How to Run a Voice AI Discovery Call (Script + Framework)
A voice AI discovery call has three phases and should take 15 minutes: two minutes understanding the prospect's business, five minutes running a live demo of a bespoke agent you built before the call, and eight minutes presenting pricing, handling objections, and closing. Agencies that follow this structure close at 2x to 3x the rate of agencies that wing it, because every minute of the call builds toward one outcome: the prospect hearing their own business answered by AI and doing the math on what missed calls cost them.
This article provides the exact script, the five qualifying questions you need answered before you quote a price, and the red flags that tell you to walk away. If you have been booking calls but losing deals, the problem is almost certainly structural, not personal.
Phase 1 (Minutes 1 to 2): Understand Their Business
The first two minutes are not rapport building. They are data collection. You need three numbers from the prospect before anything else: how many calls they get per day, what happens when they miss one, and what their average job or appointment is worth. Without these, you cannot run the missed call math later, and without the math, you have no close.
Open the call with something like: "Thanks for booking this, I know you're busy. I want to make sure this is actually a fit for your business before I show you anything. Can I ask you three quick questions?"
The Three Opening Questions
"How many calls does your business get per day?" Most owners underestimate this. If they say "a few," press: "Would you say closer to 5 or closer to 15?" You need a number, not a feeling.
"What happens right now when you miss a call?" The honest answer is almost always "voicemail" or "nothing." That is the pain point. According to a Forbes report, 80% of callers who reach voicemail hang up and call someone else.
"What's your average job or appointment worth?" For a plumber, it might be $350. For a roofer, $8,000. For a dentist, $3,000 in lifetime patient value. This number is the foundation of every ROI calculation you will use for the rest of the call.
Write these numbers down visibly (or repeat them back) so the prospect knows you are paying attention. You will use them in Phase 3.
Phase 2 (Minutes 3 to 7): The Live Demo
The live demo is the single highest-impact moment of the call. Before the call, build a bespoke voice AI agent for their specific business using your white-label platform. This takes about five minutes on your end: paste their website URL, let the platform scrape their site and reviews, and the agent goes live with their business name, services, and hours already loaded. The prospect never sees this setup process.
On the call, frame it like this: "I went ahead and built a custom AI receptionist for your business. Let me show you what it sounds like." Then call the agent live. Let the prospect listen.
Demo Rules
You run the demo. They listen. Do not hand over control. Do not let them call the agent themselves. Do not give them the phone number to "play with later." A prototype is not a finished product, and prospects who test edge cases on an unrefined agent will find flaws and judge the entire concept by them. You control the narrative. You choose which questions to ask. You show the agent at its best.
Ask it questions the prospect's actual callers would ask. If it is a plumbing business, ask about emergency drain service at 9 PM. If it is a dental office, ask about new patient appointments and insurance. Make it feel real, because it is real.
Keep it to two or three calls. More than that and you lose momentum. The demo should take three to five minutes, not fifteen.
The Closing Line After the Demo
"This is what it sounds like out of the box, and we haven't even connected it to your calendar, your CRM, or trained it on your specific services yet. Once we do that, it becomes your best employee. It never calls in sick, never has a bad day, and answers every call within two rings."
This line works because it reframes the demo as a starting point, not a ceiling. Whatever impressed them about the prototype, the finished product will be better. For more on structuring demos that close, see Voice Agent Sales Demo Best Practices.
Phase 3 (Minutes 8 to 15): Pricing, Objections, and Close
Phase 3 is where most agencies lose deals, not because their price is wrong, but because they present it without context. Before you say a number, do the missed call math live on the call using the data the prospect gave you in Phase 1.
The Missed Call Math (Do This Live)
Take the numbers they gave you and multiply:
"You said you miss about 8 calls a week. Your average job is $350. Even if only 30% of those would have converted, that is $350 times 2.4 jobs per week, times 52 weeks. That is $43,680 a year in revenue walking out the door. I am charging you $400 a month, which is $4,800 a year, to catch those calls. That is a 9x return."
Do the math out loud. Let them hear it. The price you quote after this calculation feels small by comparison. For the full breakdown of industry-specific missed call calculations and scripts, see The Missed Call Math.
Present One Number
Do not present tiers. Do not break out per-minute costs. Do not show a Bronze/Silver/Gold pricing table. SMBs want one monthly number that covers everything they need. A confused mind says no.
"Based on what you need, this is $450 a month. That covers 24/7 answering, calendar booking, and SMS confirmations. Month-to-month, cancel anytime, 28-day money-back guarantee." As of June 2026, most agencies price voice AI answering between $300 and $600 per month depending on the vertical and call volume.
One number. Clean deliverables. If you need guidance on setting that number for different industries, How to Price AI Voice Agents covers the one-number rule in detail.
Handle Objections by Resistance Level
Not every prospect objects the same way, and not every objection requires the same response. Match your response to the resistance level:
Resistance Level | What They Say | What to Do |
Level 1: Ready to buy | "That sounds great, let's do it" | Close it. No discount needed. |
Level 2: Price concern | "I like it but it's a bit high" | Offer 10 to 15% for committing today, or remove an add-on to bring price down |
Level 3: Phone number fear | "I don't want to change my number" | Explain call forwarding: their number stays, AI only catches missed calls |
Level 4: Trust gap | "I'm not sure it'll work" | Offer a 28-day money-back guarantee or pay-per-result trial |
Level 5: Stalling | "I need to think about it" | Ask what specifically they are unsure about and address it now |

The 5 Qualifying Questions to Ask Before You Quote a Price
Five questions separate a qualified prospect from a time-waster. Ask all five before Phase 3. If you cannot get clear answers to at least four of them, the prospect is not ready to buy.
