Useful for remembering what calls were business calls or for separating calls made by roommates. Not secure, of course, but there are many applications for which this is okay. Both Sprint and Centrex allow you to do this. Except that with Centrex the account codes can be any lenght, and your phone bill is sorted first by account codes, second by date, third by number. You can also get your bill in machine-readable form. MIT Does this for long distance phone calls billed to MIT account numbers.
