But here is some of the info.
Pricing and Licensing
Lync Server 2010 follows the Server/Client Access License (CAL) model. Under this model, a Lync Server 2010 license is required for each operating system environment running Lync Server 2010. A CAL is required for each user or device accessing the Lync Server. You can acquire Lync Server 2010 CAL as standalone servers and Client Access licenses (CAL) or you can purchase the CALs as part of the Microsoft Enterprise CAL (ECAL) Suite. Lync 2010 is the client software used to interact with the Lync Server 2010 Server and is licensed separately as a standalone license, or available via Office 2007 Pro Plus and Office 2007 Enterprise.
