Agentic Sales Call Center

A voice-AI agent that qualifies leads over the phone, end to end.

Agentic Sales Call Center
AI Automation & Voice AI
Architecture & Overview

A voice-AI lead-qualification system that pulls numbers from a Google Sheet, places outbound calls, and holds a human-like conversation. On genuine interest or a callback request, it fires WhatsApp confirmations to company and client, books a calendar slot, and logs every attempt to a tracking sheet.

The Problem

Manual outbound lead qualification is labor-intensive, has high latency, and often fails to log call notes or schedule immediate callbacks.

The Approach & Implementation

Integrated Vapi Voice AI with n8n workflow automation, Google Sheets API for contact queues, Twilio WhatsApp API for instant messaging, and Google Calendar API for automated booking.

Measurable Outcome

Automated end-to-end outbound calling with sub-second voice latency, instant calendar booking, and 100% automated CRM record synchronization.
