12 AI Receptionist Prompt Templates & Greeting Examples You Can Copy (2026)

Stop writing AI receptionist prompts from scratch. Below are 12 production-ready templates across 6 industries, 25+ greeting examples sorted by tone and situation, voice settings recommendations, and edge case scripts you can copy directly into VAPI, Bland AI, Retell, ElevenLabs, or any voice AI platform.

Every template in this guide is actively used by agencies managing real client accounts. They're not theoretical — they're built from thousands of real calls, refined based on transcript reviews, and structured to minimize the mistakes that make AI receptionists sound robotic or unhelpful.

If you want to understand the why behind prompt structure — how voice AI processes instructions, why certain formats work better than others — read our AI Receptionist Prompt Engineering Guide. This page is the what: the actual templates you copy, customize, and deploy.

How to Use These Templates

Each template below follows a consistent format. Every section marked with [brackets] needs to be replaced with your client's specific information. Everything else can be used as-is.

AI Assistant Greeting Response Examples (25+)

The greeting is the single most important line in the entire prompt. Callers decide within 3 seconds whether they trust the voice on the other end. A great greeting is short (under 15 words), identifies the business, and invites the caller to speak. Below are 25+ greeting examples organized by tone, situation, and industry.

Professional Greetings (Law, Medical, Financial)

• “Thank you for calling [Business Name]. How can I assist you today?”
• “[Business Name], good [morning/afternoon]. How may I help you?”
• “You've reached [Business Name]. How can I direct your call?”
• “Thank you for calling the office of [Doctor/Attorney Name]. How can I help?”
• “[Business Name], this is the front desk. What can I do for you?”

Warm & Conversational Greetings (Home Services, Retail, General)

• “Hey there! Thanks for calling [Business Name]. What can I help you with?”
• “Hi, you've reached [Business Name]! How can I help?”
• “Thanks for calling [Business Name]. What's going on?”
• “[Business Name], how can we help you today?”
• “Hey! Thanks for calling. What can we do for you?”

Emergency-First Greetings (Plumbing, HVAC, Electrical, Towing)

• “Thanks for calling [Business Name]. Do you have an emergency, or would you like to schedule a service?”
• “[Business Name] here. Is this an emergency, or can I help you with scheduling?”
• “Thanks for calling [Business Name]. If this is an emergency, say ‘emergency’ and I'll get you help right away. Otherwise, how can I help?”

After-Hours Greetings

• “Thanks for calling [Business Name]. We're currently closed, but I can help you schedule an appointment or answer questions. What do you need?”
• “Hi, you've reached [Business Name] after hours. I can still help with scheduling, pricing questions, or take a message. What works best?”
• “[Business Name] is closed right now, but I'm here to help. Would you like to book an appointment for tomorrow, or do you have a question I can answer?”

Patient / Client Segmentation Greetings (Medical, Dental, Legal)

• “Thank you for calling [Practice Name]. Are you an existing patient, or would you like to schedule your first visit?”
• “[Firm Name], how can I help you? Are you a current client, or is this a new matter?”
• “Thanks for calling [Practice Name]. If this is a medical emergency, please hang up and call 911. Otherwise, how can I help you today?”

Restaurant & Hospitality Greetings

• “Thanks for calling [Restaurant Name]! Are you looking to make a reservation?”
• “Hi, [Restaurant Name]! How can I help — reservation, takeout, or something else?”
• “[Restaurant Name], thanks for calling! Would you like to book a table?”

Real Estate Greetings

• “Hi, thanks for calling [Team Name] Real Estate! Are you interested in a property, or looking to sell?”
• “[Team Name] Real Estate, how can I help you today?”
• “Thanks for calling! Are you looking for information on a specific listing, or would you like to speak with an agent?”

Voice Settings by Industry

The prompt controls what the AI says. Voice settings control how it sounds. Here are the recommended voice configurations by industry, tested across thousands of calls. These settings go into your voice AI platform's configuration panel (not into the prompt text itself).

Platform-Specific Notes

• VAPI: Stability and similarity map to the voice provider settings (ElevenLabs, PlayHT, etc.) configured in your voice settings. Response delay is set in the “Advanced” tab — use 300-500ms.
• Bland AI: Voice speed is set in the pathway configuration. Use “wait for silence” at 5 seconds for most industries, 8 seconds for medical and legal.
• Retell: Response delay and interruption sensitivity are in the agent settings. Set sensitivity to “medium” for most cases — “low” for medical where callers need time to explain symptoms.
• ElevenLabs Conversational AI: Stability and similarity boost are direct settings. Start with 0.5/0.7 and adjust based on test calls.

Edge Case Scripts to Add to Any Template

The templates above handle 90% of calls. The scripts below handle the other 10% — the situations that trip up AI receptionists and frustrate callers. Copy these into the BOUNDARIES or FLOWS section of any template.

When the Caller Doesn't Speak

If no response after greeting, wait 4 seconds then say: 
"Hello? Are you there?" Wait 4 more seconds. If still no response: 
"I can't hear you — please try calling back, or visit our website 
at [URL]. Goodbye."

When the Caller Asks “Am I Talking to a Robot?”

If asked whether you are AI or a real person, answer honestly: 
"I'm an AI assistant for [Business Name]. I can help with scheduling, 
answer questions about our services, and take messages. How can I 
help you today?"

When the Caller Speaks a Different Language

If the caller speaks Spanish: Switch to Spanish and continue 
the conversation. Greet with: "Gracias por llamar a [Business Name]. 
¿Cómo puedo ayudarle?"

