> How exactly does Asterisk provide E911 service??

It doesn't do anything with 911. You tell * what to do when someone
dials 911 via your dialplan.

To avoid legal issues down the road, I'd suggest handling it via a
local pstn line (one way or another), and install a Red Phone with
a normal pstn line for emergency use. (The pstn line for the Red
Phone 'could' be used for incoming faxes as well, and when combined
with something like an spa3000, will handle * to pstn 911 calls.)
