Routing intra or inter state

Hello everyone,

 

Here is my problem. We have a client in USA that want to route his calls depending on the state where the caller and the called are.

Here is a "picture" of the idea:

 

For more information. If from-area-code=to-area-code we will route the call through the provider B. If not, we will route the call through the Provider A.

 

My first idea was to use regex on fields "to" and "from" of the local-policy but as I thought it's impossible.

I don't have other ideas, if someone has some ideas to help me in that case it could be really helpfull for me.
