When you order a PRI from a CLEC they typically will dump
your CLID info and replace it with the "main" number on the
span.  You can request that they not do this and that they
pass the CLID thru.

We have been working with some of the local PSAP's here,
CLEC's and the ILEC.  In about 2 weeks we are going to do
some live 911 trials using asterisk.  

The goal is for us to set the CallerID to a test number, then
dial 911 and see which PSAP the call goes to, and if the CLID
shows up.  If it does, then some issues are resolved for us.

There is also a special circuit you can purchase from the ILEC
that is basicly a 911 T1 interface into the selective router
the ILEC maintains here.  Its a little pricey, but still worth
it.  So we could also switch calls inside Asterisk to the 911
truck directly.

In either case, the County PSAP and the state 911 director
have been very very helpful and most willing to be involved.
NENA has also been very helpfull as has Intrado (once you sign
NDA documents).

My recommendation is that if you are looking at 911 issues, 
go buy your local PSAP manager a cup of coffee and listen
to how things work in your area.  The country doesnt work the
same in all areas. 

Help educate them on how this VoIP stuff works, most are 
dealing with two full plates and trying to get Cell 911
stuff up to Phase 1, or in some cases Phase 2 standards.
