Wow,  kinda rude don't you think?   Matt WAS Helping,  why aren't you  
listening?

Contact your state SETB and ask about connecting to their selective  
routers so you can send calls direct to the PSAPs.  You'll also need  
to update the location of your DIDs and validate them against the  
MSAG.    Normally you'll need to use IMTs to connect to the selective  
router and IMTs require SS7 with ISUP routes to your LECs STP.  You  
do have SS7 on your Asterisk box right? If you want to provide cross  
LATA E-911 then you'll need to connect  to each pair of Selective  
Routers in each LATA.  You'll also need ISUP routes to each Selective  
Router.    Go to www.nena.org and read about your E-911  
responsibilities.  Make sure you setup your Asterisk box so once a  
customer dials 911 they CANNOT hang up the phone.  You also need to  
make sure you have redundant routes to each Selective Router and  
provide a failover to a live operator in case the call can't complete  
(in short, a 911 call must ALWAYS complete to a live person).  Only a  
911 operator can hang up a 911 call...

Or,  you could call Intrado.com and save a ton of money and headaches.

Oh,  an don't forget about CALEA,  good luck with that one.

But hey,  what do I know about VoIP, SS7 and building a CLEC?  I run  
a full CLEC, with full SS7 connectivity to Verizon,  redundant routes  
to the Selective Routers for my LATA.  Local number portability  
database access, all that fun stuff.  I still outsource my 911  
traffic to Intrado.
