IVR (interactive voice response)
IVR, or interactive voice response, is a phone system that greets callers with recorded prompts and routes them based on keypad presses or short spoken answers.
IVR is the "press 1 for sales, press 2 for support" system. It answers calls automatically, plays recorded menus, and sends callers to a department, a queue, voicemail or a simple self-service option such as hearing your opening hours.
How it works
An IVR follows a fixed menu tree. Callers respond with keypad tones or, in newer systems, a few recognized words such as "billing" or "appointments". Each answer leads to the next branch. Some IVRs also connect to databases so callers can check an account balance or order status without a person.
Strengths and limits
IVR is predictable and handles high call volumes at a low cost per call. It works well when callers' needs fall into a few clear categories.
Its limits come from the fixed menu. Callers whose need does not match an option get stuck, press 0 or hang up. Deep menus are slow. And an IVR routes calls rather than resolving them, so a person or voicemail is still waiting at the end of most branches.
IVR vs AI voice agents
An AI voice agent replaces the menu with conversation. The caller says what they need in their own words, and the agent can answer, book or transfer. Some vendors call this conversational IVR. The difference that matters is whether the system can resolve the request or only route it.
How it relates to Worcia
Concierge, Worcia's AI receptionist, can replace an IVR or sit in front of it. See AI receptionist vs answering service vs hiring.
