  Obviously if you have a NY cell phone and live in FL, it won't be
  accurate. That's impossible.  But I _CAN_ show where that NY cell phone
  resides in the NANPA world, or at least a rough estimate.  Sure, some
  ratecenters cover hundreds of miles, but for the most part you can get a
  good handle on where a number originates from.

  I don't care about where the device that rings when you call a number is
  located.  Privacy issues abound there.  I'm merely looking for a
  definitive source of Geo-telecom data for NANPA.

  What VoIP isn't rate center based?  Sure, billing may not be, but that
  doesn't cause an npanxx not to be linked to a physical location.  And some
  providers still do full npanxx based call decks.  Sometimes you want to
  give the customer some insight into the call -- if you don't have a name,
  give an accurate location at least (more than a state).  I know my
  provider, VoIPo, sends information like "Anytown OH Mobile" or
  similar when a name isn't available.  That's useful!
