plug for the damned thing and billed me another $99.99!!! I know I sent the thing in, I put it together, left it, put it back in the box and sent it back. I don't have the thing in my house! SO I PAID $44 + $8 + $99.99 = $151.99 for no phone service.

 Nice introduction to VoIP
provided me a smooth introduction to the various components that make up a VoIP network...the projects at the end of the chapters were very good to guide you through the domain.
A very thorough introduction
I can't say this book will answer every question you might have about every piece of VoIP hardware on the market today, but it does a pretty good job of building an understanding of the core concepts shared amongst all the brand names so that you can make the jump from general to specific without too much hair pulling. If any specific product is given more attention than others, it's Asterisk, but that's not only welcome, it's unavoidable given the subject matter. The treatment it receives here also beats the everloving tar out of the O'Reilly book dedicated to Asterisk exclusively.
 Good choice for investigating VoIP for your organization...
It seems like Voice over Internet Protocol, aka VoIP, is starting to become much more mainstream. Not only are businesses switching over, but now you can set up your home phone access to use VoIP (aka "broadband") technology. Ted Wallingford has done a nice job in explaining the business side of the possibilities in the book Switching to VoIP - A Solutions Manual for Network Professionals.

br /I think the biggest thing to keep in mind when approaching this book is the target audience. While there are a few books out there on "internet telephones" that talk to the consumer, this isn't one of them. The tag line of "for Network Professionals" is the key here. While you don't have to be a network guru to read this book, some level of familiarity with network and telephony concepts would help. Someone either working with the communication systems in a company or heading up a communications department would be a perfect match here. You'd probably even do alright if you just have an interest in the subject, as Wellingford does a good job taking what can be complex material and making it understandable. An admirable task in itself...
br /
br /What makes this book stand out from other books I'd expect to see is that it doesn't just dwell on jargon and theory. There are a number of projects included in the book so you can get your hands dirty actually working with the technology. Add to that the fact that the author uses an open source PBX system called Asterisk for the exercises. So now you have no reason in terms of cost for not diving right in.
br /
br /Although I'm not necessarily the target audience for this book, I'd have no problem recommending it to someone looking for material that covers this subject. The book is very well written, and after finishing it you should have a very firm grasp of the essentials. You might even know enough to start yourself on your next career path... :)
Great book
This book provides a comprehensive look at not only VoIP, but all related legacy telephony systems it may interact with or replace. A wonderful resource for anyone considering a VoIP deployment either at the office or at home. The technical detail and background the author provides in his examples and background information is incredibly helpful. I definately recommend..
