ABSTRACT:
A communication system receives a call to a called number. The called number includes a destination number and a correlation code. The communication system routes the call to a destination based on the destination number but not based on the correlation code. The communication system transfers the correlation code to the destination with the call. The communication system receives a query from the destination indicating the correlation code. In response to the query, the communication system retrieves information from a database using the correlation code and transfers the information to the destination.
