We have a need to obtain local numbers throughout the U.S. and worldwide terminated at our US headquarters. It looks like this service is only available when using Voice over IP due to regulations on the PSTN.
Can anyone recommend VoIP aggregator or wholesale services which might provide this?
We would probably need 1000 to 10,000 numbers and be handling about 500,000 minutes a month (i.e. please don't recommend Skype).
