We shipped an inbound voice agent on the Prototype tier. Calls in, qualifies, books a slot, transfers to human if anything is unclear.
What worked: STT latency is fine in 2026, calendar integration is trivial, and the model is good enough at small talk.
What did not: long pauses still feel robotic, and any number with an accent the model has not seen confuses the booking flow. Handoff to a human number is non-negotiable.
