they are a broadband phone company. you can pick any area code in the country and you have unlimited national dialing for $40. plugs into your router. you can also add a 800 # for $5 a month and a fax line for $10.
one other cool thing i love is that my voicemails get emailed to me as wav files so i don't have to dial into the system. the web interface allows you to see all of your incoming and outgoing calls and manage your account.
i just got mine and its sweet. they give you a cisco phone adapter with your account. anyways, i think they have international forwarding but you should check...
