We're in a Citrix/VDI environment running Windows Server 2016 and trying to get Glip and RingCentral Meetings to work.
When we installed RingCentral 64-bit, it would load a white screen and not work for users. It also installed to app data rather than to the C drive of the server.
We then tried RingCentral Classic, but it would take really long to load (if it would load) and slowed the server down too much for users to function in other applications.
I called the support line but wasn't really given an answer about terminal server/Citrix compatibility.
The use of the phones won't be needed in the VDI -- we're looking just to functionality of Glip as the main function.
