After rolling out Skype for Business 2016 with Enterprise Voice as part of the Office 2016 suite, we discovered a weird UI issue. This is nothing but a display problem, but can still be a little distracting and annoying!

On a certain call type – incoming PSTN calls – the little active call window would flash. This took some testing to realise, as logically there shouldn’t be a corellation with how a call got to your Skype for Business client, and a display issue with a call window; but it was repeatable time and time again, on multiple PCs with different logins.

I then found a Technet thread on the issue, but this was for the older Skype for Business 2015 client, which is pretty much a reskinned Lync 2013 client. That patch wasn’t applicable to Skype for Business 2016.

I then decided to log a Microsoft Premier case, which was rather quick and after showing them the problem and waiting a few days, they came back to say the problem was planned to be fixed in the Skype for Business 2016  – December 2016 patch.

We’ll see what happens in December and I’ll update this post, but in case others discover this issue, it’s not you and you’ll need to wait a few months :)
