In Microsoft Skype for Business 2016, consider the following scenario:
In this situation, you can't hang up or unhold the remaining call by using the headset.
- You have a USB headset which has a feature used to hang up, hold, or unhold Skype for Business calls.
- You have two calls in progress, and you use your headset to hang up one call.
After you hang up the second call, the headset doesn't send proper USB events indicating an additional call is still on hold.
