Exactly. And that's *mobile* phones. The US still has 90%+ penetration of 
land lines *also*. It's not uncommon for a family of four to have 10 phone 
numbers dedicated to their use. That's why I say the PSTN is way bigger than 
the internet, because (A) that's not even counting addresses assigned to 
switches, which IP has to count, and (B) not even counting commercial phone 
numbers, fax lines, pagers, phone numbers assigned to modems, etc.

I'm not even sure if VOIP and cable telephone counts as part of the PSTN.
