The reverse is also true.
You can get a VoIP providers box from South America and ship it to the US.
The South American number stays with the box. A CU student at Columbia U.
actually showed me how he calls his parents (to ask for more money, of
course ;-) using the box in his dorm room.
The VoIP security issues remain the same. I agree with Rafeeq, there are
more legal/tariff issues here.
