I have a problem others have reported, but perhaps this is a more common scenario?
I log into VM on a secured environment to work. It doesn't handle voice or video very well, so I answer my calls on my Phone, which is managed by MDM and connects to my corporate Teams account. When someone calls but wants to do a screenshare, I'd need to join the call somehow from the desktop, but there's no way to do this.
I can join or schedule a meeting and then connect from my phone for audio/video and my VM Desktop for screens. But this doesn't work if you are starting from a Teams call. Further, if you try to do a screen share with the same user, it puts the Team Call on Hold.
How about creating an Add Desktop to Current Call function?
