Most explanations of an AI receptionist describe what it replaces rather than what it does. This one follows a single call from the moment the phone rings to the moment the summary lands in your inbox, and says plainly what happens at each step, what decides it, and what you had to set up beforehand for it to work.
The short version: your number forwards to a Voice Agent that has been given your services, hours, prices and rules in advance. On a call it listens, answers from those details, books into your connected calendar, and writes down what happened. Nothing is improvised, and nothing is guessed.
What you set up before any call
A Voice Agent is not a general assistant that happens to know your trade. It is given four things, and everything on a call comes from them.
- The business. Your services and the ones you do not offer, your hours, your service area, your prices or the rule you use to quote, and the answers to the questions customers ask every week.
- The calendar. A real calendar connection, the appointment types that may be booked, how long each takes, how much notice you need, and which member of staff does what.
- The rules. Which calls go through to a person, which count as an emergency, and what happens to each at 2 p.m. versus 2 a.m.
- The voice. Which voice answers, which languages are offered, and the wording of the greeting.
That is the whole setup, and the 15-minute setup guide walks through it in order. What follows is what those four things turn into on a live call.
The phone rings
The call arrives on your existing number and forwards to the Voice Agent. There is no new handset, no change to your phone system, and no app for the caller. From their side it is simply your business picking up, on the first ring, at any hour.
The greeting, including the part that is fixed
The greeting opens with your business name and a question that gets the call moving. One part is not yours to edit: the first sentence states that the caller is speaking with an AI assistant and that the call is recorded. That is a legal requirement in much of the United States rather than a product choice, and MairyAI will not switch it off. The recording disclosure sets out the reasoning.
In practice the disclosure costs far less than owners expect. Callers who want a job done keep talking, because what decides whether they stay on the line is whether the next answer is correct.
Where the answers come from
This is the step that separates a working receptionist from a demo. When a caller asks whether you service a particular brand, how much a callout costs, or whether you cover their town, the answer is read out of the business details you supplied. It is not generated from general knowledge about plumbing or clinics, and it is not invented to keep the conversation smooth.
The consequence matters: a question you answered during setup gets a confident, correct answer. A question you did not answer gets handled by your rule for unknowns, which is usually to take a message or transfer the call, rather than a plausible-sounding guess. Thin setup produces a receptionist that takes a lot of messages. Thorough setup produces one that resolves most calls on the spot.
How a booking actually happens
A booking is four things in sequence, and all four have to be true or no appointment is created.
- The job is identified. What the caller needs, matched against an appointment type you defined, with its own length and notice window.
- The time is real. The Voice Agent reads your connected calendar and offers only slots that are genuinely free, against a named member of staff who works those hours. A slot inside your notice window is never offered.
- The details you asked for are captured. Address, unit number, a gate code, a purchase order, a preferred window: each business chooses what gets asked, and the list is yours to change.
- It is read back. Before anything is confirmed, the time and the captured details are repeated to the caller and corrected if wrong. Only then is the appointment written to the calendar and a confirmation sent.
That read-back is the step most people do not expect, and it is the one that stops a wrong address or a misheard street name from becoming a wasted truck roll. The AI appointment setter page covers booking in more detail.
When the caller wants a person
Some calls should not be handled by software, and the rules you wrote decide which. A named customer asking for the owner, a supplier, a complaint, an emergency at midnight: each can be routed to a live number at the hours you choose. The transfer carries the reason for the call with it, so the person who picks up is not starting from nothing.
If nobody is available, the call becomes a callback request rather than a dead end, and it appears in your dashboard as work waiting to be done.
When nobody answers the question
A call can end without a booking and still be worth something. If a caller asks about a service you do not offer, they are told plainly instead of being booked for work you cannot do. If they ask something that was never set up, the question itself is written down, which tells you exactly what to add for next time.
What happens after the call ends
Within a minute or so of hanging up, four things exist: the recording, a written transcript, a plain-English summary of what the caller wanted and how urgent it was, and the structured details that were captured. A notification reaches whoever should see it, by email or on a phone.
This is the part owners come to rely on more than the booking. A missed call used to leave nothing behind. Now every call leaves a record that can be read in fifteen seconds, searched later, and handed to whoever does the work.
What it does not do
It does not pretend to be a person, because the disclosure rules out the question entirely. It does not call anybody: MairyAI never places outbound calls, which keeps the service clear of the rules that govern sales calls. It does not learn your business by overhearing calls; it knows what you told it. And it does not quietly improvise when it is unsure, which is why the rule for unknown questions matters as much as the answers themselves.
Seeing it on your own calls
Reading about a call is a poor substitute for hearing one. The free trial takes an email address, no card, and gives you fourteen days and fifty minutes of real calls. Point it at one line, ask it the three questions your customers ask most, and then read the records. Paid plans start at $199 a month and the full list is on the pricing page.
If you are weighing this against the alternatives, the comparison with an answering service covers outsourced human teams, and the comparison with a virtual receptionist covers the remote-assistant model.
