Microsoft offers several flexible licensing options that allow you to scale Lync to your business’s specific Unified Communications needs.
: A license must be assigned for each instance of the server software that is running the front-end server role—all other roles do not require a license. Lync Server 2013 is licensed in one edition for all deployment scenarios.
: To access the Lync Server 2013 services, a Client Access License is required. Three CALs are available for Lync Server:
- Lync Standard CAL (to use IM, presence, one-to-one audio, and video; Skype Connectivity)
- Lync Enterprise CAL (to use meetings - audio, video, and web conferencing)
- Lync Plus CAL (to use enterprise voice features)
Enterprise CALs and Plus CALs are additive to the Standard CAL. CALs are available as either Device CALs or User CALs.
: Two USLs are associated with Office 365 and Lync Online. Plan 1-provides Presence, IM, peer-to-peer VoIP/Video, and Skype Connectivity; Plan 2 adds Lync Meetings capability.
: Lync 2013 client licensed via Office Professional Plus (and is also available as a standalone). Lync Windows 8 client is licensed via Windows Store and other mobile clients are available via the relevant platform store. Lync Basic 2013 client licensed via download from Microsoft.
