Is Lync Server a new product?  Yes and No.  Lync Server is the successor to Microsoft Office Communications Server 2007 (and R2).  Lync Server takes OCS much farther and adds all the additional functionality needed for companies to think about replacing their PBXs and adding true Unified Communications features.  You should not think about UC as a VoIP product.  While that is a huge part of it, UC is the merging of all communication modality types into a unified user and client experience.  UC is designed to transform business processes and enable businesses to be more efficient and productive.  Lync Server 2010 is the answer!
