Why Do AI Receptionists Fail? What Goes Wrong and How to Check Yours
Why do AI receptionists fail? Usually the setup: what the AI answering service was told, what it knew, and whether anyone tested it. How to check yours.
TL;DR
- AI receptionists usually fail because of the setup, not the voice technology: what they were allowed to say, what they knew, and whether anyone tested them.
- The common mistakes: invented prices or policies, promises you can't keep, wrong hours, urgent calls handled as routine, and bookings when you don't work.
- The fix: answers from your own list, a message when the answer isn't there, instructions for each kind of call, test calls, then reading every call's notes.
- In Juney, each fix is a setting in the phone app, and you can call her yourself any time.

When an answering service gets a call wrong, the caller doesn't blame the software. They blame your business, and they ring someone else next time. Most of these mistakes show up on a few test calls, if you make them before a customer does.
Why do AI receptionists fail?
An AI receptionist (or AI answering service) fails when it says something nobody gave it, works from details that are out of date, or meets a call nobody told it how to handle. The voice side is rarely the weak point now. The setup is: what it's allowed to say, what it knows about your business, and whether anyone rang it before customers did.
That's why two businesses on the same technology can get very different results. A rushed setup leaves gaps, and the AI fills them with confident guesses. A careful one gives it your answers and a safe default for everything else. You can see what a well set up call looks like in how Juney handles a call, from greeting to summary.
What does an AI receptionist get wrong most often?
Five mistakes do the most damage on a small-business line, and each one traces back to a gap in the setup.
| The mistake | What the caller hears | The usual setup gap |
|---|---|---|
| Invented price or policy | "Our service call fee is $60" when it's $95, or a refund rule you never had | No list of prices and answers, or nothing telling it to take a message when it doesn't know |
| A promise you can't keep | "Someone will be there within the hour" | No wording of yours for what happens next |
| Wrong hours | "We're open Saturday" when you're not | Hours copied from an old website, or a holiday nobody added |
| Urgent call handled as routine | "I'll pass that on" to a caller with water coming through the ceiling | No instructions for emergencies, or examples that don't match how callers talk |
| Booking at a time you don't work | A job booked for Sunday morning | A calendar that shows your days off as free |
What happens when an AI receptionist gives wrong information?
Callers believe it and act on it, and you're left to put it right. The cleanest recent example isn't a phone line: in April 2025, Ars Technica reported that an AI agent answering support email for Cursor, the maker of a code editor, told a user that being logged out on a second computer was expected under a new policy: one device per subscription. No such policy existed, and the agent, called Sam, wasn't a person. Some users announced they were canceling before the company replied that the answer was wrong.
Two setup lessons sit in that story. It had no true answer for an unexpected logout, so it produced a plausible one. And people didn't know it was AI, so they took its word as policy. The company said afterwards that its AI email replies are now clearly labeled.
A similar mistake has ended up before a tribunal. In February 2024, a Canadian tribunal ordered Air Canada to compensate a customer over a fare policy its website chatbot described wrongly.
What to do: give your answering service a list of answers and a safe default for everything else. In Juney, answers live under FAQs, and she says them word for word. Anything not on the list becomes a message for you, not a guess. Introduce her as your AI assistant in your greeting, so nobody mistakes her for you.
Can an AI receptionist promise something you can't deliver?
Yes, if it has room to improvise. A promise doesn't have to be a price. "We'll have someone out tonight", "that's covered by the warranty" and "we can match that quote" are all promises, and the caller will hold you to them.
Price is the classic version. In December 2023, VentureBeat reported that a car dealership's website chatbot was talked into "agreeing" to sell a 2024 Tahoe for $1, which we cover in Can an AI Answering Service Answer Price Questions and Objections?. It was a prank, but the gap was real: the bot could say prices nobody had given it.
What to do: write down what callers should hear about next steps, in your words. A line such as "We'll call you back within the hour" tells the caller what to expect, if it's true. In Juney, a Tells them line in a scenario is said word for word, and she only quotes the prices you list under Services & pricing. Leave a price blank and she tells callers you'll confirm it. She doesn't make up safety, repair or pricing advice: any advice callers hear is what you wrote.
Why does it give out the wrong hours or old prices?
Because it learned them from somewhere out of date and nobody checked. Many services, Juney included, start by reading your website. If the site still lists last year's service call fee or the Saturday hours you dropped, your answering service will repeat them to callers.
Hours go wrong in quieter ways too. A public holiday nobody set, a week off that isn't in the app, or a time zone set to the wrong city shifts everything that depends on your hours.
What to do: go through every price and answer it learned, line by line, and delete what isn't true today. Check service call fees and the areas you cover first; callers push back on those most. In Juney, set your weekly hours under Hours, choose a rule for public holidays, add your own days off, and check Settings → Time zone.
Why does an urgent call get treated like a routine one?
