Overview

This system transforms how businesses handle inbound calls by using AI to act as a 24/7 voice receptionist. It captures leads, answers questions, books appointments, and syncs with calendars — without any human intervention.

Built entirely with no code, it combines Retell AI (voice agent), Cal.com (scheduling), and Google Calendar (organization). The agent listens, responds naturally, and executes real booking actions through connected APIs.

How it works

  1. A customer calls your business number.
  2. The AI answers instantly, confirms details like name, service type, and preferred time.
  3. It checks your real-time availability via Cal.com and books the slot in Google Calendar.
  4. If no slots are available, it offers alternatives automatically.

The entire build takes less than 30 minutes using no-code tools. Once deployed, it acts as a tireless digital employee.
