This many not end up being a webapp question but right now it seems to me that the answer will most likely me a webapp of some sort.
There are a number of VOIP/SIP/Fax services that I'd like to try out but they don't have any local NH (603) numbers. Most of them do allow porting of numbers. Where can I buy a phone number that I can have ported in? I'm looking for just the phone number, not the voice service to go with it (most VOIP providers don't actually sell you the number anyway, they just lease it to you so you can't port it out).
