This enterprise device client access license (CAL) can be used only in conjunction with a standard Office Communications Server device CAL. It authorizes one computer to access certain Office Communications Server features, regardless of the number of users (for example, on a shared workstation).
The features licensed through the enterprise Office Communications Server device CAL include web conferencing, voice over IP, and application sharing.
User CALs are also available. A user CAL allows one user to access Exchange Server's additional features 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).
Note: This license does not require media. Instructions for obtaining the license will be sent to your organisation email address after your eligibility has been verified and your administrative fee has been received.
- Under the Software Assurance program, customers acquire the right to install any new release of products covered in the agreement during the term of their coverage.
