Hey guys I am working on a npm package that allows you to build with mutiple voice AI providers like Vapi and Retell or even your own custom provider. It's an SDK that allows you to use any provider without vender lock in so if you want to switch to using another one later you don't have to change your whole codebase I will add more in the future you can check it out use it contribute to it if you want and let me know what you think https://www.npmjs.com/package/@keyman500/voice-ai-sdk
