CallBooker

CallBooker uses AI voice agents to call new leads within seconds, handle objections, qualify and book meetings straight into Google Calendar or Calendly. Agents run on ElevenLabs voices in 33 languages through your own Twilio number, with a free tier of 10 talk minutes and paid plans starting at $39 per month.

CallBooker is an AI appointment setter built around a simple observation: leads go cold while they wait for a callback. The product places an AI voice call to a new lead within seconds of it arriving, introduces itself, answers questions about the offer, works through common objections and, when the interest is real, books a meeting live on the call into Google Calendar or Calendly. Conversations run on ElevenLabs voices across 33 languages, and the agent is instructed to disclose that it is an AI assistant and to honour do-not-call requests. The tool is aimed at teams that live on booked calls: SaaS and B2B demo requests, agencies handling several clients, real estate agents racing other agents to a buyer, home services and solar quoting site visits, and insurance or finance teams qualifying quote requests. Setup is described as roughly 15 minutes, with no code: connect a Twilio account, attach your own phone number, link a calendar, describe the business or feed the agent a knowledge base, then test by calling yourself. In day to day use, leads arrive from a website form, a CRM, Zapier or an uploaded list, and campaigns let the agent work through a list with many calls running at once. Voicemail detection hangs up rather than billing you for a machine, and results come back with a transcript and summary. Interested leads who did not book land in a follow-up list with the agent's notes. Higher tiers add qualify-and-report mode, confirmation and no-show rebooking calls, recordings kept up to a year, and an API with webhooks. An MCP server lets Claude or Cursor manage leads and calls. Against alternatives, CallBooker sits between hiring a human setter and doing nothing. Its own comparison puts a full-time setter at roughly $4,500 a month versus $105 for the Growth plan, though that figure excludes Twilio call charges, which are billed to your own account at Twilio's rates.
