AI Receptionist: A Front Desk That Answers Every Call
You’re on a job site, with a patient or in the middle of the dinner rush, and the phone goes unanswered. An AI receptionist picks up for you, figures out what the caller wants, answers routine questions, books the appointment or passes along the emergency, then sends you a written summary. Sluak configures it for your business, connects it to the number you already have and keeps tuning it every month.

When to bring in an AI receptionist
The phone rarely rings at a good time: here are four situations where an agent can answer for you.
-
Can’t pick up?
With your hands full on a job or with a patient, you let your calls go to voicemail.
-
Calls coming in after hours?
At lunchtime, in the evening or on the weekend, callers get nothing but a voicemail greeting.
-
Same questions, over and over?
Hours, address, an appointment to reschedule: these simple calls interrupt you all day long.
-
An emergency slipping through?
A leak or a customer in a hurry sits among the other messages, with nothing to flag it.
What is an AI receptionist, exactly?
An AI receptionist, also called an AI phone agent, an AI voice agent or a virtual receptionist, is software that answers the phone with a synthetic voice. There’s no “press 1, press 2” menu: callers talk the way they normally would, and the agent understands the request, answers from the information you’ve given it, and takes action.
- 1UnderstandThe request, in the caller’s own wordsListening
- 2ActAppointment, message, transfer to youActions
- 3Report backA written summary after every callFollow-up
The agent doesn’t replace a person for delicate conversations: it absorbs the repetitive calls and the ones that come at the wrong moment. When a request goes beyond what it can handle, it says so, takes a complete message and passes it on to you. The same principles apply to your email with our assistant for your inbox.
What the agent does during a call
Each feature is set up separately, on your current number and with your calendar. You can start with greeting callers and taking messages, then add appointments.
-
01
Pick up every call
No call goes unanswered
The agent answers every call forwarded to it, including when several people call at once, within the capacity of the platform we choose.
-
02
Answer routine questions
Based on your information
Hours, address, directions, services, what to bring: it answers from what you’ve provided and never makes anything up.
-
03
Book and reschedule appointments
Connected to your calendar
It offers open slots, books the appointment, moves or cancels it, and can send a confirmation by text.
-
04
Sort requests
One rule per call reason
Emergency, quote, general question, complaint: the agent asks the right questions, categorizes the call and applies the rule you’ve set.
-
05
Hand off to a human
The context follows the call
Emergency, key customer, sensitive request: it transfers the call to the number you’ve chosen, along with the context, so no one has to explain everything twice.
-
06
Leave a written record
A summary for every call
The summary arrives by email or text: who called, why, what was agreed and what’s left to do.
Which businesses is an AI receptionist for?
Those that get a lot of calls and have their hands full when the phone rings. Auto shops, hair salons: plenty of other businesses are just as good a fit.
Contractors and home service pros
Landing jobs often starts with a call answered at the right moment. The agent takes down the quote request and sends you emergencies right away, spotted using your criteria.
“I’ve got a leak under the sink, can you come out?”
Physical therapists, chiropractors, dentists and medical practices
It books, reschedules and cancels appointments, alongside a medical answering service. It gives no medical advice and directs callers to 911 in a life-threatening emergency.
“I need to move my Tuesday session.”
Restaurants
During the rush, the agent takes reservations and answers questions about hours and the menu. It works alongside the restaurant’s online booking.
“A table for four, Saturday at 8?”
Hotels, inns and bed-and-breakfasts
Availability, posted rates, check-in time, parking, pets: it answers late at night and, depending on the platform we choose, in other languages.
“Can we check in after 10 p.m.?”
Real estate agencies
Every listing makes the phone ring. The agent identifies the property, qualifies the caller (buying or renting, budget, timeline) and offers a showing time.
“Is the two-bedroom still available for rent?”
Law firms and consulting practices
The agent handles intake: the reason for the call, an appointment, a summary sent to the firm. It never gives legal advice.
“I’d like to schedule an initial consultation.”
What a call sounds like, industry by industry
Four short exchanges. In each one, the agent says it’s an AI in its very first sentence: that’s our default, explained further down.

Law firmWednesday · 11:15 AM
AI agentHello, I’m an AI, the firm’s virtual assistant. What is your call about?
CallerA dispute with my employer. I’d rather talk to someone about it.
AI agentI understand. I’m transferring you to the front office, along with the reason for your call.
Setup, step by step
An AI receptionist is only as good as its preparation. Five steps, each closed out with a deliverable you approve before the next one begins.
-
01Before any configuration
Listening to your current calls
An interview and, if possible, a few days of call logging: who calls, at what time, for what reasons, which questions keep coming up, which calls absolutely have to reach you.
Deliverable: Your call map: reasons, priorities, what the agent handles and what it passes on
-
02After the interview
Script and knowledge base
We write the greeting (including the statement that it’s an AI), the questions to ask for each call reason, the approved answers, the transfer rules and the wording to avoid. We also choose the voice and the tone.
