AI call answering

What does an AI phone agent do for a business in Spain?

It answers the calls you would otherwise miss — at the front desk, in the lunch rush, after the last guest has gone to bed — and deals with them the way a good receptionist would: a booking, a message, or a transfer to you. Callers can speak Spanish or English and, in Catalonia, the Basque Country and Galicia, their own language.

Many of the calls a business in Spain receives come from people who do not speak Spanish as a first language: holidaymakers, residents from northern Europe, foreign buyers, students. An agent that answers in the caller's language, at any hour, stops those calls turning into a lost booking or an unanswered enquiry.

  • Bookings go into your calendar through Cal.com, or into your own system through its API.
  • Questions about opening hours, menus, treatments and directions are answered from your website and documents.
  • Every call has a transcript and an outcome. More on how it works on the AI receptionist page.

Voices

Can the agent speak Spanish, Catalan, Basque and Galician?

Yes. Voice agents speak Spanish, Catalan, Basque, Galician and English, and you choose the voice from a searchable library and listen before you pick. Replies on WhatsApp and website chat run in 37 languages: Spanish and English are among them, Catalan, Basque and Galician are not.

Voice agents also speak French, German, Italian, Portuguese, Dutch and many more, so a Dutch couple on holiday in Málaga can be answered in Dutch. A caller who is more at ease in another language can be answered in it.

To be straight about the limits: we have not published how each voice sounds in each region. Listen in the library, ring your agent from the browser, and have someone who speaks the language as their own try it before you connect your number. In Catalan, Basque and Galician areas, chat and WhatsApp replies run in Spanish or English.

Data

Where is my data stored, and what about GDPR?

Each workspace keeps its data in the region it is set up in. We also support region deployments for enterprise customers.

Calls are processed partly in other countries — speech recognition in the EU, the voice and the language model in the US — under transfer safeguards. That does not settle your own duties under the GDPR and Spain's data-protection law, whose supervisory authority is the AEPD. The privacy policy sets out the detail.

You remain responsible for telling callers how their data is used, including that a call is recorded if you switch recording on (it is off by default). The agent's opening line is yours to write, so it can say so at the start of every call. Read the official text; not legal advice.

Your number

Can I keep my existing Spanish number?

Yes, if the number lives on a Twilio, Telnyx or Plivo account you hold: connect the account and the agent answers that number. We don't sell Spanish numbers.

  • Number with another phone provider? Port it to one of those accounts, or forward your calls to a number you hold there.
  • Transfer to a person and voicemail detection work on Plivo and Telnyx numbers. An imported Twilio number answers and records, but can't transfer or detect voicemail.
  • Telnyx calls only the countries switched on in your outbound voice profile — the US and Canada by default — so add Spain before making outbound calls.

Examples

Which businesses in Spain is it built for?

Businesses whose phone rings while they are busy with a customer, and above all those with international customers: hotels, holiday rentals, restaurants, clinics, estate agents and advisers.

01 — Madrid

Adviser for foreign residents

New enquiries taken down in full, consultations booked in English or Spanish, and the agent set never to give legal or tax advice.

02 — Barcelona

Private dental clinic

Check-ups and hygienist visits booked and moved in Catalan, Spanish or English; anything clinical handed to the practice team.

03 — Valencia

Holiday-rental manager

Guests asking about check-in times, parking and the Wi-Fi get the same answers from the property guide, in their own language, at any hour.

04 — Seville

Restaurant and flamenco venue

Table and show bookings by phone, menu and allergen questions answered from the menu you upload, and group requests passed to the manager.

05 — Málaga

Estate agent for foreign buyers

Viewing requests from abroad qualified in English, the buyer's budget and timing noted, and the details handed to the right agent.

06 — Palma

Boutique hotel

Late-evening calls from guests and prospects answered, transfer and table requests logged, and the message waiting for reception in the morning.

07 — Bilbao

Physiotherapy clinic

Appointments booked in Spanish or Basque, cancellations offered to the next patient, and the clinic's own questions and answers kept in the knowledge base.

