Abstract
A method and exchange unit in a telecommunication system for differentiated treatment of calling subscribers special calls includes separating from normal calls according to information contained in the dialed number, i.e., the routing number. If the call is determined to be a special call, the routing number is modified by adding a new digit string to the routing number depending on a subscriber associated parameter. The modified number is then evaluated for further treatment of the call.
