911 Service and VoIP

Everest cannot be POTS for 1 simple reason.  The signal comes in over
rg6, to a 'network interface device' where its converted to your
typical analog signalling.  The difference between Everest and other
PSTN terminated VoIP carriers is that Everest doesn't give you a
portable hardware endpoint.  They know your location, and its
registered with their 911 service.  With other VoIP carriers (such as
Nuvio/Vonage/Skype.)  You can have hardware endpoints, and/or
softphones.  While you may have an 816xxx number in kansas city, you
can drag it to Japan without having to update your address information
with the carrier.  This is probably the largest hurdle in the carriers
providing 911, outside of the fact that getting interconnect
agreements lined out with 911/e911 carriers takes time, and money.

There is an important distinction to make when talking about VoIP,
PSTN, 911 and e911.  911 does not provide address information to the
911 dispatcher.  e911 is the service that provides registered
addresses to the e911 dispatcher.  e911 functions by doing a lookup on
the originating telephone number and cross referencing with ALI/ANI.

More information can be found at http://www.fcc.gov/911/ which
references 911, e911, and 'mobile-satellite' 911.
