IVR
IVR (Interactive Voice Response) is a technology that allows automated phone systems to interact with callers through voice or keypad inputs, typically using pre-recorded messages and menus. It enables businesses to handle high volumes of calls efficiently by routing callers to appropriate departments, providing information, or completing transactions without human intervention. Common applications include customer service hotlines, banking systems, and appointment scheduling.
Developers should learn IVR when building or maintaining telephony systems for customer support, automated services, or call centers, as it reduces operational costs and improves accessibility. It is particularly useful in industries like finance, healthcare, and retail for handling routine inquiries, payments, or bookings, allowing human agents to focus on complex issues. Knowledge of IVR is also valuable for integrating voice-based interfaces with web or mobile applications.
