I use Flowroute myself (www.flowroute.com) .. you can do single DIDs 
tied to a SIP peer, virtual PRIs, and a number of other things. You can 
even get a free account to test your setup. Here's the list of area 
codes they offer them in : http://www.flowroute.com/services/dids/

I'm just using it for my personal Asterisk setup, so I'm not sure how 
they scale out. They claim to support thousands of simultaneous calls to 
most international destinations.

Here's a link to a bunch of others :
