How to Make a Callback Call -- Easy & simple calling procedure (Click to see a graphic dialing instruction).


1. After you sign up, we assign you a special unlisted U.S. phone number that you will call. This number is your unique Access Number (also called DID number). You dial this DID, wait one ring and hang up. Since you hang up BEFORE a connecting answer, there is no charge for the call from your national or local phone company.

2. Our system has been signaled that you called, our computer will immediately call you back and give you a U.S. dial tone. Upon receiving this callback, you can then proceed to make your call as follows:


For calls to U.S., Canada and the Caribbean, you must dial

1 + Area Code + Number.
You may press (#) after dialing your number to speed up your call processing;

For calls to any other country in the world, you need to dial

011 + Country Code + City Code + Number.
You may press (#) after dialing your number to speed up your call processing;
To speed-dial, you must dial the two digit speed dial number, enter 99 to redial the previous number, press (**) to make another call, or press (##) to exit the system.
