Skype for Business

Skype for Business is an interoffice/intranet instant communication application that offers audio and video messaging services, which can replace other business tools like telephone, meeting and chat software. Skype integrates with your calendar and provides information about your presence.

Desktop installation

Follow these instructions if you are installing Skype for Desktop to a local computer. 
(Steps 1 – 5) 

Note for Mac users: As of late October 2016, the Skype for Business client is available for macOS and OS X. ISC has conducted limited testing with the Skype for Business for Mac client, and has found it to function properly. ISC will continue testing to learn more about its features, user interface, and/or limitations. LSPs may want to remind their users that Skype is also available from within the web portal as an alternative.

The Skype for Business for Mac client, as well as installation instructions, may be found here:
