Here is a method to list all the DN's (Used and Unused) in CCM;
Route Plan Report
The route plan report lists all assigned and unassigned directory numbers (DN), call park numbers, call pickup numbers, conference numbers, route patterns, translation patterns, message-waiting indicators, voice mail ports, and Cisco CallManager Attendant Console pilot numbers in the system. The route plan report allows you to view either a partial or full list and to go directly to the associated configuration windows by clicking the Pattern/Directory Number, Partition, or Route Detail fields.
In addition, the route plan report allows you to save report data into a .csv file that you can import into other applications. The .csv file contains more detailed information than the web pages, including directory numbers for phones, route patterns, pattern usage, device name, and device description.
I will look at this again. I think I ran this a while before but I couldn't find out if a user had logged in recently is really what I'm after. I'm trying to findout if an assigned ext has had no activity (ie: never logged in or used) so I can free them up for some new users that are coming into my facility soon. I will give this a look again. Thanks as always.
Sorry, I don't think this report is going to help you at all :( And I don't know of any "canned" report that will. This will entail some serious detective work on your part. The only place that is going to show Login/Logout activity is in the EM Trace Files. So if you suspect that a user is not making use of a DN, you will have to look here.

Or like suggested you might be better off looking in CDR/Art for calling patterns associated with the "suspect" DN's.
