Abstract
A system for processing calls based on call attributes includes a call screening processor arranged for receiving a call setup message for placing a call between an originating switch and a dialed number. The call setup message contains basic network information including at least the number dialed and information related to the originating switch. The call screening processor matches the basic network information with data in a database in response to receiving a call setup message. The data in the database identifies call attributes of the call setup message based on the data matched to basic network information. The identified call attributes comprise call attributes comprise at least one of trunk ID, member ID, and destination. The call screening processor then processes the call setup message in accordance with the call attributes by appending data to the call setup message or altering the call setup message.
