Acknowledgments

The contributors who spent their very scarce time working on material for this book have my earnest thanks. These gentlemen are truly talented networking engineers, and their input and technical expertise were invaluable. Do business with these guysthey are established knowledge leaders in this new industry.

I'd also like to thank Mike Loukides, who recommended that I write VoIP Hacks (or perhaps he merely succumbed to my nagging). He edited Switching to VoIP, and he is the author or co-author of several excellent O'Reilly volumes, including the highly useful Unix Power Tools and one of O'Reilly's earliest technical books, System Performance Tuning. He's a pretty amazing pianist, too.

VoIP Hacks was edited by David Brickner. David's editing is pragmatic, politically incorrect, and to the point. I love that. I'll give David all the credit for anything good about VoIP Hacks!

This book survived the criticisms of several tech reviewers, including Kristian Kielhofner, Leif Madsen, and Jim Van Meggelen. Thank you for looking over my work; your expertise added much to the book's accuracy.

I must heartily acknowledge my hometown crowd, too. My wife Kelly and my friends at Pathway have given me plenty of much-needed encouragement. The crew at LCG Technologies is a great bunch, too. I just barely squeaked this book out thanks to my new workloadkeep up the great work, LCG. Thanks to Brian Downey of The Linux Fix for his expert Linux support, as well.