If the caller speaks a language you don't support: "I'm sorry, I'm 
only able to assist in English [and Spanish]. Can I take a message 
and have someone call you back?"

When the Caller is Angry

If the caller is upset:
1. Acknowledge: "I understand that's frustrating, and I'm sorry 
   you're dealing with this."
2. Don't be defensive. Don't explain why something happened.
3. Focus on resolution: "Let me see how I can help fix this."
4. If still upset after 2 attempts: "I want to make sure this gets 
   resolved properly. Let me have [owner/manager] call you back 
   personally. What's the best number and time?"

When It's a Spam / Sales Call

If the caller is trying to sell something or is clearly not a 
customer: "Thank you, but we're not interested. Have a good day." 
End the call politely. Do not provide any business information 
to sales callers.

After-Hours & Holiday Templates

Many businesses want different behavior during and after business hours. Here's how to modify any template for after-hours operation.

After-Hours Additions (Add to Any Template)

## AFTER-HOURS BEHAVIOR
When calls come in outside of [business hours]:

1. Use after-hours greeting: "Thanks for calling [Business Name]. 
   We're currently closed, but I can help you schedule an appointment 
   or answer questions."

2. For appointment requests: Book as normal for next available 
   business day. "I've scheduled you for [time] on [day]. You'll 
   receive a confirmation when the office opens."

3. For emergencies (home services only): "For emergencies outside 
   business hours, [provide emergency protocol — e.g., 'I'm sending 
   an alert to our on-call technician' or 'please call our emergency 
   line at XXX-XXX-XXXX']."

4. For everything else: Take a message. "I'll make sure the team 
   gets this first thing in the morning. They'll call you back by 
   [time]."

Holiday Closure Template

## HOLIDAY GREETING
"Thanks for calling [Business Name]. We're closed today for [holiday]. 
We'll reopen on [date] at [time]. I can take a message or help you 
schedule an appointment for when we're back. What would you prefer?"

How to Customize Templates for Your Client

If you're an agency deploying AI receptionists for multiple clients, here's how to efficiently customize templates at scale.

Pre-Launch Testing Checklist

Before any AI receptionist goes live with real callers, run through this checklist. Every item should pass.

1. Greeting test: Call the number. Does the AI greet with the exact script you wrote? Is the voice and speed correct?
2. New appointment flow: Request an appointment as a new customer. Does the AI collect all required information? Does it confirm details back?
3. Pricing question: Ask “How much does [service] cost?” Does the AI give a range (not an exact number)? Does it offer to schedule?
4. Emergency handling: Describe an emergency. Does the AI respond with urgency and collect the right information?
5. Out-of-scope question: Ask something the AI shouldn't know. Does it gracefully say it doesn't know and offer a callback?
6. Angry caller test: Act frustrated. Does the AI acknowledge your frustration and offer to escalate?
7. Silence test: Don't say anything after the greeting. Does the AI handle it gracefully?
8. Boundary test: Ask the AI to do something it shouldn't (give medical advice, guarantee a price, badmouth a competitor). Does it decline properly?
9. Call duration: Is the AI resolving calls in a reasonable time? Most calls should be under 3 minutes.
10. Transcript review: Read the transcript of each test call. Is the information captured correctly? Any awkward phrasing?

Frequently Asked Questions

What's the best AI voice receptionist prompt format?

The most effective format uses clearly labeled sections: Identity, Personality, Knowledge, Greeting, Conversation Flows, Boundaries, and Escalation. This structure works because voice AI models process segmented instructions more reliably than unstructured paragraphs. For a deep dive into why this structure works, see our prompt engineering guide.

Can I use the same template for multiple clients?

Yes. That's exactly how these templates are designed. The structure, personality, flows, and boundaries stay the same for clients in the same industry. You only customize the bracketed fields: business name, hours, services, pricing, and unique FAQs. Most agencies maintain 4-6 base templates and customize from there.

How do I write AI assistant greeting responses that sound natural?

Keep greetings under 15 words. Start with the business name, not “Thank you so much for calling.” End with an open question that lets the caller state their need. Avoid corporate phrases like “Your call is important to us.” Test by reading the greeting out loud — if it feels stiff when you say it, it'll sound stiff from the AI.

What voice AI platforms do these templates work with?

Every template is platform-agnostic. They work with VAPI, Bland AI, Retell, ElevenLabs Conversational AI, and any platform that uses a text-based system prompt. You may need minor formatting changes depending on how each platform parses sections (some prefer markdown headers, some prefer plain text labels), but the content is universal.

How long should an AI receptionist prompt be?

600-1,200 words for the core prompt. The templates in this guide average around 800 words before you fill in the business-specific details. If your prompt exceeds 1,500 words, the AI starts losing focus. Move detailed FAQs and knowledge into the platform's separate knowledge base rather than stuffing them into the main prompt.

Do I need different prompts for business hours vs. after hours?

Ideally, yes. The main differences are the greeting (mention that you're closed), the scheduling flow (book for next business day), and the emergency handling (different escalation path). See the after-hours template additions above. Most voice AI platforms support time-based prompt switching automatically.

These templates are a starting point — not a finished product. The best AI receptionist agencies test every prompt with real calls, review transcripts weekly, and refine based on actual caller behavior. Start with the template, customize it, test it, and iterate. For the principles behind why this prompt structure works, read the companion AI Receptionist Prompt Engineering Guide.
