AccuData is one I've used with great success in the past. 

No matter who you use, however, keep in mind that you can keep your costs down by keeping a local cache in a database. Just check the local cache to see if the number matches a record, an if it's not older than your configured TTL, use the record :-)

You have to keep in mind that even with SS7 interconnects with companies like callwithus they may or may not have access to the full national cnam infrastructure

CNAM is hosted by the LEC that owns the DIDs and you have to have an interconnect agreement with them to get to their CNAM...  Simply having an SS7 connection is not enuff
