1. Wired VoIP calls WILL look like current wire line 9-1-1 calls when
they are delivered to the PSAP (COS may be different).
   2. Geo routing determination within the network that supports the
VoIP call delivery is fine right up to the LGW (or whatever the entity
is for connecting to the selective router). After that, the call will be
routed via wire line techniques  i.e. dedicated trunk to the selective
router and delivery of a key to the PSAP to retrieve the ALI
information (either static record in the ALI DB or, via NCAS). If the E2
protocol/interface doesn't support it then we'd better find something
else.  
   3. Only validated civil addresses are acceptable for display at the
PSAP UNLESS the call originates from either a WiFi, WiMAX or other
wireless IP capable delivery source in which case, display of an x-y
coordinate is satisfactory along with a validated civil address for the
location of the wireless base station - this is analogous to wireless
call delivery today.
   4. The MSAG validation process will be coordinated with the 9-1-1
service providers responsible for the supporting DBMS for each ALI DB.
Whether the address information has to be validated using a manual or
automated process (similar to the PS-ALI process CER uses for the
enterprise environment) it does not matter.