"How many calls does your business get per day?" This determines call volume and whether an AI agent makes financial sense. Below three calls per day, the ROI math gets weak.
"What happens when you miss a call right now?" If the answer is "my office manager gets it" or "we have an answering service," you are displacing a human, which is a harder sell than replacing voicemail. Adjust your pitch accordingly.
"What is your average job or appointment worth?" This is the multiplier for missed call math. Higher values make the ROI undeniable. Lower values (under $100) mean you need higher call volume to justify the price.
"Have you tried anything else to solve this problem?" If they have tried and failed with answering services, voicemail systems, or hiring staff, they already know the problem is real. You are presenting a better solution, not educating them on the problem. If they have never tried anything, you may need to spend more time building urgency.
"If this worked as shown, when would you want to start?" This separates buyers from browsers. "Immediately" or "this week" means they are ready. "Maybe next quarter" or "I'll think about it" means they are either not in pain or not the decision-maker.
Red Flags: When to Walk Away
Not every prospect is a fit. Spending 30 minutes on a call with someone who will never buy is 30 minutes you could have spent closing a real deal. Watch for these signals:
Low call volume (fewer than 3 calls per day). The math does not work. If they get 2 calls a day and miss one, the annual cost of missed calls is too small to justify a $300 to $500 monthly fee. These businesses need more marketing before they need an AI agent.
No budget and no urgency. If they say "I need to check with my partner" and cannot give you a timeline, they are not the decision-maker. Ask: "Is there someone else who should be on this call?" If the answer is yes, reschedule with that person present.
"Just curious" energy. Some people book discovery calls because they saw an ad and thought it was interesting. They have no active problem, no missed calls, and no intention of spending money. The giveaway is vague answers to your qualifying questions and zero emotional reaction to the missed call math. Thank them for their time and move on.
They want to build it themselves. If the prospect is technically savvy and starts asking about APIs, which LLM you use, or whether they can self-host, they are not your customer. They want developer infrastructure, not a done-for-you service. This is fine. Point them in the right direction and protect your time.
They are already happy with their current solution. If their answering service or receptionist is working well and they are just price-shopping, you are fighting an uphill battle. The best prospects are the ones whose current system is failing them.
Putting the Full Script Together
Here is the complete 15-minute structure in sequence, with approximate timing for each section:
Minutes 0 to 2 (Qualify): "Thanks for booking this. I want to make sure this is actually a fit before I show you anything. Quick three questions: How many calls does your business get per day? What happens right now when you miss one? And what's your average job worth?"
Minutes 2 to 3 (Transition to demo): "Based on what you've told me, this is exactly the kind of business where this works best. I actually went ahead and built a custom AI receptionist for [business name]. Let me show you what it sounds like."
Minutes 3 to 7 (Live demo): Call the bespoke agent two to three times. Ask realistic questions. Let the prospect listen. After the last call: "This is what it sounds like out of the box, and we haven't even connected it to your calendar or trained it on your specific services yet."
Minutes 7 to 10 (Missed call math): "You said you miss about [X] calls a week. At $[Y] per job and a 30% conversion rate, that's $[Z] per year in lost revenue. This costs $[price] a month, which is $[annual] per year. That's a [multiplier]x return."
Minutes 10 to 12 (Pricing and terms): "Based on what you need, this is $[single number] a month. That covers 24/7 answering, calendar booking, and SMS follow-up. Month-to-month, cancel anytime, 28-day money-back guarantee."
Minutes 12 to 15 (Close or handle objections): If yes: "I can have this live and answering your phones by tomorrow. Want to get started?" If objection: match to resistance level and respond accordingly.
Frequently Asked Questions
How long should a voice AI discovery call take?
Fifteen minutes is the target. Two minutes qualifying, five minutes demoing, eight minutes on pricing and closing. Calls that run longer than 20 minutes usually mean you are over-explaining or the prospect is not qualified. If you hit the 15-minute mark and have not quoted a price, something went wrong in Phase 1 or Phase 2.
Should I build a custom demo agent for every prospect?
Yes. It takes about five minutes to paste their website URL and let the platform generate a trained agent from their site and reviews. A bespoke demo that says their business name and knows their services closes at a dramatically higher rate than a generic "here's what AI sounds like" recording.
What if the prospect asks what platform I use?
You built this. You designed it. You support it. That is the entire point of white-labeling. The prospect sees your brand, your domain, and your dashboard. They do not need to know or care about the underlying platform. If pressed on technical architecture, say: "We built this on a native voice AI platform that we own and operate. It's not stitched together from five different services, which is why the reliability is where it is."
What close rate should I expect from discovery calls?
Agencies following this three-phase structure typically close 25% to 40% of qualified prospects. If your close rate is below 15%, check three things: are your demo agents properly built before the call, are you running the missed call math live, and are you presenting one number instead of tiers. If your close rate is above 50%, your price is probably too low.
What if the prospect says they need to think about it?
Ask what specifically they are unsure about and address it in the moment. "Is it the money, the technology, or whether it'll work for your type of business?" Most "I need to think about it" responses are fear, not logic. If they genuinely need time, follow up within 48 hours. Prospects who "think about it" for more than a week have mentally moved on.
Honest caveat: This framework works for prospects who have a real missed-call problem and enough call volume to justify the investment. It will not save a deal where the prospect has no budget, no urgency, or no authority to make a decision. Qualifying hard in Phase 1 is how you avoid wasting time on calls that were never going to close.
