Voice Agent for Booking

Realtime voice bot that handles lead qualification and appointment scheduling — doubling booking conversion rates while eliminating repetitive calls.

Project Overview

The client's sales team was overwhelmed with inbound calls — most were repetitive scheduling requests that consumed hours daily. They needed automation without sacrificing the human-like interaction that builds trust.

I built a realtime voice agent that handles the entire booking flow: greeting, qualification questions, availability check, appointment confirmation, and follow-up — all through natural voice conversation powered by LLMs.

The Challenge & Solution

Challenge

  • 70% of inbound calls were repetitive booking requests
  • Sales team spending 4+ hours/day on scheduling
  • Missed calls during peak hours losing potential leads
  • Existing IVR system felt robotic and drove callers away

Solution

  • Natural voice AI that handles full booking conversation
  • LLM-powered routing for complex queries to human agents
  • Calendar API integration for real-time availability
  • Webhook automation for confirmations and reminders
