What Is Callback International callback saves phone costs Convention says that the shortest distance between two points is a straight line. But when it comes to placing international phone calls from a foreign country, it is often cheaper to place a call to another country through the United States than to do so directly. Convention must never have dealt with international calling. It is this strange, but true, reality that accounts for the healthy growth of the international callback industry.
Many foreign countries charge outrageous rates for international calls.
That way, users can avoid the high rates of overseas telephone monopolies and calling cards when placing calls from abroad. International callback works by having a caller place a call to the service bureau from a previously designated phone number. The user then hangs up and waits for a callback from the service. When the call comes through, the user picks up the line and is patched into another U.S.-based phone line. With this open line, the caller then can dial any number desired.
