The database may go back decades but it's hardly comprehensive going  
forward, lacking multiple other long-distance carriers, cellular  
(including anonymous prepaid) calling, VoIP calling, computer-to- 
computer connections like Google Talk, and cheap/anonymous calling  
cards. I use a Costco calling card that costs $0.029/minute and isn't  
the cheapest available. If I pay cash for it and don't recharge it,  
it's not directly linked to me. (Hm, well, unless they track it from  
my Costco membership number! But such cards are available for cash at  
non-membership stores.) If I don't ever use it from a phone linked to  
me, it remains anonymous.

All in all, calls are recorded in many disjoint databases. And people  
seeking to be anonymous, or simply using technology or services which  
by default anonymize, won't be tracked.
