Telephone answering and secretarial service: on site, remote or AI, how to choose

A telephone secretarial service is the service that answers in place of the business owner or practitioner, sorts the calls, notes what callers ask for and manages the resulting appointments. Four tasks sum it up: screening, taking a message, managing the calendar, confirming. This common scope makes it possible to compare the four options fairly.

Secretarial work in the broader sense goes further (post, invoicing, reminders, files), but those tasks are outside the scope of this page. A tradesperson on a roof, a practice between two patients, an agency in a meeting all have the same problem: the person who knows what to say is not available when the phone rings. Delegating means moving that moment to someone else, or to something else.

Comparing on the same scope means asking the four options the same question: who screens, who notes, who files the appointments, who confirms, and during which hours. The table sets out these criteria without any amounts, because a price only makes sense once the scope is fixed; the article on the cost of a part-time secretary details the calculation, with sources.

The employed secretary is the only one who knows the business from the inside: she understands a hint and knows who to put through first. Yet she answers only one call at a time, during the hours of her contract. The freelance secretary offers similar flexibility: you buy hours or assignments rather than a post, but you need to plan who answers during her holidays.

The human remote answering service pools operators across several clients: you gain in hours covered and in cover for absences, and you lose in detailed knowledge, because the operator knows only what their briefing sheet tells them. The AI voice agent follows the same logic with a different profile: it answers from the information you provide, says at the start that it is an AI and leaves to a person everything that falls outside its brief. The article that compares a freelance secretary with an AI voice agent digs into this face-off, and the comparison with Ubicentrex covers the one between an equipped answering service and AI.

A filter can go wrong in two directions, and the errors do not cost the same: letting a secondary call through costs an interruption, turning away a customer ready to sign costs a job. When in doubt, take a precise message with an announced callback time, or transfer.

The employed secretary judges in the moment; the operator of a remote answering service follows the list you have written; the AI voice agent also follows instructions and, when the caller asks for a person, offers a transfer to the configured number or takes a message. The article on call screening details categories and criteria; what to remember here is that the filter is written before delegating, not after the first mistakes.

A good message is judged by one test: can someone who didn’t take the call act without calling back to understand? If not, delegation has only moved the work. The article on the anatomy of a useful message lists the elements to gather; the use case on structured message taking shows what this looks like when the agent leads the exchange.

What changes from one option to another is the record. With a secretary, the message is worth as much as her notes. With a remote answering service, it arrives in the format and through the channel set out in the contract. With an AI voice agent, every call is recorded, transcribed and summarised in the workspace: you can listen to it again and see whether it led to an appointment or a contact to call back.

The appointment is where the options differ most, because it requires access to the calendar. Three decisions come before any delegation: which calendar is the reference, who can write to it, who can move or cancel. A single calendar avoids double bookings, online as well as by phone; the guide on online appointment booking details the settings.

For an AI voice agent, the calendar must be connected: appointments are entered in Google Calendar or Cal.com once the connection is made (PlayPro booking for leisure venues). If you have no booking tool, the comparison between Calendly and Cal.com helps you choose. For a secretary or an operator, access is through a shared calendar, with the rights you set.

That leaves confirmation. An appointment confirmed in advance frees a slot that can be reallocated; the article on missed appointments details the levers, and the use cases on booking and confirming appointments show what can be automated. Ask each provider whether confirmation calls are part of the service.

In a medical practice, a routine call often contains health information: a reason for consultation, a treatment, an awaited result. Health data is sensitive data under the GDPR (Article 9): the CNIL reminds us that processing it is in principle prohibited, apart from regulated exceptions. Entrusting a practice’s phone to a third party, human or software, amounts to entrusting it with this kind of information.

Two reflexes are needed. The first is professional secrecy: doctors, lawyers, notaries or court bailiffs (commissaires de justice), ask your professional body or your adviser how it applies to the people, or the tool, answering in your name, and have it written into the contract. The second is to involve your data protection officer (DPO) before signing and to ask the provider where and how the recordings, notes and calendar are hosted.

A secretarial service does not make a diagnosis, give any medical advice or assess an emergency: the practitioner writes the instruction that says what to answer when a situation seems serious, and it applies equally to an AI voice agent, which does not replace that judgement. The articles on medical remote secretarial services and on health data on the phone detail the points to check, and the guide on AI regulation on the phone sets out the general framework.

A provider that handles your calls acts in principle as a processor under the GDPR: a contract must frame the data, the sub-processors and what happens to the recordings at the end of the service. If calls are recorded, the law requires the caller to be informed: check who takes care of this.

Have what is promised put in writing: hours actually covered, time and channel for returning messages, what to do when the operator doesn’t know, length of commitment, exit terms. The article on the questions to ask before signing offers a complete checklist. Whichever option you choose, plan test calls: a simple question, a question outside the scope, a call outside opening hours, an urgent callback request.

For a self-employed professional, the difficulty is not only the volume of calls: the business phone eats into private life. The article on separating the business phone from private life offers some ideas, and the one on how the secretary’s job is changing places these tools over the long term.

Alyas offers an AI secretary designed for this case. Your existing line is kept: you forward to the agent’s number either all your calls, or only the calls that are unanswered, busy or outside opening hours, with the forwarding set up with your operator. In the evening and at weekends, the agent answers the calls you forward to it, using the information you have provided.

Whichever option you choose, preparation matters more than the choice of tool: the gain comes from clear instructions. The six steps below apply to a secretary as much as to an AI voice agent.

For practices and teams that want to try the AI option, Alyas offers AI-assisted setup: you give your website address or describe your business, a profile is prepared and you check it, then the chat agent can be tested straight away, without a phone number. The trial is free for 10 days, with no bank card; monthly plans with included minutes, starting from the entry plan, are detailed on the Pricing page.

1. Over a representative period, note every call received: who calls, about what, at what time, and what happened next.
2. Separate what requires judgement (dispute, emergency, sensitive customer) from what follows a rule (opening hours, message taking, free slots).
3. Write the instructions: who must be transferred, who leaves a message, which questions have a prepared answer, what to say when you don’t know.
4. Choose the reference calendar, connect it and decide who can create, move or cancel an appointment.
5. Choose the option, or combination, and run a short trial with test calls, including one outside opening hours.
6. Review or listen again to the first calls, correct the instructions, then set a callback deadline that you keep.
