When one call 911, how is the call automatically local?

1.92K views

Hypothetically speaking, if someone is living in New York and they call 911, how does the call not go through a hospital in Los Angeles or other city from another state? How does the call automatically transfer to a local hospital in the area one lives in?

I’ll add on here, so typical cell phone triangulation is done using the 3 closest towers to get a “general” location. Phones now have a more information they can provide which 911 systems can take advantage of, pedometer, wifi hotspots, gps, things like that. Which make services like Rapid S.O.S work

For home numbers the carriers provide 911 with that information via ani,ali information. Where as with cell phones a clearing house is involved. I would give the name but it changes often.

With voip providers it’s whatever information you put in with the company (think vonage,skype) so keep that up to date.
