If you have access to the internet, you can use any telephone anywhere to make a call and have the call charged at very low VoIP rate. VoIPstudio calls the phone you’re making the call from (see
(1) in the figure above), then makes another call to the person you want to call (see
(2) in the figure above); then connects both together (see
(3) in the figure above). So you will be charged for two calls. But because VoIP prices are so low, even with two calls, this is still a more economical way of making a call than, say, from your mobile. If you are travelling abroad you can avoid roaming charges by using web calls.
