Lync Server Device CAL - Plus (Includes Software Assurance)
This plus device client access license (CAL) can be used only in conjunction with a standard Lync Server device CAL. It supports the enterprise telephony capabilities of Lync Server on one computer, regardless of the number of users (for example, on a shared workstation).
Audio, video, and web conferencing and application-sharing capabilities for Lync Server require a separate license, the enterprise CAL. To enable all features, all three CALs (standard, enterprise, and plus) are needed.
User CALs are also available. A user CAL allows one user to access Lync Server's enterprise telephony capabilities on any number of computers or other devices (for example, when an employee accesses the server from a computer at work and another at home).
License Only: This license does not require media, license keys, or setup codes.
Software Assurance: Under the Software Assurance program, you have the right to install any new release of products covered in the agreement during the term of your coverage.
