Just to throw another name into the arena http://voicepulse.com/ 

Pros: 
SIP and IAX termination
Many US NPP/NXX exchanges and 800 numbers
Config examples for many PBXs
POPs on both coasts
Good knowledgeable customer support

Cons:
Not all NPP/NXX offer LNP (Local Number Portability)
Credit card verification process is annoying, but I understand why

We have used them for several customers as well as our own SIP termination.

Disclaimer: I am not affiliated with them in anyway, just a satisfied
customer.
