Hey everyone 👋 I’m building a real estate voice AI agent using Vapi and I want to go deeper into how Vapi works under the hood. I’ve gone through the docs and tried a few basic calls, but I’d like to understand it at a more advanced level. Does anyone know of good tutorials, walkthroughs, or even open-source projects that explain: How to structure real-time branching conversations cleanly Make it sound super realistic and also try closing the leads with the AI agent instead of a human How to handle interruptions/objections smoothly Any recommendations would be super helpful, happy to dig into technical content or examples if someone can point me in the right direction 🙏
