Here is a sample from the book whose sole goal is to convince you to buy the book.


Did I succeed?



I have been working professionally with Microsoft Windows since Windows NT 3.1 was released. The first Windows NT 3.1 server I installed for a customer ran on a DEC Alpha. That should not impress you. That just lets you know that I am old.

Since 1993 the majority of my career has been focused on the implementation, support, and operations of Microsoft server products. In 2009, my boss at the time told me that I would be responsible for our company’s implementation of Office Communications Server 2007 R2. Quite honestly I wasn’t terribly excited. I had always avoided the telephony side of IT as best as I could.

However, as we started enabling Enterprise Voice in OCS, I became seduced by the possibilities of true Unified Communications. By the time Lync was released, I was voraciously reading every tidbit I could find on the Internet. We installed Lync into production in February of 2011, a scant 2 months after it was released to market. Soon thereafter my job title changed to Sr. Telecom Engineer. My avoidance of telephony in IT had officially come to an end. But I didn’t mind as the team with which I worked were rapidly converting users from old school digital handsets to Enterprise Voice enabled Lync users. By the time I left the company, we had converted around half of our users across the USA and Canada to Enterprise Voice.

I was briefly a Lync consultant and then landed at a multinational corporation where one of my primary responsibilities is standardizing the corporation on Enterprise Voice. I have worked either directly or indirectly on projects on every major continent. I doubt I’ll ever do much with Antarctica.

My personal web page can be found at On that site you will find interesting things I’ve learned about Skype for Business and Lync.

I also run the UC Now website found at This site contains an aggregation of pretty much every English-language Lync blog that is even somewhat active. As of this writing, over 120 feeds are aggregated to spit out the latest articles. For those with Windows Phones or Android devices, look for the “UC Now” app on your devices app store. There is also a version for Windows 8.1 and later.

This book should help you greatly enhance your knowledge of how Enterprise Voice in the Skype for Business world works. If not, thanks for your money and do everyone else a favor and plaster the Internet with negative reviews.

Ken Lasko did the technical review of this book.

So if something is wrong, I’d like to blame him.

But I won’t as my name is on the book and not his. As such, below is the list of corrections to the book.

  • Busy Options were added in June of 2017 and are not covered in this book.
  • The bug mentioned on page 187 (Reordering Dial In numbers) was fixed in the July 2016 Cumulative Update
  • As of CU7  (released in April 2016), Shared Line Appearance is available in Lync Server 2013.

Page 143 – The cmdlet at the bottom for the New-CsServerApplication is missing two hyphens and should read as follows:

The missing hyphens are in GetCsServerApplication and Identity

The following are only valid for the paperback version printed before April 1, 2016.

Page 253,257,258,259 should reference Figure 12-22 instead of 12-23
