| | The callback, also called ”phone-to-phone”, is a procedure of phone callback allowing to phone without needing to use a headset-microphone or a computer.
During the call of a callback, the voip server calls you back on your mobile or fixed line (incoming-call) and dials then the number of your correspondent before the beginning of your conversation.
The call will not be charged by your traditional operator because it is an incoming call on your line. But it will be charged to the operator voip who called you back.
The rates of a voip operator allowing the callback are quite often sharply cheaper that those of your traditional operator, this is the reason of the success of this way of calling. | |
