AI Receptionist Prompt: 12 Prompts to Build and Test One

An AI receptionist prompt is the system prompt that tells a phone or chat agent who it is, which business facts it may share, how to book, and when to hand a caller to a person. The 12 prompts below help you write that system prompt from your real facts and then test it before customers hear it. Use only facts you can stand behind, because the agent will repeat them word for word.

Have the agent say it is an AI at the start of every call, follow your state's call recording consent rules, get TCPA consent before any outbound AI-voice calls or texts, and in healthcare use only a HIPAA-compliant platform under a business associate agreement.

Write the core system prompt

1. Role and scope

Write the role section for an AI receptionist at [business name], a [business type]. List what it handles (questions, booking, routing) and what it never does (quotes, diagnoses, promises). Write it in second person.

2. Greeting that discloses AI

Write three short greeting options for [phone or chat] at [business name] that say the caller is talking to an AI assistant and ask how to help. Keep each under 20 words.

3. Fact sheet from my notes

Turn these notes [paste hours, services, fixed fees, service area] into a fact sheet the receptionist may quote. Mark anything that needs a person, and write the exact reply for questions not on the sheet.

Booking and routing

4. Booking flow

Write a step-by-step booking flow using [calendar tool], [slot length], and [lead time]. Collect [fields]. Include a read-back of the date, time, and address, and what to say when no slot fits.

5. Human handoff rules

Write handoff triggers and a transfer script for [person or team] at [number or queue], plus the message template sent when nobody answers.

6. After-hours mode

Rewrite the receptionist's behavior for calls outside [hours]: what it still does, what it stops doing, and the callback promise for urgent cases only.

Safety and tough calls

7. Urgent and emergency rules

For a [business type], list urgent cases [paste]. For each, write what the agent says first. Any life-safety case, such as a gas smell, fire, or medical emergency, must tell the caller to call 911 or the utility before anything else.

8. Angry caller script

Write how the receptionist responds to an upset caller about [common complaint]: acknowledge, do not argue or promise refunds, and offer a person within two turns.

9. Privacy guardrails

Add rules so the receptionist never collects card numbers, passwords, or [sensitive data for this business] by voice or chat, and explains how the customer can share them safely instead.

Test before launch

10. Scripted test calls

Write eight test conversations for this system prompt [paste]: a price not on the sheet, a booking outside hours, an emergency, an angry caller, a wrong number, a request for a human, a caller who will not give an address, and a question about whether it is an AI.

11. Transcript review

Review this call transcript [paste] against the system prompt [paste]. List every place the agent guessed, broke a rule, or asked two questions at once, and suggest the smallest prompt fix.

12. Voice readability pass

Rewrite these receptionist replies [paste] for a voice agent: shorter sentences, no lists read aloud, numbers read digit by digit, and one question per turn.

Write the whole receptionist prompt at once

The flagship AI Receptionist Prompt: Calls, Booking, and Handoff Rules takes your business facts, hours, services, booking rules, urgent cases, handoff path, voice, and channel. It returns the role, greeting, fact sheet, booking flow, safety rules, handoff script, after-hours mode, voice rules, and six test calls. Its example covers a plumbing company, including a gas smell script that sends the caller outside to call for help first.

Tips for a receptionist people trust

Keep the fact sheet short and current, since the agent should say "I don't have that" rather than guess. Make it easy to reach a person, and say up front that the caller is talking to an AI. Check your local rules on call recording and disclosure, and re-run your test calls after every change to prices, hours, or staff.
