CDR reporting is based on routes - not specific DN's.
In a pinch, output the CDR to an unused TTY port and use a terminal emulator such as Procomm or Hyperterm to capture it to a file* - and then you can import it into a database and build a query to find the data you need.
But as others said - the best bet is a 3rd party application that is designed to store and report the data.
* Save and rename this file often - like once a day in case the PC capturing the data crashes, reboots, whatever during data collection.
