The hardest part of a voice agent isn't the AI. It's the silence.
Notes from building a bilingual phone receptionist for a Miami brokerage: when is a caller done talking, what did they actually say, and why the answer to "buy or lease?" kept vanishing.
My AI told a caller it had texted them. It hadn't.
Notes on SMS consent for AI agents: a state machine, a single gate, and a rule I learned the hard way: never trust the model to report what it did.
A refresh token that dies when you use it: what I learned from QuickBooks OAuth
Notes on token rotation, a duplicate-invoice guard, and keeping sandbox and production apart, from a client project that went live in a single day.
