Under the hood
An AI voice agent that holds a real sales conversation.
An AI voice agent is not a voice reading a script. At Revox, it understands what the person says, qualifies them, handles an objection and books a meeting in the right calendar. You describe it, it trains with you, then it makes your outbound calls.
What you are comparing
Every phone AI can talk. Few can sell.
Three reasons an AI voice assistant ends up on the shelf after the first test.
It recites, it does not listen
The person asks a question outside the script, the agent starts over. They say they are driving, it keeps going. After the second call like that, your team unplugs it.
It costs weeks before the first call
A decision tree to draw, intents to label, an integration to get coded. The project starts with a project manager and ends with a change order. Meanwhile, your leads wait.
It is fast, but it calls too late
The voice answers instantly, and the lead who filled in your form on Monday gets called on Thursday, once someone remembered to export the list. Over 90 days of data, the speed of the voice changes nothing in the result. The delay between the signal and the call does.
How it is built
You describe it, you test it, it calls.
You say what the agent needs to get. What makes people pick up, hang up or accept a meeting, it already knows.
Your AI voice agent, written in 5 minutes
You say in a few sentences what the agent needs to get on the phone: a meeting, an answer, a document. An assistant writes the agent for you. You pick its voice from more than 30, and you create as many agents as you want.
You play the prospect, it corrects itself
You call it and play the difficult customer: an objection, an off-topic question, a "call me back later". You tell it what is wrong, it corrects itself. A few tries later, it is ready.
It calls on the signal, connected to your CRM
A form filled in, an abandoned sign-up, an enquiry on a listing: the agent calls as soon as the signal comes in, within the minute when your tool is connected. It tries up to 5 times with spaced attempts, recognises voicemail, and transfers to a human on the number of your choice. Every call is recorded, transcribed and pushed back into HubSpot, Zoho or your tool.
90 days of data
The pick-up rate does not move. The result does.
Around 40% pick-up everywhere. A voice AI agent is judged on what happens once the person is on the line, and on when it calls them.

Questions before testing
What you want to know before testing.
Factual answers, verifiable by listening to a call.
A program that makes a call, listens to the person, understands what they say and answers in real time, with a goal to reach: book a meeting, get an answer, qualify a need. At Revox, it stays within the frame you gave it and knows what to do with an objection or an unexpected question. It is not a press-one phone menu, it is a conversation.
Yes. Since 2 August 2026, an AI on the phone must be able to say it is one, and the agent says so. It never impersonates anyone and keeps no voiceprint. Since 11 August, individuals who never asked you for anything are no longer called: calling back your customers, people who left their number with you or professionals on their business line remains allowed.
The agent transfers the call to the number of your choice, it is built in, nothing to add. On a question its frame does not cover, it says so and offers to pass it on rather than making something up. And if asked to stop calling, it is applied immediately.
HubSpot, Zoho and the main tools on the market are connected: contacts come from your CRM and the result of every call goes back into it. For another tool, tell us. To start without connecting anything, a simple contact file is enough. Data is hosted in France and Europe, isolated in your account, never used to train a model.
Because it calls whoever you give it, whenever you give it. Over 90 days, the same technology gets 70% positive conversations when the person raised their hand less than 48 hours ago, and 14% on a cold list or on a database asleep since 2021. Before comparing voices, measure in your own business the time that passes between a form filled in and the first call. That delay is what the agent has to shorten.
Five minutes to write it: you describe it to an assistant that drafts the agent, then you call it to hear it. Twenty-four hours for a full campaign with your list.
More than thirty voices are available. That choice matters more than it seems: the tone for chasing a quote is not the tone for booking a medical appointment.
It sends a text message when useful, for instance a link to resume an abandoned form, it transfers to a human, and it pushes the call outcome back into your tool.
Never lose
