i subscribed my home phone to primus. It has two way to call back. one is 7 cents paer minute, one is 10 cents. THe 7 cent quality is not very good, but the 10 cents one is very good, and it is directly calling by dail 011-86-dxfdxfdfdgf.
So far i am very happy with it. And the company is a big one, so u dont hav to worry anything.
