Every AI receptionist demo runs the same script. Someone shares a screen, a pleasant robot books a haircut for a fictional Tuesday at three, everyone makes an impressed noise, and then the pricing slide shows up. I've sat through enough of these to believe the demo tells you close to nothing. A handful of questions tell you almost everything, and you can ask them in about ten minutes.

You're shopping because the phone gets missed. A 411 Locals study that placed calls to 85 small businesses reported that 62 percent went unanswered, and whatever your own number is, it isn't zero. Voice quality is the easiest thing to stage in a demo and the least useful thing to test. What you need to know is whether the thing hooks into the phone number, the calendar and the customer list you already have, and what it does when it's out of its depth. In that order.

1. "What number does it answer on?"

Ask it exactly like that, then stop talking and let them fill the silence. Some vendors hand you a brand new number and expect you to repaint the van, edit the Google listing, and reach every fridge magnet you've handed out since 2011. Others forward from the line you already have. Then the follow-ups start. Does caller ID still show the caller, or does every call now look like it came from the vendor? What happens to the voicemail box that's already full? How many rings before it picks up, and can you change that yourself at 6am on a Monday? And when you cancel, how long until your number is back under your control?

Rocketship answers calls to the number you already have, through call forwarding, so callers never learn a new one. If you'd rather have a dedicated number, that's a separate line at $5 a month on Launch and Frontier, and it's included on Mission Control. A vendor that can't tell you plainly which of those applies is telling you something.

The second half of the same question: what happens on a call it can't handle? If the reply is "it takes a message and emails you," you've bought voicemail with better grammar. The Numa Small Business Phone Report reports that 85 percent of callers who reach voicemail never call back, which makes a polite message-taker an expensive way to lose the calls you're already losing. You want a live transfer to a person while the caller is still on the line, plus a system that knows your hours, services and prices, so most calls never need transferring at all.

2. "Where does the booking actually end up?"

This is the question that separates a product from a science project. Make them book something during the demo, then make them open the calendar in front of you. Not a summary of the calendar. The calendar.

Then ask whether it checked availability before it promised that slot. A system that cheerfully books Tuesday at three without looking will eventually book two people into Tuesday at three, and I'd take a missed call over that every time. Two customers, one driveway. A missed call is a maybe. Two vans in the same driveway is a story somebody tells at a barbecue.

The most common thing I hear from owners who tried one of these and quit is that they ended up doing the same admin anyway, just at 9pm, off a transcript, with the caller's number typed in by hand. That's the tax you're trying to avoid. The caller's name, number and what they wanted should land somewhere you can pull up next Thursday, not only in an email you'll archive. Rocketship keeps it as one record, so the woman who called about a blocked gutter on Saturday is the same record the AI worker can email or ring back on Monday. Whatever vendor you're looking at, the test is the same: after the call ends, where is the customer?

3. "What's my bill in the month everything goes wrong?"

Nobody quotes you the storm month. They quote you the average month, which you'll never have. So hand them a scenario: a heat wave in week one, a burst-pipe Thursday in week two, the other shop in town closing on the Friday, and your call volume doubled for twenty-one days straight. Ask what the invoice says. Then get these in writing, in the email thread, not on the call:

  • Calls or minutes included, and the exact per-minute rate past that.
  • Whether a transferred call gets billed twice, once by them and once by your carrier.
  • Whether outbound follow-ups come out of the same pool.
  • What "unlimited" means in the terms of service, in the paragraph nobody reads.

A vendor who won't put those four lines in an email is telling you the answer is embarrassing. For what it's worth, here are ours. Launch is $24.99 a month and includes 30 voice minutes. Frontier is $79 a month with 80 voice minutes, and Mission Control is $149 a month with 150. Answering a number you already have is included from Launch, and a dedicated line is an extra $5 a month. The $12 Builder plan is the site builder only and doesn't answer phones, so don't read it as the receptionist price. Every monthly plan starts with a 7-day free trial, card required.

