I'll keep this one simple. Can you remove the "Join" button under the meetings menu/active meeting pop-up on the Trio 8800s like you can the property in mumbai (http://www.hawareintelligentia.com/) new projects in mumbai (https://www.ashwinshethgroup.com) "Sign Out" button? (feature.lync.hideSignOut). In some conference rooms we couple our Trios with a Surface Hub and if they use "Join" on the Trio instead of the Hub it joins in audio only from the phone. If they join/answer from the Hub they will get both.
