Automated AI Phone Agent with RetellAI and GPT-4o
detail.loadingPreview
Supercharge your customer interactions with an AI-powered phone agent. This n8n workflow leverages RetellAI for voice capabilities and GPT-4o for intelligent conversation analysis and data extraction.
About This Workflow
This n8n workflow orchestrates an advanced AI phone agent solution, designed to streamline communication and extract valuable insights from customer calls. It begins by filtering incoming webhook events from RetellAI, focusing on call completion and analysis. The conversation data is then processed by OpenAI's GPT-4o model to extract structured information such as contact details, summaries, and event-related dates. This extracted data is used to enrich Qdrant vector stores for knowledge retrieval and then further processed by another GPT-4o model within a Retrieval Augmented Generation (RAG) context. Finally, the system can automatically create calendar events in Google Calendar and send detailed summaries via Telegram, ensuring no important follow-up is missed.
Key Features
- Intelligent Call Analysis: Utilizes GPT-4o to understand and summarize call content.
- Automated Data Extraction: Extracts key information like names, emails, and event details from conversations.
- Seamless Integration: Connects with RetellAI for voice, OpenAI for AI processing, Qdrant for knowledge base, and Google Calendar/Telegram for action.
- Contextual Awareness: Employs RAG to retrieve relevant company data for more informed interactions.
- Actionable Outputs: Automatically schedules events and sends notifications based on call outcomes.
How To Use
- RetellAI Webhook Setup: Configure RetellAI to send webhook events (e.g.,
call_ended,call_analyzed) to the n8n webhook endpoint. - Filter Node Configuration: Set up the 'Filter' node to trigger the workflow when specific events are received from RetellAI.
- OpenAI Integration: Connect your OpenAI API credentials and configure the 'OpenAI Chat Model' nodes to process conversation data and extract structured information.
- Qdrant Vector Store Setup: Configure the 'Retrive Qdrant Vector Store' and 'Embeddings OpenAI2' nodes with your Qdrant collection and OpenAI API credentials for knowledge retrieval.
- RAG Node Configuration: Set up the 'RAG' node to act as a tool for the AI model, enabling it to access your company's knowledge base.
- Output Parsing: Utilize the 'Structured Output Parser' to define the schema for the extracted data from the AI model.
- Action Node Configuration: Connect the 'Google Calendar' and 'Telegram' nodes, mapping the extracted data from the AI model to the respective fields for event creation and notifications. Ensure your Telegram
CHAT_IDand Google Calendar email are correctly set.
