recommendation for SIP integration

Hi, I am looking for a solution where I can tie a US number to a SIP solution. Has anyone had experience with this and if so can you make some recommendations?

I've used broadvoice before for personal telephony, and they were competent and asterisk-friendly, and seemed to have DIDs in many US LCAs. <http://broadvoice.com>

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.

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 : Direct Inward Dialing service providers

I have used the CallWithUs guys (http://callwithus.com) and they seem to
very reasonable.

They have an emphasis on keeping things simple, and are happy to chat with
you on a technical level if needed.

Does anyone have any opinion on bandwidth.com as a SIP trunk provider by any
chance?
