Setting Up Skype/Polycom Phones
The first time you use Skype on any computer you will need to do this. After the first time you run Skype it will automatically start when you logon. Click the Windows start menu (very bottom left corner of the screen. Looks like a window pane). Select "All Apps"
Double click "Skype for Business 2016".
Naturally, make sure your PolyCom phone is connected. Insert the USB connector into any un-used USB port on your computer. You may do this with the computer powered on OR off. It does not matter for this device.
