IVR, or Interactive Voice Response, is a technology that allows callers to interact with a computerized system through the use of voice or touch-tone commands. This system is commonly used in call centers and other telephone-based services to efficiently route and handle incoming calls. IVR systems can provide a range of services, such as automated customer service, call routing, and data collection, all without the need for a live operator. With its ability to streamline and automate call processes, IVR has become an essential tool for businesses looking to improve customer experience and increase efficiency.
