About this gig
I will build a professional AI voice calling agent using Vapi AI, Retell AI, and n8n. The agent can handle inbound & outbound calls, automate conversations, and deliver a natural human-like voice experience. I can train your AI voice using your FAQs, product information, pricing, and documentation to provide accurate, brand-specific answers.
Your AI agent can book appointments, transfer calls to a human agent, and work as a 24/7 support system. I also integrate it with your website, CRM (GoHighLevel, WordPress), and other platforms.
For tracking, I can connect the agent with Google Sheets to store call logs and results, and create a Looker Studio dashboard for call analytics, performance, and conversion insights.
