It's a bit pricey, but the LERG by Telecordia is the best implementation of rate center homing. It pretty much has everything you need to use in a carrier-class enviroment. However, unless you have CLEC status you are tied into the local ILEC's rate centers. http://www.bellatlantic.net/cgi-bin/npa-nxx/ Show's look exchanges for the Bell Atlantic area... I'm sure other RBOC's have these as well.

You might try your own state Public Utility Commission - at least in Ohio the local calling area is a regulated function. Mark Radabaugh VP, Amplex (419)833-3635 mark@amplex.net

i don't see that this is nanog material, unless we want to use it as a springboard to begin complaining about a certain incumbent carrier...

however, the answers are easy:

*your local phone book should have pages in the front which should list local calling areas, usually with a table of exchanges.

*call your local operator by dialing zero, and ask them if, with your calling plan, you can call NXX-1 from NXX-2 toll-free. if s/he says s/he can't tell you that information, ask to talk to their supervisor, because, as the entity billing you for such calls, they should be able to tell you what their billing structure is. (this is the most reliable method.)

if anyone knows of a centralized listing, i'd love to see it. this is something that i deal with everyday, and it can be messy. generally we get a table of "this NXX can be dialed toll free from these NXXs" from whomever is providing our virtual NXXs. however, those lists have proved incorrect in the past, and we INSIST that our phone staff tell our customer to check their access number using the above methods.
