TARIF is tightly molded around the most popular and widely used technology called Interactive Voice Response System. In telephony, Interactive Voice Response, or IVR, is a computerized system that allows a person, typically a telephone caller, to select an option from a voice menu and otherwise interface with a computer system. Generally the system plays pre-recorded voice prompts to which the person presses a number on a telephone keypad to select the option chosen, or speaks simple answers such as “yes”, “no”, or numbers in answer to the voice prompts.
