AI voice agent that answers your business calls

An AI voice agent answers your phone in natural speech, books appointments, qualifies new leads and hands the caller to your team when a person is needed. STOLOSDIGITAL builds it on your existing number, connects it to your calendar and CRM, and hosts it in the EU.

What is included

What the voice agent does on each call

We set the agent up for the calls your business receives most often. Everything else goes to your team, with the context already written down.

Answers every call

The agent picks up on your existing number during the hours you choose, including evenings, weekends and busy periods.

Books appointments

It checks free slots in your calendar or booking system, offers times and confirms the appointment while the caller is on the line.

Qualifies leads

It asks the questions your sales team would ask, records the answers and marks which callers are ready for a quote.

Hands off to a person

When a caller asks for a human, or the request falls outside the agent's rules, it transfers the call or books a callback.

Logs every call

A transcript and short summary go to your CRM or inbox after each call, so nobody has to type up notes.

Reminders and follow-ups

Optional outbound calls for appointment reminders or follow-ups on enquiries, within the rules you set.

How we work

From your call list to a live voice agent

01
Free 30-minute call
We go through the calls you receive today: the most common requests, your booking rules and when a person must take over.
02
Written plan within 48 hours
The call flow, the systems the agent connects to, the timeline and a fixed price, all in writing before any build starts.
03
Build and test
We write the call script, connect your calendar and CRM, and test the agent on realistic calls until it handles them correctly.
04
Supervised launch
The agent goes live on part of your call volume first. Your team reviews the transcripts every week and we adjust the rules.

Timeline

A voice agent for one type of call, such as bookings or opening-hour questions, is usually live within a few weeks of the plan being agreed. Agents that connect to several systems or cover many call types are delivered in phases, and you hear the agent on test calls every week.

Pricing approach

We give a fixed quote after a free call. The build has a fixed price per phase. Running costs for telephony and voice models depend on how many minutes the agent handles, so the plan includes an estimate based on your current call volume.

EU-based team

Why choose an EU team for your voice agent

We are an EU company, stolosofficial s. r. o., registered in Bratislava, Slovakia. Your contract and your data processing terms sit under EU law.

Call recordings, phone numbers and transcripts are personal data under the GDPR. We can host recordings, transcripts and logs in EU regions, in accounts you own, and you set how long they are kept.

The EU AI Act requires that people are told when they are interacting with an AI system. Our voice agents say they are AI at the start of every call, and the call script is documented so your team knows exactly what the agent says.

Our guarantee

If it does not handle the calls we agreed, the pilot is free.

We start with a pilot on your real calls. Before it starts, we agree in writing which calls the agent must answer and which it must book. If it does not do that during the pilot, you do not pay for the pilot.

What we need from you: Access to your phone line and booking calendar, the answers to your common questions, and a short review of the call log each week.

AI voice agent questions

What is an AI voice agent?

An AI voice agent is software that answers phone calls in natural speech. It understands what the caller asks, answers from your own information, books appointments, captures lead details and passes the call to a person when needed.

Can the voice agent use our existing phone number?

Usually yes. Calls are forwarded from your current number to the agent, either all the time or only when your team does not pick up. We confirm the setup for your phone provider on the first call.

What happens when a caller wants to talk to a person?

The agent transfers the call to the number you choose, or takes a message and books a callback if nobody is available. You decide which topics always go to a person.

Will callers know they are talking to an AI?

Yes. The agent says it is an AI assistant at the start of the call. The EU AI Act requires that people are told when they interact with an AI system, and being open about it also builds trust with callers.

Which languages can the voice agent speak?

We can build the agent in English, German, Greek and other European languages that current voice models support. We test the agent in each language you need before launch and set it to switch to a person if it cannot understand the caller.

How much does an AI voice agent cost?

You get a fixed quote after a free call. The written plan states the price for the build and an estimate of the running costs per call minute, which depend on your call volume.

Where are call recordings and transcripts stored?

We can store recordings, transcripts and logs in EU regions, in accounts you own. You decide how long they are kept, and only the people and systems that need them have access.
