[cisco-voip] E-911 setup ERL information

Testing in some locales can get you in a lot of trouble or at least a lot of bitching from the PSAP. I've heard in the city of Alameda, CA, they want to charge you hundreds of USD for every test 911 call you make unannounced.

When in doubt, call the public safety office first.

Back to the topic, I would concur that 911 information is handed to the telco and they decide what to do with it. They should have your phone number with its associated location in a giant database. This information is handed off to the PSAP and they decide whether to charge you hundreds of dollars for an unannounced 911 test call.

I've had a case where an office's PRI line terminated in the next county. When we called 911, they didn't have a location registered to the phone number. Weird but it happens.

As far as I know, E911 information is given to the Telco, not the PSAP. The PSAP rarely wants to hear from you. Even testing is getting to be a bit of an issue in metropolitan areas.

You have to get a PSALI type service from your provider. This costs money and allows you to update the records for the DIDs you have purchased. In Canada anyways.

CUCM 7.x with Emergency Responder 7.x.  I have all of
the translations and locations setup working correctly. My problem is with the
local PSAP operator. The place I am setting up is a large campus but the local Telco
did not offer PRI’s or CAMA trunks before this installation. This
customer has enough clout locally to get the Telco to get the equipment so they
can have PRI’s because they wanted to implement E-911 to the police even
though there is no law requiring it yet.  Now when I try to export my
location information the local PSAP administrator does not know what to do with
it. He states that all of that is handled by AT&T at the MSAG. I don’t
know what MSAG is but it sounds like that is where I need to go.  Does
anyone know of a standard way to export the information that AT&T would
accept. I think I have hit a brick wall locally.
