I hope someday the response time for emergency cell/VOIP calls gets to be the
same or better than landline calls. But, for now, when you call 911 from a
cell phone or VOIP phone, your call gets routed to a service provided by your
phone carrier who then confirms your location, possibly using an E911 location
database populated with physical address information you've provided in the
past, and then routes the call to the appropriate local dispatch facility.
Thats one to two extra "hops" compared to calling 911 via a landline.
This is why when you're setting up an Asterisk PBX, it's advisable to have at
least a single POTS line for backup and 911 calls even if you're running the
majority of your traffic over SIP or IAX.
