Seen from a corridor through an open doorway into an empty staff canteen in late-afternoon sun: a woman in a headset stands at the far end by the window wall with her back half turned, while a man in a light shirt sits closer to the camera at the long table with his hands folded, a mug and a face-down mobile phone in front of him
Call flow

One customer call, beat by beat. Seven links that can break.

11 Sept 2026

OpenAI has now put a price on the voice layer alone: $0.05 a minute for the part that listens and speaks. Which makes it worth walking one perfectly ordinary call through link by link, and asking who actually owns each of them.

Customer experience

Customers don't hate the bot. They hate calling twice.

“Our customers want to talk to a person” is the most common objection to voice agents. It deserves to be taken seriously — but it measures something other than what it thinks.
