Can't receive a PSTN call when LBR is enabled for Skype for Business 2016 in a VDI environment

In a Virtual Desktop Infrastructure (VDI) environment, when you use a Skype for Business 2016 client in a virtual machine, the client will use the subnet of the virtual machine to register. If this client is in a Location Based Routing (LBR) enabled environment, you may be unable to receive a PSTN call because the server that hosts the client thinks the location of this client isn't valid for PSTN calls. In addition, the call will go to your voice mail.

To fix this issue, install the March 5, 2019, update (KB4462190) for Skype for Business 2016.
