When you make a Skype for Business call with audio routed through your desk phone, you get great audio, plus: The person you’re calling sees your phone number as though you were calling from your company's main phone number. You can also place calls from the Skype for Business client using any phone near you (like your mobile, home, or hotel phone). If you have a Phone System in Microsoft 365 desk phone and your IT department has configured it to work with Skype for Business you can search for people in your organization and place calls to them from within the Skype for Business user interface, while audio for the call flows through your standard Phone System desk phone. Important: This feature is available only if your organization has Skype for Business Server 2015. Call from Skype for Business using your desk phone for audio When someone sends you a file, select Download in the IM window to update the file's icon, or right-click or tap and hold to forward, preview, or delete it. If you've ever had someone send you a file during an IM conversation, then file transfer preview is another feature of the new Skype for Business look and feel you'll appreciate. In the conversation window, chat text is formatted so you can easily see who’s talking, and tabbed conversations allow you to keep track of several discussions at once.

In the Skype Meeting window, the simplified arrangement of controls and menus makes it easy to find the command you need.

Of course, all the essential Lync features are still there-like the Quick Actions buttons, which let you IM or call a contact (and more) with just one click or tap.

If you’re a regular user of the commercial version of Skype, then Skype for Business will seem very familiar: the Contacts list, presence indicators, buttons and icons, and even the app sounds should make you feel right at home.
