Frequently asked questions

CallBooker is an AI appointment setter: AI voice agents call your leads within seconds, handle objections, qualify them and book meetings straight onto your Google Calendar or Calendly, in 33 languages, through your own Twilio number.

No. Agents use ElevenLabs voices, among the most natural available, and you can pick one from the voice library to fit your brand. The best way to judge is to hear it: enter your number at the top of this page and our AI calls you in seconds.

Yes. CallBooker calls through your own Twilio account, so the numbers are yours and you pay Twilio’s rates directly. Setup walks you through connecting Twilio and getting a number.

You get a notification at 80% and 95%. When you run out, new calls stop and running campaigns pause; calls in progress finish normally and you’re never charged extra. Upgrade to continue right away, or wait for your minutes to refill at the start of your next billing period.

It depends on who you call and where. In the US, AI voice calls are treated as artificial-voice calls under the TCPA, which generally requires the person’s prior consent; the EU and UK have their own rules. CallBooker gives you the tools (your own numbers, honest AI disclosure, automatic do-not-call), and you agree to call only people you’re allowed to call. If in doubt, ask a lawyer about your use case.