Usually because it has no instructions for urgent calls, or the instructions don't match how callers actually talk. A caller rarely says "this is an emergency". They say "water's coming through the light fixture" or "there's no heat and I've got a baby at home".
In Juney, each kind of call is a scenario: a name, examples under When they say something like, and what she does. If a call matches nothing, she takes a message. That's a safe default for a supplier, and the wrong one for a burst pipe.
Three other gaps send urgent calls to the wrong place:
- The put-through number isn't monitored. Choose someone who can take urgent calls and test the handoff before relying on it.
- Nobody answers the put-through number. Juney rings it first, and if nobody takes the call within 20 seconds, she comes back and takes a message instead.
- The call came in while she was taking voicemail. On a voicemail call the caller leaves a recorded message, and she doesn't put anyone through.
What to do: add an emergency scenario with five or six phrases your callers really use, and point it at a number someone answers. If you work alone, choose Ring me first in Ringing mode to have the Juney app ring you for about 15 seconds before she answers. Stay signed in; if the app can't be reached, she answers. For anything involving safety, like gas or a downed power line, copy the wording your utility or emergency service publishes into the scenario rather than writing your own.
Why does it book jobs at times you don't work?
Because it can only see what your calendar and hours tell it. Juney offers bookings inside the hours you set, and she offers times that show as free in your Google Calendar. A Sunday you never work, or a dentist appointment you kept in your head, looks free unless it's blocked out.
What to do: block out the hours and days you don't work in your calendar, because she checks you're free before she books. Set a booking length that fits most of your jobs. And check which scenarios have Uses your calendar: only those produce a real booking, and everything else becomes a message.
Why do AI receptionists that worked last week start getting it wrong?
Something changed and nobody tested it again. In January 2024, the BBC reported that the online support chat of DPD, a large parcel delivery company, swore at a customer and wrote a poem criticizing the firm. DPD blamed a system update and switched that part of the chat off. It's a big company's website chat, not a small business's phone line, but the lesson carries: every change is a reason to test again.
For a small business, the changes are usually yours: a new price, new hours, a new scenario. Juney applies changes from the next call, so ring her after each one.
What if calls never reach the AI?
With no-answer forwarding, your phone or voicemail can take a call before your carrier sends it to the service. Verizon advises turning off Live Voicemail for conditional forwarding, and Google says automatically screened calls won't be forwarded.
What to do: use the forwarding setup your service requires, then call your number from another phone. Juney uses all-calls forwarding, so the carrier sends the call on before your phone rings.
How do you check your AI receptionist before customers do?
Ring it yourself, ask what your customers ask, then read every real call closely for the first week. Fix the setting behind each mistake, not just the call.
Aim your test calls at the failures above:
- A question you never answered. It should take a message, not invent an answer.
- An emergency, in a caller's words. It should follow your emergency instructions.
- A booking on a day you don't work. It shouldn't offer that day.
- A push for a discount or a promise. You should hear your line, or that someone will call back.

In Juney, tap Call her yourself in the Juney tab, as often as you like. A test call gets the full conversation at any hour, and it stays out of your Calls tab. Once real calls arrive, read each full transcript in the Calls tab, because a short summary can hide a wrong answer. Calls that need a follow-up carry a Needs you tag.
What does a properly set up AI answering service do differently?
It says what you gave it, takes a message when it doesn't know, follows your instructions for each kind of call, and gets checked before and after it goes live. None of that needs a specialist if the setup walks you through it. The full order of steps is in How to Set Up an AI Answering Service Properly, Even From Your Phone.
Juney's setup runs on your phone, with no computer and no dashboard. She reads your website, you correct what she learned, you hear her on a test call, you set what happens for each kind of call, and you forward your calls. Then every call comes back as a summary and transcript, so a mistake is easy to spot and fix. Good setup makes her reliable; reading the call notes keeps her that way. Juney is built by Trillet, the voice AI platform trusted by over 4,000 businesses.
Frequently Asked Questions
Who is responsible when an AI receptionist gives a caller wrong information?
Treat it as your business's word. In the Air Canada case of February 2024, the tribunal held the airline responsible for what its website chatbot told a customer. Check what your answering service says before callers rely on it.
How often should I test my AI receptionist?
Before it takes its first real call, after every change you make, and whenever your prices, hours or services change. Read every call in full for the first week.
What should I do after a caller got a wrong answer?
Read that call's transcript, and play the recording if Record calls is on, to see exactly what was said. Fix the setting behind it, such as a price, an answer, your hours or a scenario, then make a test call and ask the same thing. You can ring the caller back from the call's summary.
Why did my AI receptionist say something I never told it?
With Juney, check what she learned from your website during setup. She may have picked up services, prices and answers there. Check Services & pricing and FAQs line by line, and delete whatever is out of date.
Updated for October 2026: added forwarding checks for calls that don't reach the service.
