By the way.....local calling areas don't usually change. Only when they
do a rate center consolidation or break one apart which is quite rare.
Once an NXX is assigned to a rate center, the rate center the NXX is
assigned to also doesn't change. So once you have the rate centers
documented for each local calling area, you really only need to add the
new NXXs assigned to each rate center. Just saying this in case someone
wants to create their own resource.

I believe CCMI sells a product that offers local calling area

If you're on a strict budget or just want to do it yourself, I can
tell you how I've done it on a manual basis in the past. You just have
to marry the local calling area for each rate center from (NECA 4
tariff) with the NXXs associated with each rate center from Local
Calling Guide. NECA 4 is a free public resource that documents which
rate centers are in the local or extended calling area of each rate
center. Local Calling Guide is a free resource that lists all the NXXs
associated with each rate center. Local Calling Guide allows you to do
XML queries, but I'm not sure if there are downloads you can get from
NECA 4. If there are I'm sure you'd have to pay for it.

Does anyone know of any commercial products that can determine if a
call is local?
The product would look at what is defined in the Tariff documents, not
just make the decision based on coordinates/distance between callers.
I am aware of iConnectiv's solution.
Thanks
