Interactive voice response is a phone system that gathers caller input and routes or serves calls through keypad entries, menus, or speech.

Why Interactive voice response matters

IVR provides predictable routing and self-service, but rigid menu trees can create friction when a caller's request does not match the available options.

How it works in practice

Modern deployments may combine traditional IVR controls with natural-language routing or AI agents that can understand the request and continue to complete the task.
