CX600 appears as "Speaker Phone" instead of "Handset"

We have CX600's USB tethered to their Windows 10 computers running Skype for Business 2016 connected to a Lync 2013 back end. A few users noticed that they have to press the Answer button instead of just picking up the handset to speak to a incoming caller. The difference is that when they select their primary device in Skype for Business, it shows "Speaker Phone". When it's operating correctly, it shows up as "Handset". I can get it to switch to "Handset" if I power cycle the CX600 while the user is logged on. It will revert back to "Speaker Phone" if the user reboots their computer. Here's what I've tried:


1. Remove the CX600 drivers from Device Manager.

2. Remove the sign in information from Skype for Business.

3. Switch to a different USB port.


If another user logs onto the same PC and we "Switch User" on the CX600, it show up as "Handset".


Is there something else I can try?

Hello VictorE,

Polycom and other manufacturers produce these optimized for Microsoft® Lync® or Skype® for Business devices after a reference design and the embedded OS running on the phones is provided, supported and maintained by our partner Microsoft®.

You therefore may want to reach out to the Microsoft® community and / or Microsoft® support directly instead as this is the most direct and efficient path.

Polycom is unable to add any new features into the functionality of these CX Devices
