AI Voice Receptionist for Missed Calls n8n, VAPI/ElevenLabs, Auto-Booking

We're a small service business losing leads to missed calls during busy hours and after closing. We want an AI voice agent that picks up or calls back automatically, sounds natural (not robotic), answers basic questions about our services, pricing range, and hours, and books the caller straight into our calendar if they want an appointment. If the AI can't resolve the call, it should take a message and text us a summary immediately so we can follow up ourselves. What we need: - AI voice agent connected to our business phone number - Natural-sounding conversation flow, not a rigid IVR menu - Calendar booking built into the call itself - Instant SMS summary to us after every call, resolved or not - Easy way for us to update the script/FAQ answers later without a developer Deliverables: - Working voice AI workflow (n8n + VAPI or ElevenLabs Conversational AI) - Twilio number connected and tested with real calls - Calendar integration (Google Calendar or Calendly) - SMS notification flow - Short handover walkthrough video
