Administrators should have the option to restrict direct calls between Room Systems within the management console. Basically, it could force end users to only contact other individual Cloud users, or dial into Virtual Meeting Rooms. It would help reduce the potential for users to call into the wrong destination when attempting to join a meeting. Ideally, we would be able to remove the Directory button/list from the phone pods, desktop app, and Icon menus, leaving only the Meetings button/list.
At the least, we would be able to hide the Room Systems from the Directory listing, which would still allow users to call individual users or add them to Virtual Meeting Rooms.
