the Compuware office in Detroit leases space on the ground floor of the main building and the adjacent build to other companies; one of the options for leasing includes phone service. unfortunately those that get the phone service from Compuware with the lease show up on all outgoing calls as calling from Compuware's main number for this site. I know this because the Detroit Medical Center has a small doctor's office in one of these spaces and all of their calls to me show up as Compuware.

if you are receiving calls from this number, it could be any of these business, and Compuware staff answering the phones is not even aware of this...
