How to block calls and meetings in VDI on network level
How can I block all Teams audio and video when running in a VDI? We're about to deploy Teams in our VDI environment (Vmware Horizon, Windows 10, no Citrix) and don't want the users to be able to do audio/video, because that's a huge performance hit on our infra/network. But when used outside the VDI environment, like from home or on a mobile device, audio/video is fine. So Teams user policies can't help us here. I looked at the Teams desktop app and found a few json files with a lot of settings, but wasn't able to use this and don't know if any of these setting controls the use of audio/video. Now I'm trying to find out which tcp/udp ports and IP ranges to block on our firewall (for the VDI subnet), so users can still use Teams for chat / documents, but not for audio/video. I've tried to block UDP 3478-3481, and also 50000-50059 (source and dest), but to no avail. I can still join a meeting. Can somebody help me to figure out which ranges to block?
