[cisco-voip] [Semi-OT] E911 and legal issues

I've been down this path several times. 

What you need to do is call the local non-emergency number for the
area(s) that you need this deployed.  You will then need to work with
them to identify the actual pop that services your location.  They
usually have someone who can answer these questions and outline the
local requirements and laws.  I always make it a point to request on
upcoming changes to the laws as well, but they are not usually excited
about change.

The next step to take before looking into something like CER is to call
the local carrier.  It's embarrassing to sell a customer CER and then
find out the local carrier cannot accept dynamic ELI updates.  Usually
the carrier can give you the comparison of what is required by law and
what they can provide from the Telco's perspective.

Sorry for the off-topic, but google-ing around didn't reveal much to me,
so 
here it goes: has any one of the members of this list implemented an
E911 
solution? I have a client who needs this installed, but we do not know
if the 
configuration has to be related to legal aspects in the
state/county/town the 
company resides in. Here is what I am referring to: 

- under the old, analog system, the methodology of calling 911 had the
number 
actually routed to an emergency crew, properly trained in CPR and other
first 
emergency responder methods, who would then decide if the call had to
really 
go to 911. One of the big advantages of this method was also the fact
that 
the internal crew had full knowledge of the location of each person, to
the 
cube and office level

- someone I was discussing this issue with said to me that the above was
only 
possible under very old laws, allowing such, and that the new laws
require 
911 calls to be sent directly to the 911 services, and that the location
will 
have to be passed on based on the information from a database my
customer 
will have to deliver (and maintain?!?) in coordination with the 911
folks, 
such that each phone will be identified in a specifc area of the
building, 
based on participation in a switch-port connection. To me this sounds 
extreme, because one of the advnatages VoIP has been bringin to the
table 
was ... well ... mobility of phones (no matter where I plug them, they 
register) - so how the heck are we going to be able to continuously
update 
the switch-port info?!?

Any pointers will be highly appreciated - to narrow the scope I would be

mostly interested in USA - Illinois, but of course other states'
deployment 
experience will also be valuable.

If you feel the above is totally off-topic, please accept my apologies,
and - 
if anythiung useful to be added - please email me directly.

Thank you,
Stefan