Deliverable: The call script, reviewed and approved by you
-
03Once the script is approved
Connections
Call forwarding from your current number (all calls, the ones you don’t answer, or after hours only), a connection to your calendar and, where possible, to your industry software, and delivery of the summaries.
Deliverable: The forwarding diagram and the list of access set up
-
04Before go-live
Testing
Test calls on real, difficult cases: an emergency, an unhappy customer, an off-topic question, a caller asking for a human, a strong accent, a bad connection. Every gap gets fixed in the script.
Deliverable: The test report
-
05Every month
Go-live and follow-up
A read-through of a sample of summaries, new questions added, transfer rules adjusted, a look at the calls that were misunderstood.
Deliverable: The monthly check-in and the fixes made
Your number doesn’t change: your customers dial the same one as before. You can take back control at any time by turning off call forwarding.
Voicemail, answering service or AI receptionist: which should you choose?
An AI receptionist sits between voicemail, which only records, and a live answering service, where a person picks up for you.
| Criterion | Voicemail or phone menu | Live answering service | AI receptionist |
|---|---|---|---|
| Availability | Around the clock, for a message only | During the service’s hours | Around the clock, with a real answer |
| Understanding | None, or a keypad menu | Complete, with judgment | Good on what’s planned for, limited on the unexpected |
| Actions | None | Appointments, messages, transfers | The same, plus a written summary |
| Delicate conversations | Not suited | Where a human shines | To be transferred to a person |
| Cost | Low | Based on time spent and call volume | Based on minutes or calls |
Many businesses combine the two: the AI receptionist takes the simple calls and the evening ones, while a person keeps the key customers and the sensitive situations. The company’s phone system stays the same; only the way calls get answered changes.
AI disclosure, call recording, data: your responsibilities
Four points to settle before go-live. They don’t replace advice from your attorney or your privacy officer, whom we’re glad to bring into the project.
The agent says it’s an AI
Our agents announce it in their first sentence: that’s Sluak’s default, wherever you are. In the European Union, it’s mandatory: the EU Artificial Intelligence Act requires, as of August 2, 2026, that anyone interacting with an AI be clearly informed, at the latest at the time of the first interaction, unless it’s obvious to them.
Recording is disclosed
If calls are recorded, tell the caller at the start of the call and check the rules that apply where you and your callers are located. We suggest recording only when it’s useful: the written summary is often enough.
Health: only what’s needed
Health information is especially sensitive, and stricter rules often apply to it. For a practice, the agent collects only what it takes to book the appointment, without asking for details about symptoms.
A platform vetted with you
It processes personal data on your behalf: together we check where it hosts that data, how long it keeps it and what its contract says.
Your questions: AI Receptionist
Can’t find your question? Ask us
Does the caller know they’re talking to an AI?
Yes. The agent says so in its first sentence. That’s our default everywhere, and in the European Union the AI Act requires it for systems that interact directly with people. The caller can ask to speak with someone at any time; depending on your rules, the agent transfers the call or takes a message.
Do I need to change my phone number?
No. You keep your number and your carrier: we set up call forwarding to the agent, for all calls, for the ones you don’t answer, or only outside your business hours. Switch forwarding off and everything goes back to the way it was.
Can the agent handle several calls at once?
Yes, within the limits of the platform we choose. We check that capacity with you before go-live, against the hours when your calls peak, which we log in the first step.
What if the agent doesn’t understand the request?
It says so, rephrases or asks one more question. If it still can’t work it out, it takes the caller’s contact details and the reason for the call, then sends you a complete message, or transfers the call if you’ve set that up. These cases are reviewed during the monthly follow-up to improve the script.
Can the agent book appointments in my calendar?
Yes, if your calendar or scheduling software allows a connection, which we check in the first conversation. If not, the agent takes down the request and the preferred time, and you confirm it yourself.
Are conversations recorded?
That’s your call. A written summary is often enough. If you choose to record, every caller is told at the start of the call, and why, and the retention period is set in advance. We also check with you the rules that apply where you and your callers are.
Does the agent speak languages other than English?
That depends on the platform we choose. We check with you which languages it supports and test each one before go-live.
Does an AI receptionist replace a human receptionist?
No. It takes the repetitive calls and the ones that come in when no one’s available. A receptionist or an answering service is still valuable for greeting people in person, handling delicate cases and anything that calls for judgment; the agent frees up their time for exactly that.
How much does an AI receptionist cost?
We work by quote, in two parts: setup, then ongoing operation, which voice platforms generally bill per minute of conversation or per call. The first conversation is for estimating both from your actual calls, with no commitment on your side. Two services often go with it: visibility on Google Maps, to get more calls in the first place, and our agent that replies to Google reviews.
