AI voice receptionist: talk to the booking brain

You're a caller at Maple Street Salon, a made-up business. Press Talk and say what you want, type it, or pick a line. Every booking, answer, cancel and hand-off is decided by the real engine from our n8n AI receptionist kit, running right here in your browser. Watch the Google Sheet tabs fill in, and see the call record and hand-off note the team would get.

What's real and what isn't on this page

RealThe decision logic: availability, opening hours, buffers, minimum notice, double-booking refusal, FAQ matching, "only the number that booked can cancel", and staffed-hours escalation. It is the code from the kit's 01 Tool Router workflow (v1.0.4), copied unchanged, getting the same request format Vapi sends.
ScriptedThe conversation. In a real deployment an AI voice model (Vapi or Retell) understands the caller and decides which tool to call. Here, what you say or type is matched to a tool by simple keyword rules written for this demo, and the receptionist's wording is a fixed template built from the engine's answer.
Your browser's voiceTalk uses your browser's built-in speech recognition and "Read replies aloud" uses its built-in speech synthesis. No AI model and no paid API is called. In Chrome, speech recognition may be processed by the browser maker's servers; nothing is sent to us. If your browser has no speech recognition, type instead.
Rule-basedThe call record and hand-off note are built from the call's tool results with fixed rules. In the kit, workflow 02 logs each call with the voice platform's own summary.
SimulatedThe "Google Sheet" and alerts are tables in your browser. Nothing is saved, sent or called. Reload to reset.
SampleThe salon, its services, prices, FAQ, phone numbers (555 numbers) and the people (Ann Lee, Sam Demo) are fictional.
This demo has never answered a real phone call. We haven't run a live voice call yet because that needs a paid voice-platform account. No client has used it yet, so there are no client results to show.

The call

Read replies aloudTry: "Book a haircut Saturday morning", "Do you take Apple Pay?", "I need the owner, it's urgent".

The salon's Google Sheet in your browser

In the kit these are tabs of the owner's own Google Sheet. "Alerts" are what would go to the owner by Slack and email.

Last webhook round trip

Request in Vapi's tool-calls format, and the engine's reply.

Call record and hand-off built from the tool results

What the owner sees after each call: outcome, tools used, what the caller said, and a hand-off note when a person needs to follow up (urgent requests, messages, questions the FAQ can't answer). Switching caller starts a new call.

Things to try

Book, then book the same slot again. A platform retrying the tool call gets the same booking back ("already saved"), not a duplicate row.

Ask for Ann's 2 PM slot. It's refused and the nearest free times are offered. The 10-minute buffer around her booking is respected too.

Switch to the other caller and cancel. It refuses: only the number that made a booking can cancel it by phone.

Ask something not in the FAQ. It won't make up an answer, and the question is logged to FAQ_Gaps.

Colour on the blocked morning. That morning is blocked for staff training, so it moves to the next free slot that fits a 90-minute service.

Ask for the owner. During staffed hours (Mon–Fri 9–5 New York) it transfers. Outside them it takes an urgent message and alerts the owner.

How the real kit is wired from the real workflow files

Five n8n workflows. These diagrams are drawn straight from the shipped .json files (node names, types and connections). Nothing is added for show.

Diagram of the AI Front Desk n8n workflow

Wide diagram: scroll sideways on a phone.

1. Call comes in. The caller talks to an AI voice assistant on Vapi or Retell, on the owner's account and phone number.

2. Tools hit n8n. The assistant calls 6 tools (check availability, book, cancel, answer FAQ, take message, escalate). Each one is a webhook to workflow 01, which reads and writes the owner's Google Sheet.

3. After the call. Workflow 02 logs the call with outcome and summary, and flags missed opportunities. 03 emails a daily report, 04 mirrors bookings to Google Calendar, and 05 alerts on errors.

Test results from the kit's test report

38 / 38unit tests: booking engine, parsing, FAQ, escalation, reports, workflow checks

26 / 26end-to-end tests on a real n8n 2.44.6 with live webhooks (Google, Slack and email replaced by a local mock)

12 / 12scheduled-workflow tests: daily report, calendar mirror, error alerts, Google Calendar outage and recovery

Also: the Vapi setup script passed 10/10 tests against a fake Vapi API. The voice layer on this page is checked by our page tests with a simulated microphone; see the case study.

Live check on n8n Cloud with a real Google Sheet and Google Calendar (27 Oct 2026): all 7 tool paths returned the expected results, at about 1.7 to 5.7 seconds per tool call including Google Sheets. A booking created a real Calendar event, and cancelling it deleted the event.

Not tested yet: a real phone call or AI chat (voice quality, speech recognition, how well the AI model follows the prompt). That needs a paid Vapi or Retell account. The kit includes a 10-call go-live checklist for that step.

AI Front Desk kit for n8n

The 5 workflows, a 7-tab Google Sheet template, Vapi and Retell tool definitions, a setup script, a call simulator, setup guide and test suites. Runs on the owner's own n8n, Google and voice-platform accounts. Voice minutes are billed by the voice platform.
