Why CallStack.tech?
I spent months learning voice AI by piecing together scattered blog posts, incomplete docs, and outdated tutorials. Every implementation had edge cases the tutorials never mentioned. Every integration broke in production.
This site is what I wish existed when I started. Real code. Real challenges. Real solutions. No fluff, no "hello world" examples that fall apart under load.
I'm documenting the production lessons most tutorials skip, because that's where the real learning happens.
