Callback Service

As the name suggests, these services call you and then place your call at cheaper rates. You initiate the call by dialing a "trigger number -a connection to the call-back service's computers. Let the call ring once and then hang up. The computer calls you back from the United States using lower international rates and makes the connection after verifying your account number. Often cheaper than direct-dial calls, but the services may not work at hotels, where staff may not accept the return calls. The service is welcome to those who make lots of international calls.
VoIP works by digitalizing your voice and sending it via the Internet to the person you're calling, who hears it on his PC speakers, or by routing it through regular telephone lines to anyone *s standard phone line. VoIP services generally work best with a broadband or wireless Internet connection and can be used from hotel rooms, Internet cafes or wireless hot spots if you have a notebook computer. Since most calls use the Internet, and connections into and out of the Internet are typically local calls, the rates are astonishing low.
