Microsoft Lync 2010 stand-alone client through the Microsoft Open Government Program.

Microsoft Lync (formerly Office Communications Server) ushers in a new connected user experience transforming every communication into an interaction that is more collaborative, engaging, and accessible from anywhere. For IT, the benefits are equally powerful, with a highly secure and reliable system that works with existing tools and systems for easier management, lower cost of ownership, smoother deployment and migration, and greater choice and flexibility.

Microsoft Lync 2010 stand-alone client is used to interact with Lync Server. You can connect without this product through a web browser, however with limited functionality. This application allows the user to install the full Lync capabilities on a PC.
