“Press 1 for sales, press 2 for support…” Interactive voice response (IVR) menus have routed business calls for decades. An AI receptionist does something different: it holds a conversation. Here is how they compare.
How each one works
IVR plays recorded options and waits for a keypress (or a single spoken word). Each choice sends the caller to a queue, a voicemail box or another menu. It routes calls; it rarely resolves them.
An AI receptionist answers with a natural voice, understands what the caller says in their own words, and acts on it: answering a question from your documents, booking an appointment, taking a detailed message or sending details to your CRM.
Side by side
| IVR menu | AI receptionist | |
|---|---|---|
| How callers interact | Keypad options in a fixed order | Natural conversation |
| Resolves the call | Rarely — mostly routes it | Often — answers, books or captures details |
| After hours | Usually voicemail | Full service, 24/7 |
| Handles unexpected questions | No | Yes, from your knowledge base |
| Setup | Record prompts, design the tree | Write instructions, upload documents |
| Changes | Re-record and re-map | Edit text and save |
| Data captured | Menu choice | Name, reason, details, transcript and summary |
Where IVR still makes sense
A simple menu can be the right choice when:
- You only need to split calls between two or three teams who are always staffed
- Regulations require a fixed, scripted message before routing
- Call volume is so high that routing alone saves real time, and agents handle everything else
Where an AI receptionist wins
- Small teams with no one free to pick up a routed call
- After-hours and overflow cover, where an IVR just leads to voicemail
- Repetitive questions that could be answered on the spot
- Bookings and lead capture, where the goal is to finish the task on the first call
Can you use both?
Yes. Some businesses keep a short menu — “press 1 for emergencies” — and send everything else to an AI receptionist. Others replace the menu entirely and let the AI decide what the caller needs. Starting with after-hours calls is a low-risk way to compare.
The cost question
IVR is often bundled with a phone system, so it can look free. But every call that ends in voicemail or a hang-up has a cost. An AI receptionist is priced per minute — with Narvin, a monthly plan from £0 plus usage, typically £0.42 per minute. See how much an AI receptionist costs in the UK.
