NOTE — NPSTN is a free unique telephone collectors' network. NPSTN has a "billing" functionality that is purely for fun. The idea is to show you all the calls you make on NPSTN and what they would have cost back in the day. The bill is for fun, and you are not actually charged anything. NPSTN is and always will be 100% free.
