Interactive voice response (IVR)

Interactive voice response (IVR) is the system that greets the caller with a recorded message and offers a tree of choices: "for a quote, press 1; for repairs, press 2." It recognizes keypad tones (DTMF), sometimes voice on recent versions, and routes the call accordingly. It's first-generation phone automation, ubiquitous since the 1990s.

Its reputation is deserved: seven-level labyrinths, no zero option to reach a human, the message repeated three times — badly designed IVR has become the symbol of customer contempt. Used in a small dose (a three-option menu with a quick exit), it helps; stacked, it manufactures exasperated callers who call back from hidden numbers out of spite. The AI voice agent is the next generation: instead of a menu, a conversation; instead of keypresses, a question understood and a useful answer.
