I'd like to dedicate this book to my wonderful family. To my wife, Sharon, for giving me the time (and space) to finish it. She has the patience of a saint (not just on this book but always). I promise you don't have to remind me anymore. To my daughter, Rosie, for always being right, and to my son, Jamie, who also teaches patience. We still make a great team!

Wow, what a journey from the days of Lync Server 2010, when Nathan Winters asked me to co-author our Mastering Lync Server 2010, through the next release and now to Mastering Skype for Business 2015 on my own. Nathan's role has changed to focus more on the cloud, so, sadly, he wasn't able to contribute as much to this one as with the previous books.

Thank you to the many readers of the Lync books who have gotten in touch either via email or direct meetings at conferences and user groups and to the other customerswithout your feedback and ongoing support, I wouldn't have gotten to book 3! Keep the feedback coming (even the bad constructive stuff!).

Throughout the process, I have been supported, guided, and mostly cajoled by the great team at Sybex. Several of the original editors have moved on in the five-year journey to this edition but have been ably replaced by Ken Brown, Grace Davis, Alexa Murphy, and Christine O'Connor. All have been responsible in some way to take the scrawls that I have pulled together and turn them into something readable. Any errors are certainly not their fault. There are many more nameless (to me at least) people at Sybex working behind the scenes, who also deserve thanking.

Speaking of which, no technical book can be released without thorough cross-checking, and for that I am extremely thankful to Martin Rinas, our technical editor, who spent many hours going through the material and replicating the examples to ensure technical accuracy. In the past I've been the one correcting him, but things have certainly swapped around now.

Some vendors have provided test devices and support and in some cases have contributed directly to chapters with content. Thanks to the following:

• Actiance: Robin Smith
• Kemp: Barghav Shukla
• MindLink: Howard Travers, Annekathrin Hase, Dalia Valkiunaite
• Sennheiser: Charlotte Gaskin, Steve Bailey
• Snom: Lesley Hansen, Alison Tetlow, Hoang-Hoa Nguyen

My thanks go to all involved in helping to create this book.

My advice to others: For anyone interested in learning more about or swapping UC war stories (or even those who just fancy a beer), join your local UC user group. These groups are invaluable resources both for learning and for networking. Catch up with these people; they don't bite!

Keith Hanna started university life at Sheffield University studying software engineering but finished by graduating from Queen's University, Belfast, in computer science. His first real job was with Lucas Aerospace as a software developer working on aircraft engine control systemsit wasn't rocket science, but it was close! Moving to England from Ireland, Keith helped to design and deploy a communications system for the emergency services, but found his calling in Windows-based application design and support, eventually making his way to Microsoft, where he stayed for eight years, working in a number of roles from engineer to consultant to architect. He left in November 2014 to start a two-year study period for an MBA, while picking up small pieces of Skype for Business consultancy and training work.
