It would be great if I could enter a shared conference room and "take over" an Icon with my user account temporarily. That way, the far end would know that Scott Rankin was calling as opposed to "Conference Room ABC".
There are a number of ways to do this, but seeing as I always have my Iphone with me, perhaps I could use the mobile app to launch calls and connect from the conference room in which I am physically present. (This is possible today, but requires escalation/muting/disconnecting etc., perhaps we could produce a cleaner user experience that is effectively doing the same thing in the background). Taking it a step further, perhaps the PhoneHD UI for the Icon could be mirrored on the mobile app.
