Understanding
What an AI voice agent is, how it works, and answers to the questions people ask before adopting one.
AI voice agents: how they work
Between the moment the caller says “hello” and the moment you receive the summary, five building blocks work one after another, several times a second. Here is what they do, why latency and safeguards matter more than the voice, and what you should ask a provider.

AI voice agents: the FAQ for small businesses
Since we started setting up voice agents for tradespeople, practices, agencies and shops, the same questions keep coming up, in the same order: does it really work, how much does it cost, what happens to my number, and what happens when it doesn't understand. Here are the answers, short and grouped by theme.

Numbers and call forwarding
Keeping your number, forwarding your calls operator by operator, connecting a phone system.
Calendars and appointments
Booking appointments by phone, preparing your calendar and reducing forgotten appointments.
Booking appointments by phone: best practice
A well-booked appointment means a patient or customer who turns up, on time, with what they need, and a calendar that doesn't contradict itself. Whether it's you, a receptionist or a voice agent answering, the rules are the same. Here is the script, the questions in the right order, and the calendar settings that prevent gaps and double bookings.

Setting up Google Calendar for appointment booking
A voice agent only offers what your calendar shows it as free. If Google Calendar tells the truth, the phone will too; if it lies by omission, with a forgotten break or badly entered time off, the appointment will land at the wrong moment. Here is how to prepare Google Calendar, setting by setting, before handing your appointments over to an agent.

Appointment booking with Microsoft 365 or Cal.com
Many practices and agencies live in Outlook; others have chosen Cal.com for their online booking page. Either way, a voice agent can book appointments over the phone, provided the calendar tells the truth and the rules are written down. Here are the settings to check, tool by tool.

Confirmation SMS and missed appointments
A missed appointment is rarely ill will: it is forgetfulness, a misunderstanding, or something that came up and the customer didn't manage to tell you about. Three well-written SMS, sent at the right time, deal with those three causes. Here is what they should say, ready-to-adapt examples, and when to send them.

Phone bookings with AI: a guide for restaurants
A restaurant's phone rings at the worst possible moment: in the middle of the rush, when nobody can leave the dining room or the pass. An AI can take these bookings for you, provided you give it clear rules. Here is what it asks, what it applies, what it passes on, and what you are better off keeping for yourself.

Organising phone answering
Peak hours, seasons, time off, evenings and weekends, foreign languages: answering every call without spending your days on it.
Phone peak hours: the method
The phone doesn't ring the same way all day. It goes quiet for hours, then everyone calls the moment you open, when you're serving, when you're handing vehicles back. Here is how to spot those time slots with a simple log, then set up overflow so that someone answers every time.

Seasonal call peaks: spotting and absorbing them
Every trade has its weeks when the phone never stops: the festive season for florists, the first cold snap for heating engineers, summer for hotels. These peaks come back every year, at roughly the same dates, and that's good news: you can prepare for them. Here is how to spot them, size your phone answering and write the answers before the wave arrives.

Holidays and closures: how should you handle the phone?
Closing for the holidays doesn't mean shutting off the phone. While you're away, customers call to find out when you reopen, to book an appointment for when you're back, sometimes for an emergency. Here is how to prepare the closure, choose what callers find at the other end of the line, and get back to work without being buried in messages.

Answering calls in the evening and at weekends
Your customers don't only call during your opening hours. Many can only do so after work, on Saturdays or on public holidays, and some have an emergency that won't wait until Monday. Here is what a voice agent can do for them when you're closed, the transfer rules to write for emergencies, and what it must never do.

Multilingual phone answering for a small business
A tourist booking a table, a traveller announcing a late arrival, a foreign customer asking for a quote: on the phone, with no gestures or writing to help, the language barrier weighs more than at the counter. Here is what changes when the call isn't in your language, the solutions within reach of a small business, and how to prepare your information so that it gets across in every language.

AI voice agent and reception team: working together
A voice agent doesn't replace your reception: it takes the calls the team can't take, at the moment it can't take them. You still need to decide who does what. Here is how to share out calls, set up transfers and organise feedback, so that the agent backs up your teams and never replaces them.

Self-employed: answering the phone without stopping work
When you work alone, every ring raises the same question: answer and interrupt the session, the appointment or the job, or let it ring and risk losing a customer. There is a third way: decide in advance which calls deserve an interruption, and organise an answer for all the others.

Professional voicemail greetings: examples by trade
A good voicemail greeting won't bring back lost calls, but it saves some of them: it says who you are, when you'll call back and what the caller can do right now. Here are the rules, ten greetings by trade to adapt, and what changes when an agent answers instead of voicemail.

