Why Call0
More than an AI answering machine.
Call0 does more than pick up. The assistant clarifies the request, hands over to your team when a person is needed, and answers with the same knowledge on WhatsApp, by email and in the website chat.

- Enter your website, and Call0 builds the assistant from it. 15 test minutes in the browser, without a credit card or sales call.
- Several lines from the first plan
- Launch includes 3 concurrent calls, 700 minutes and 1 phone number. Nobody hears a busy tone when two customers call at once.
- A person takes over when it matters
- Handover to your team with a queue, hold music, opening hours and a callback list. The caller is never left hanging.
- Phone, WhatsApp, email and chat in one account
- One knowledge base for every channel. You maintain it once, and every assistant answers the same way.
- Over 500 integrations
- Appointments land in your calendar, requests in your CRM or ticketing system, without manual copying.
- Set up in conversation

FAQ
Frequently asked questions.
Your exact setup depends on telephony, workflows and the integrations you want to use.
Can Call0 book into our reservation system?
Through a connected calendar or by webhook, yes. Without a connection, Call0 captures the reservation in full and your team confirms it.
What happens when we are fully booked?
Call0 only confirms what is confirmed. Without an availability check, Call0 takes the request and says honestly that you will get back to the guest to confirm.
Do I have to change my phone number?
No. You can forward your existing number—permanently, only when the line is busy, or only outside opening hours. Alternatively, you get a Call0 number of your own.
Do callers notice that they are talking to an AI?
Yes, Call0 introduces itself as a digital assistant at the start of the call. The voice sounds natural and the conversation is short and clear—with no hold queue.
