You can check your Qudo CallCard and Qudo SIP and Qudo Callback rates by choosing corresponding menu on the left hand side. Please note that Qudo CallCard and Qudo SIP calling rates are the same.

For Callback the rates are different because they depend from which country you are calling from. The call consists of two call legs: one to the caller and one to the destination. You can make long distance calls virtually from anywhere from any phone. Generally callback works as follows:

1. The caller initiates the call by calling an access number and hanging up.
2. The service provider reads the caller id of the call and calls back the caller at that number.
3. The caller answers the call.
4. The service provider prompts for the destination number.
5. The caller inputs the destination number.
6. The service provider calls the destination number and connects the two calls together.
