BE6000 licensing is based on licensing users and unassociated devices. An unassociated phone still consumes the "User Connect License" that is required for that type of phone. You are correct in saying that the MD server does support up to 1200 devices, so as long as you are licensing and deploying no more than 1,000 users (think total and configured licenses/users) and 1,200 devices... Then you are in good shape. I presume that you are using Cisco Prime Collaboration Provisioning (PCP) instead of the older UPM. With CPC, you can add phones and users into UCM and they will be "synced" over to CPC at the next configured sync schedule. No problem. It is still a good idea, from a change management perspective, to add/move/change user services in CPC. It will keep track of everything that has been done to/for a user.
