OK.  I was under the impression that the PSAP got their information based on 
ALI/ANI and not from CLID.  Are you telling me that they're looking at CLID?

Also, at least in the testing I've done, the text portion of the CLID string 
is ignored by the telco.  They only look at the number and generate the text 
based on what is in their database.  IE; If I tell my asterisk server to set 
my callerID to "test" <my home number> and call someplace, What I get on the 
  CLID display of the phone I dial is "John Fraizer" and my home number.

Since Powell has stated that we must provide E911 services, I am wondering 
what precisely is going to have to be done to do so with Asterisk.  Routing 
the call to the PSAP when someone dials 911 is the easy part.  Sending all 
of the information they want/need (much more than just CLID and something 
that is regulated) is an alltogether different story.
