Which functionality does Avaya's Integrated Voice Response (IVR) provide?

Avaya's Integrated Voice Response (IVR) system primarily provides automated interaction with callers, allowing businesses to manage customer inquiries efficiently. This technology enables callers to navigate through a series of automated prompts and options, typically via voice or keypad input, to receive information or perform tasks without the need for live agents. It streamlines processes such as checking account balances, scheduling appointments, or routing calls to the appropriate department, enhancing customer experience by ensuring quick and accurate responses to their needs.

While other options may represent functions within broader business operations or systems, they do not accurately describe the specific capabilities of an IVR. For example, invoice generation pertains more to billing systems, real-time data analytics focuses on performance measurement and insight gathering, and system security permissions involve access control measures, none of which are core functionalities of an IVR system.