Handling calls
The right questions, filtering sales calls, emergencies, scripts, calling back and the CRM.
Qualifying incoming calls: the right questions
You can tell a well-qualified call after the event: the person calling back has everything they need, and doesn't have to ask the questions again. A badly qualified call leaves a name, a number and “call back”. Here are the questions to ask for each type of call, what the summary should contain, and how to use it to decide who to call back first.

Filtering sales calls without losing customers
Sales calls clog up the line and interrupt your work. But filtering too harshly does more harm: it turns away the customer who starts clumsily, or the business calling to become a customer. Here is how to tell the two apart from the first few sentences, write rules that everyone applies the same way, and keep a record of every call turned away.

Handling urgent calls as a tradesperson
For a tradesperson, every call sounds urgent, and few really are. The risk isn't missing a quote: it's leaving a leak, a heating breakdown in the middle of winter or someone locked out waiting behind ten ordinary requests. Here is how to define an emergency, the questions that reveal it, and the transfer rules, by day and by night.

Phone greeting scripts: examples by trade
A greeting script isn't a text to recite: it's the order of the sentences when you answer, so that every call ends with an answer, an appointment or a complete message. Here is the five-step outline, four examples to adapt by trade, and what changes when an AI agent answers.

Calling a customer back: making the most of the call summary
When a voice agent has taken the call, the callback no longer starts from scratch: you know who called, why, what has already been done and what is left to do. You still need to read the right information, in the right order. Here is how to make the most of the summary, the transcript and the recording, decide who to call back first and prepare what you are going to say.

AI voice agent and CRM: Sellsy, monday.com, webhooks
A well-handled call shouldn't stay in an inbox. With a voice agent, it can reach the customer's record in your tools, with no re-keying. Here is exactly what the native Sellsy and monday.com integrations do, what webhooks carry for all other software, and how to choose.

Rules and data
AI Act, GDPR, call recording, health data hosting: what the rules say, simply.
AI on the phone: the AI Act, GDPR and your obligations
Having an artificial intelligence answer your customers is legal, under four conditions that fit on one page: say that it's an AI, inform callers about their data, put a contract in place with the provider and, for healthcare, host data within a certified framework. Here are the texts, and what they change in practice for a small business.

Telling callers it's an AI: ready-to-use phrases
Telling a caller they're talking to an artificial intelligence takes one sentence. What matters is the timing, the tone and what comes straight after: what the agent can do, and how to reach a human. Here is the structure that works, phrases to adapt by trade and the mistakes that make people hang up.

GDPR and recording business calls
Recording your business's calls is allowed, but not “just in case”. You need a specific reason, clear information for the caller, a short retention period and restricted access. Here are the guidelines published by the CNIL, the French data protection authority, what they change for a small business, and how to apply them with a voice agent.

Pricing and getting started
Prices, measuring lost calls, and the first days with a voice agent.
How much does a missed call cost? The calculation
A missed call doesn't cost so many euros “on average”: it costs what it would have earned you, and nobody knows that better than you. Here is a four-line method to put a figure on it with your own data, and the levers, from the simplest to the most complete, to reduce the loss.

Measuring your missed calls in one week
Before putting a figure on what your missed calls cost you, you need to know how many there are, when they come in and why nobody answered. Your phone, your operator and your broadband box/router already hold a good part of the answer. Here is where to find it, and a one-week log sheet to record it.

The first 14 days with an AI voice agent
A successful trial isn't just a matter of plugging in the agent and waiting. It takes preparation: a few settings on day one, test calls, then a careful read of the summaries to correct whatever needs correcting. Here is the checklist, step by step, up to the decision.

Choosing your AI voice agent's voice
The voice is the first thing your callers hear, even before your business's name. It isn't chosen on taste: it is chosen according to your trade and your customers, then listened to in real conditions. Here is how to choose the tone, what to listen for during the “Test call” and during the trial, and when to change it.

Tradespeople: stop missing calls
A tradesperson's phone rings when their hands are in a wall, their head is under a sink or their foot is on the accelerator. Missing the call often means losing the job to the next name on the list. Here is a six-step method, from the simplest to the most complete, so that every call gets an answer.

Phone answering for therapy and allied health practices
In a therapy or allied health practice, the practitioner's hands are busy all day, and the phone rings during sessions. The calls are much alike: a course of sessions to schedule, a session to move, a new patient, a waiting list that keeps growing. Here is how to organise phone answering without a full-time receptionist, and what you need to know about health data.
