Answers to the most common questions about Call0.
What does the assistant sound like?
Natural — like a human. Call0 uses the best AI voices available, and most callers don't notice they're talking to an AI. Get the test call above and hear for yourself.
What happens with complex questions?
You set the rules: for topics the assistant shouldn't handle, it forwards the call to you or your team — or takes a clean note for your callback.
Do I need a new phone number?
No. Simply forward your existing number to Call0 — or get a new number from us. Both take just a few minutes to set up.

Yes. Call0 operates in compliance with GDPR, and you can sign the data processing agreement (DPA) directly online.
