VoiceConfig

Per-agent voice-agent settings shipped to the voice runtime at call start.

null/absent means "inherit the deployment default" — the UI should render unset fields as such, not as empty values. The agent-side mirror of this contract is RuntimeOverrides in backend_client.py; if the two ever drift, that file is the truth.
