911 information for 1 MB

[Wings08]

I am going to order 4 measured bussiness lines for disaster recovery in our new building. Is there a way of providing location information, besides the site address, if there was a 911 called made from that phone. IE. 1st Flr. SWA Emergency Dept.
Carrier will be ATT.

There is if you have/buy a location server. But, that really applies to IP phones since they are more mobile (location-wise/plug and play). For a business provided ATT line that is a POTS/CO Trunk that typically only uses BTN (billing telephone number/address) unless your PSAP uses enhanced 911. We have a 24x7 staffed post (security) that we direct our employees to call but it is always best practice to call 911 and have an additional employee (if available) call security for 911 responders to locate the individual properly. It is nearly impossible for us to locate every employee as we have a warehouse so we would need a location server and setup a grid-based system.
There are always cell phones in a DR situation (which hit the nearest tower). I am not sure if that is sufficient however.
You are supposed to use your local PBX trunks first and then DR to a POTS/COT line - if all that is down about 90% or more of people have cell phones these days. You need to check your local law to be sure of what is acceptable so you don't end up in court down the wrong path. 4 lines seems a bit excessive unless you think you would have 4 people calling 911 at the same time. However, we do have separate lines for fire, burglar, and elavator if that is what you may be referring to. In that case, yes it is recommended to have a carrier-provided line in case the PBX is offline for some reason. That is not to say that the carrier-provided line cannot ever go down either ... our 911 COT was accidentally disconnected because it was not labeled properly.
