## Overview

Vanessa is an outbound voice-acquisitions agent. The documented workflow starts with leads in Google Sheets, has n8n initiate and monitor calls, qualifies sellers through a conversational voice agent, and transfers qualified sellers to a human. After the call, transcript analysis produces a structured summary and classification that n8n logs back to Sheets. The repository tree contains a workflow JSON and named call-related entries, but no source excerpts; links below follow the README’s documented relationships rather than inferred implementation details.

Main entry points: [`Lead Aqu_Voice_Agent.json`](https://github.com/omichougule/voice-ai-acquisitions-agent/blob/main/Lead%20Aqu_Voice_Agent.json) (n8n orchestration), [`Alex`](https://github.com/omichougule/voice-ai-acquisitions-agent/blob/main/Alex) (Vanessa voice agent), [`Lead List.xlsx`](https://github.com/omichougule/voice-ai-acquisitions-agent/blob/main/Lead%20List.xlsx) (Lead list and CRM), [`Transfer_Call`](https://github.com/omichougule/voice-ai-acquisitions-agent/blob/main/Transfer_Call) (Qualified call transfer)
