Assuming I only operate in one municipality (I do), and assuming I made some sort of connection to the emergency services center in this area, via SIP or a T1 or whatever, does asterisk have a way for me to send the E911 address data?

In fact, they won't do anything like PRI; for the most part, T1s to PSAPs are some type of E&M / FGB / FGD. I am also not sure that you can actually get an access circuit to a PSAP. It may be that the only way to reach one is through 911 TCICs in an SS7 interconnection IMT. Of course, all these E911 companies have to be able to dump calls into PSAPs somehow, but they probably ride the services of some nationwide CLEC in order to do it.> does asterisk have a way for me to send the E911 address data?Asterisk does not have an ALI interface as far as I know. But it is possible to patch the call through various appliances that do. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (706) 338-8599

But I have a slighlty different approach. I use a GSM gateway to provide what are effectively "cellular trunks" that provide 911 (and 411 for that matter) through a cellular carrier. It seems an inexpensive way to ensure 911 service in what is otherwise a 100% VOIP situation.

Please elaborate. Do you fake a cellphone, or do you forward through a cellphone. How do you register each phone number?

>Yes, if you have signed waivers, you may operate without fear of FCC. Just be sure to have physical paper in a file somewhere for each client in the event of an audit. And, this will also satisfy you legal advisors to avoid liability in lawsuit by a consumer towards you for any crazy reason if they think that you provided inadequate E911 service and failed to advise the consumer regards proper use and expectations..>But if you do get those waivers, it is compliant in principle, on that >basis, right? > >-- >Alex Balashov >Evariste Systems >Web : http://www.evaristesys.com/ >Tel : (+1) (678) 954-0670 >Direct : (+1) (678) 954-0671 >Mobile : (+1) (706) 338-8599 > >_______________________________________________ >-- Bandwidth and Colocation Provided by http://www.api-digital.com -- > >asterisk-users mailing list >To UNSUBSCRIBE or update options visit: > http://lists.digium.com/mailman/listinfo/asterisk-users
