Answers to the most common questions about Call0.
What does the assistant sound like?
Listen to the available voices and test the agent yourself. Call0 clearly tells callers that they are speaking with an AI assistant.
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.
How does Call0 support GDPR requirements?
Call0 explains its data processing and provides an online DPA. Whether your use meets every GDPR requirement also depends on your configuration, legal basis and caller notices.
How fast can I get started?
Describe your business, choose a voice, and review the settings. No dedicated IT infrastructure is required.
