How a call flows
- The call arrives and enters a Journey IVR flow.
- On the chosen branch, the Transfer call to AI agent element hands the call to your published agent.
- The agent listens, reasons and speaks — repeating until the goal is met, the caller asks for a person or the session ends.
- Control returns to the IVR with the reason the session ended, so you can route the next step.