4. "What does it say when it doesn't know?"

Somebody is going to call your business and ask a question nobody ever wrote down. Does that price include hauling the old unit away? Can you come Sunday? Is your tech licensed in Kenton County, because the last guy wasn't. Your AI receptionist will hit that wall inside the first twenty calls, and what it does in the next four seconds tells you more than any demo.

A voice AI has three options when it doesn't know, and all three look identical on a pricing page.

The first is the bluff. A caller asks what full ductwork replacement runs on a 1,900-square-foot ranch. Your price list stops at "system install, from 6,500." Instead of stopping where your facts stop, the AI produces a confident 4,200. Now somebody is holding a recorded call in which your business quoted 4,200 for nine grand of work. You eat the difference or you've the worst conversation of your month.

The second is the stall. "I can definitely help with that! Now, what can I help you with today?" Round and round. Nothing false gets said, which is why owners assume it's the safe failure. The caller hangs up around ninety seconds and dials the next name on the map.

The third is the one you're paying for. "I don't have that in front of me, let me get you to Dave." Or, when Dave is under a house at 8:40 at night: "I can't answer that one and I don't want to guess. I've got you at 859-555-0148, is that the best number? He'll call you before ten tomorrow." That call gave up the question and kept the customer. Most voice AI pitches get that trade backwards, because conceding anything sounds terrible in a sales call.

Language models want to be helpful. Left alone, one will produce something plausible for any question, because plausible text is the whole job. Getting it to stop at the edge of what it knows means fencing it to a specific set of facts: your hours, services, prices, and your rules about deposits, travel fees and Saturday rates. Inside the fence it answers. Outside it says so and moves the caller to a person. People guess too. A summer temp guesses forty times before school starts. An AI answering every call at every hour guesses the same wrong way forever.

When the handoff happens, check what the fallback message contains. A useful one carries:

  • The caller's number, read back and confirmed out loud on the call.
  • What they asked, in their words, not flattened into "customer had a pricing question."
  • What the AI already told them, including anything it committed you to.
  • When they called and what they were trying to book.

The third item is the one everybody skips and the one that bites. If your receptionist told a caller someone would confirm by five, you need to know that promise exists before five o'clock. In Rocketship those details land as a record you can open, in the same place a lead from your website form lands, so it's one list to work instead of a voicemail box, an inbox and a notepad by the register.

The bar is low, which isn't permission to be sloppy. An AI that picks up, admits it doesn't know one thing, and takes a proper message already beats what most owners do today, which is nothing. But a bluffed price does more damage than a missed call ever did. The missed call costs you one customer. The invented answer costs you the customer, the refund, and a one-star review that sits on your Google listing for three years.

Then hang up and call it yourself

This part takes ninety seconds. Ask for a live number you can dial from your own phone. Not a screen share, not a recording. A number. Call it from the truck with the radio on. Interrupt it halfway through a sentence, the way real people do. Then make three calls:

  • Ask about something next door to your service list but not on it. A two-truck window cleaning outfit gets asked about gutters constantly. Listen for whether it invents a gutter price.
  • Call back and state a wrong premise with total confidence: "Your site says you do same-day emergency work, right?" when you don't. Software that agrees with you to be pleasant will agree with your customers to be pleasant.
  • Call at 9:40 at night, demand a human, refuse to say why, and see where you end up. In the morning, check that the message waiting for you has your number in it.

If they won't give you a number to call, you've your answer, and it cost you nothing. If the rep answers all four questions cold without going away to check with engineering, somebody has asked before. Hesitation is data too. If it bluffs once across those three calls, it will bluff on a paying customer, and you won't be in the room to hear it.

The receptionist is one step in getting a customer, so ask the vendor what happens before and after the call too. Rocketship finds the buyers, emails them from your own Gmail, follows up, and books the meeting on its own. Plans that get you customers start at $24.99 a month (Launch), and every monthly plan starts with a 7-day free trial, card required. Answering your existing number is included; a dedicated line is $5 a month.
