All you have to do is create a free account and obtain an access number. When making a call, dial the access number, let the phone ring once, and hang up. You will receive a call back within seconds to let you know you are now using the callback service line. Dial the international phone number and you will be billed later. The international callback service will log in the amount of time you spend on the call and bill you for those minutes only. If you place a call that is unanswered, you will not be charged.

Another advantage to using an international callback service is that you can make calls using your office line and other landlines, or you can use your mobile device. If you are traveling for business, on vacation, or telecommuting from home for a few days, you will be able to conduct business and be billed for it later.
