I know a 911 call is routed to a PSAP but since I was "in the business" (it was just pre-E911) I'm not sure exactly how it works today. Does an E911 call go to the same call center as a POTS dialed 911 call would go or does it go to some "private" call center who forwards it to the proper emergency service? Back then there were lots of 911 errors when calls went to a PSAP in the wrong area, wrong state or no one answered or the PSAP that was called had no idea what to do which is what eventually led to the gov't getting involved. I know it has changed, but I'm curious on how it functions now as far as call routing.
