Interactive voice response (IVR) systems allow callers to interact with a company's phone system using voice prompts and touchtone inputs rather than speaking to a live operator. IVR systems answer calls automatically, use prerecorded menus and options that callers can select by phone keypad, and can answer simple questions in order to free up employees to handle more complex issues. They provide 24/7 automated service to customers who can access simple information quickly from anywhere at any time.
