I second that about having 4 digit DN lengths....it's also helpful if you have DID's, you can match up the last 4 digit numbers of the DID's with the extension numbers in most cases. You may have to do some rearranging with the parked code extension number. I chose my DID numbers in the 63** range, so all of my internal extensions are 6386, 6389, etc.
