Unlike standard browser-based voice bots, this AI agent connects directly to the telephone network (PSTN) via SIP, allowing it to handle real inbound and outbound calls just like a human receptionist. If you're tired of paying high per-minute markups to managed services like Vapi, Bland AI, or Retell, this tutorial shows you how to own the infrastructure. You control: - The LLM - The call logic - The telephony routing - The deployment - The costs And once deployed to the cloud, your AI phone agent truly never sleeps.
