AI Phone Agent with RetellAI

# Create your first AI Phone Agent

Build, test, deploy, and monitor AI phone agents. Retell is a comprehensive platform for building, testing, deploying, and monitoring reliable AI phone agents.
Conversation flow agent allows you to create multiple nodes to handle different scenarios in the conversation. It provides more fine-grained control over the conversation flow compared to single / multi prompt agent, which unlocks the ability to handle more complex scenarios.

This Workflow simulates an AI-powered phone agent with two main functions:

📅 Appointment Booking – It can schedule appointments directly into Google Calendar.

🧠 RAG-based Information Retrieval – It provides answers using a Retrieval-Augmented Generation (RAG) system. For example, it can respond to questions such as store opening hours, return policies, or product details.

The guide also explains how to purchase a dedicated phone number (with a +1 prefix) and link it to the AI agent. This setup is cost-effective, as it uses a free $10 credit to operate without additional charges in the beginning.
