We've encounters this problem a few times both when dealing with carriers and internally. When you start to mix VoIP and Traditional Telecom Carriers it can get hairy with all the different formats they want calls in, especially when you start dealing with international carriers. We ended up standardizing our internal voice network on a CC+CityCode format for all calls and then building specific translations for each carrier on their inbound and outbound trunks.

For the good of the order...
We just worked through an issue in which 10 digit domestic calls were being routed (correctly) as domestic but rated and billed (incorrectly) as international.
503-nxx-xxxx were rated for El Salvador, etc.
We caught it pretty early, and the carrier fixed it for us. Still, it was a pretty interesting problem to work through, and something to add to your list of "things that can go wrong".
An interesting issue. We almost had something similar happen internally because one of our carriers (soon to be ex-carrier) only sends and accepts ten digits on US calls, and country code without the + on international. The way our routing and billing is set up we expect to use the country code on all calls. They think we're strange to expect it that way.
Something to add to the list of questions for potential carriers.
