Answering Service: What It Is, the Three Types, and How to Choose
When the line is busy, when you are with a customer, or when the call comes in after closing time, someone has to answer — otherwise the customer, very often, simply calls the next business. That is the gap an answering service fills. In this guide we explain in plain terms what it is, the forms it takes today — from the answering machine to the AI receptionist — what it costs, and what is worth checking before you choose.

What is an answering service?
An answering service is any service that answers the phone on behalf of a business when the business itself cannot, or cannot keep up. Its traditional form is the telephone answering service with live operators: an external team that picks up, takes the customer's details and passes the message on to you. In recent years the same term also covers the newer AI-based solutions, which do not just take a message but hold a conversation with the customer and book the appointment.
Who is it for? Mainly small businesses that live off the phone and the appointment book: medical and dental practices, hair salons, physiotherapy clinics, garages, law offices. It matters most where the professional answers the phone personally, between customers: every working hour is also an hour the line goes uncovered — and an unanswered call is usually a customer who went elsewhere.
The three types: answering machine, live operators, AI receptionist
Behind the term "answering service" sit three very different solutions. None is "the best" for everyone — each fits a different business.
The answering machine (voicemail) plays a recorded message and records whatever the caller says. It does not converse and does not book appointments — the actual service is postponed until you listen to the messages and call the customer back. It is the simplest option, and it is enough when your calls are few and you have the time to return every one.
The live answering service is staffed by people who answer on your behalf, in shifts. They take the customer's details and usually leave you a message, so that you book the appointment yourself afterwards. Coverage goes as far as the shifts go, and billing is typically per call or by call bundle. It fits when your calls often need human judgment and handling beyond booking an appointment.
The AI receptionist is software that converses with the customer in natural language — no option menus, no recorded message. It understands what the caller wants and completes the appointment within the call itself, directly in the business's calendar; when a matter needs your eyes, it takes a message and lets you know. It answers around the clock, with the same quality at every hour. It fits when most of your calls are "I'd like to book an appointment." To go deeper, see our guide on what an AI receptionist is.
| Answering machine | Live operators | AI receptionist | |
|---|---|---|---|
| How it answers | Recorded message | A person on shift | Natural-language conversation |
| Availability | Always — but it only records | As far as the shifts go | Around the clock |
| Appointments | No — message only | Usually a message; you book afterwards | Booked within the call itself |
| Fits when… | Not losing the message is enough | Calls need human judgment | Calls are mostly appointments |
And one honest footnote: no technology should handle matters that call for human judgment on its own. A serious AI receptionist knows where to stop — it keeps the caller's details and request, and the matter reaches you.
How much does an answering service cost?
The most useful point of reference is the alternative that covers the phone completely: a full-time secretary. According to published job listings, her net salary usually runs at €850–€1,200 per month, while the salary data on mywage.gr shows a range of €671–€1,556 — plus employer contributions and statutory bonuses. And she covers, of course, only her working hours.
Answering services are, as a rule, considerably cheaper than hiring — but each with its own billing logic. Live answering services usually charge per call or by monthly bundle; for the market picture and the fine print of the offers, see our detailed guide on live answering service pricing. For the comparison between an AI receptionist and a hire, there is a separate guide: AI receptionist or a salaried secretary?
The essential question, though, is not only "what does it cost" but also "what does it cost not to have one": in an appointment-based business, an unanswered call is very often a lost appointment.
What to check before you choose
- Natural Greek. If you are considering an AI solution, do not settle for promises — ask to hear it in a real conversation. Greek is a demanding language for voice systems, and the difference is audible from the first sentence. On parousa.com, for example, you can listen to a real recorded sample call.
- GDPR and recording. Ask whether the conversation is recorded, where the data is stored and for what purpose it is used. Parousa, for example, does not record the conversation and uses the call details only to manage the appointment.
- Does it introduce itself as a digital assistant? The European rules on artificial intelligence require the caller to know they are talking to an AI system. A provider that passes it off as human exposes you.
- Appointment within the call, or a message? "We take a message and you call back" is one thing; "the appointment is booked here and now, in your calendar" is another. Ask which calendars it connects to — Parousa books appointments directly into Google Calendar, with Outlook and Apple Calendar coming soon.
- Do you keep your number? The right solution works with simple call forwarding — when the line is busy, outside opening hours, or on missed calls — with no new number and no new equipment.
- A trial before you commit. A trial with real scenarios from your own business says more than any presentation.
Frequently asked questions
What is an answering service?
A service that answers the phone on behalf of a business when the business cannot keep up. Its traditional form is the live answering service with human operators; today there are also AI-based solutions that converse with the customer and book the appointment within the call itself.
How does an answering service differ from an answering machine?
The answering machine simply records a message — the actual service is postponed. An answering service genuinely answers: either with a person (live operators) or with an AI receptionist that converses and can complete the appointment within the call.
How much does an answering service cost?
It depends on the type: live answering services usually charge per call or by call bundle. As a point of reference, a full-time secretary is usually paid €850–€1,200 net per month according to published job listings (mywage.gr range: €671–€1,556), plus contributions and statutory bonuses — answering services are, as a rule, considerably cheaper than hiring.
Do I need a new phone number or new equipment?
No. You keep the number your customers already know and forward to the service only the calls you cannot take — when the line is busy, outside opening hours, or on missed calls. No new equipment is needed.
Will the customer realise they are talking to an AI?
Yes — and that is how it should be. The European rules on artificial intelligence require the caller to know they are talking to an AI system. Parousa always introduces itself as a digital assistant, does not record the conversation, and uses the call details only to manage the appointment.
