IVR systems can be used to control almost any function where the interface can be broken down into a series of simple menu choices. Interactive Voice Response (IVR) systems allow callers to get access to information without human intervention. Thus callers hear a pleasant and cheerful voice 24-hours a day, 7 days a year without any attendant human fatigue. IVR is typically used to service high call volumes, reduce cost and improve the customer experience.
