AI voice agents and receptionists for businesses
An AI voice agent is a phone assistant that answers and makes calls on behalf of your business and speaks naturally. It understands what callers want, sorts it out — a booking, an appointment, a question — and, when a person is needed, transfers the call with the context already gathered. Nertel builds each one around the business it serves.
How it works inside
What happens when a customer calls
Each piece does one job and hands over to the next, just like an automation workflow. Here’s how yours works, step by step.
- Trigger: Incoming call (Business phone)
- AI agent: AI voice agent (Understands, solves) — Knowledge, Memory, Tools
- Action: Appointment booked (Calendar)
- Action: Customer record (CRM)
- Action: Confirmation (WhatsApp)
- Action: Hands over to a person (With a summary)
What it does
What your AI voice agent does
Answers every call
It picks up on the first ring, at any hour, even when several calls come in at once. Nobody is left on hold.
Makes calls for you
It confirms and reminds appointments, follows up with customers and calls the contacts in a campaign, always within what the regulations allow.
Your switchboard and AI receptionist
It understands what the caller wants and puts them through to the right person or department, with no “press 1” menus.
Speaks your customer’s language
It speaks more than 70 languages, Catalan included, and if the caller switches language, it switches too.
Everything lands in your systems
Bookings, appointments and customer records go straight into the tools you already use, with no manual re-keying.
With your brand’s voice
You choose the voice and tone, how it greets callers and how it handles each case. And, if you like, a unique voice created for your brand.

Questions
Frequently asked questions
What is an AI voice agent?
It is an assistant that answers and makes phone calls, speaking like a person. It understands what callers say, responds with your company’s information and handles tasks such as taking a booking, scheduling an appointment or logging an issue.
How is it different from a traditional phone system?
A traditional switchboard routes calls through keypad menus and resolves nothing. A voice agent understands what the caller needs, handles the questions that come up every day and only passes to a person what genuinely needs one, with the context already gathered.
Can a voice agent speak Catalan?
Yes. It speaks Catalan naturally, as well as Spanish, English, French and more than 70 languages in all. It detects the caller’s language — from the phone number’s country code and from how they speak — and replies in that language.
Do callers know they are talking to an agent?
Yes. The agent introduces itself as your company’s virtual assistant, as European regulations require.
How long does it take to get up and running?
Usually one to two weeks from when you tell us how you work. The Nertel team builds it, connects it and gets it running: you don’t need any technical staff on your side.
When is an AI voice agent not worth it?
If you receive few calls and someone is always free to pick up, it adds little. It makes the difference when the phone keeps interrupting work, when calls come in out of hours or when the same questions come up every day.
