 In this example, we build both inbound and outbound calling agents using Twilio, Stream, and RAG backends (Gemini FileSearch or Turbopuffer). The inbound agent answers calls and uses a knowledge base to provide product information. The outbound agent can make calls programmatically—like booking a restaurant reservation. This demonstrates how to connect AI voice agents to the phone network with real-time knowledge retrieval.