08 — Madrid

Veterinary clinic

Emergency calls sent straight to the vet on duty, routine appointments booked, and reminders sent on WhatsApp.

Outbound calls

What are the rules for AI sales calls in Spain?

You are responsible for following them. Spain's telecoms law gives people the right not to receive unwanted commercial calls, and the data-protection agency (AEPD) expects you either to hold consent or to have weighed a legitimate interest — and to check the advertising exclusion lists, such as the Lista Robinson, first.

What the official texts say, as read on 25 October 2026: the right not to receive unwanted commercial calls is in article 66.1.b of Ley 11/2022, the General Telecommunications Law. The AEPD's Circular 1/2023 (BOE, 28 June 2023) says that such calls can rest on consent or on a legitimate interest you have weighed beforehand; that commercial calls to randomly generated numbers need prior consent; and that the exclusion systems must be consulted first. Article 23 of Ley Orgánica 3/2018 (the LOPDGDD) is the rule on exclusion systems: anyone planning direct marketing must consult them, unless the person has consented to that sender. The Lista Robinson is run by Adigital.

The Circular also says to tell the person, at the start of the call, who you are, that the call is commercial and that they may object, and to treat any clear sign that they do not want such calls as an objection. It leaves automated calls (paragraph 66.1.a of the same article) outside its scope, and we could not verify how an AI voice agent is classified, so take advice and plan on the stricter view.

The product gives you tools: a do-not-contact list you keep, calling hours you set for each campaign on the called person's clock, an opening line you write, and a transcript of every call. It does not screen numbers against the Lista Robinson, and it does not collect or check consent. A separate resolution of 14 April 2026 (BOE, 16 April 2026) reserves the 400 number range for outbound commercial calls by the companies covered by Ley 10/2025; whether it applies to you, and whether your carrier offers that range, are questions for you and your adviser. We have not tested it. Answering your own inbound calls is a different matter from cold calling, and most businesses start there. Read the official text; not legal advice.

Customer service

Do I have to offer a person as well as the AI?

Not as a general rule for a small business. But Spain's customer-service law, Ley 10/2025, forbids automated answering as the only way to reach customer service and lets customers ask for a person; it covers certain sectors and larger companies.

Ley 10/2025 of 26 December 2025 (BOE, 27 December 2025) covers water, gas, electricity, passenger transport, postal, electronic communications and financial services, plus other companies selling mainly to consumers that, alone or in a group, have 250 or more employees, more than 50 million euros of turnover or more than 43 million euros of balance sheet. Article 8 forbids answering machines or similar means as the only channel and says a chatbot or similar tool must let the customer ask for a person. Companies have twelve months from the law's entry into force to adapt. If that is you, set a transfer to a person (it works on Plivo and Telnyx numbers) and take advice. Read the official text, as read on 25 October 2026; not legal advice.

WhatsApp

Does it work on WhatsApp for customers in Spain?

Yes. The same agent answers on WhatsApp, website chat and the phone, with chat replies in 37 languages (Spanish and English among them) and a shared inbox where your team can take over.

WhatsApp is how many customers in Spain prefer to deal with a clinic, a salon or a repair shop. Marketing messages need care: article 21 of Ley 34/2002 (the LSSI-CE) forbids advertising by email or equivalent electronic means unless the person asked for it or authorised it, with a narrow exception for your own existing customers and similar products, provided every message offers a simple, free way to opt out. Whether your messages count is a question for your adviser. See the WhatsApp Business API and the WhatsApp AI agent. Read the official text, as read on 25 October 2026; not legal advice.

Agencies

Can a Spanish agency resell it under its own brand?

Yes. White label comes with every paid plan: your brand, your domain, your email sender, your sign-in page and your own prices.

Your clients pay you through your own card checkout, buy your plans and set up automatic top-up. You build their receptionists; they see only your brand. See white label for agencies.

Billing

Do you bill in euros?

No. International workspaces, Spain included, are billed in US dollars by card. Checkout runs through a merchant of record that handles sales tax and VAT, and your bank converts the charge. Prices are on the pricing page.
