1. Q-CallBack-DID - Call Back triggered by dialing unique telephone number
When you want to make an international long distance call, you will first dial a unique telephone number assigned to you by EcoCarrier to reach EcoCarrier's Call Back IVR Server/Switch to trigger a call back call to a pre-determined telephone number.
When you dial the unique telephone number, you will hear a busy tone and you should hang up the telephone right away. EcoCarrier's Call Back IVR Server/Switch reads the unique telephone number dialed (by you) and uses it to identify you and then call you back at the pre-determined telephone number (this is the First Leg of the Call Back Call).
When you answer the incoming call from the Call Back IVR Server/Switch, you will hear a voice message Enter your destination number played by the Call Back IVR Server/Switch.
The Call Back IVR Server/Switch takes note of the Destination Number (DN) dialed by you and then dials the DN (this is the Second Leg of the Call Back Call) and then bridges the First Leg call and the Second Leg call together for a telephone conversation to take place.
2. Q-CallBack-SMS - Call Back triggered by sending SMS

The IVR Server/Switch first calls the Call Back Number (the First Leg of a Call Back Call), and when the Call Back side answers, it plays a voice message like You have 5 dollars and 0 cents. Thank you. Please hold. and then it proceeds to call the Destination Number (the Second Leg of a Call Back Call).
The Call Back IVR Server/Switch then bridges the First Leg call and the Second Leg call together for a telephone conversation to take place.
3. Q-CallBack-Web - Call Back triggered by sending request through a webpage
