Response

Successful Response

Config response for an agent, augmented with source metadata.

source is "saved" when the agent references a saved config via Agent.voice_config_id, or "inline" when using its own 1:1 row. saved_config_id is the id of the linked saved config, if any. has_inline_fallback reports whether an agent-owned inline row exists; the UI uses it to know whether unlinking is safe (the agent falls back to its preserved inline config) or would leave the agent with no voice config.

first_speaking_config

FirstSpeakingConfig · object | null

Config for the AI's opening turn (no user input yet).

Lives inside ChannelConfig — first-speaking is per-channel.

Mode-agnostic fields:

first_speaker: "agent" opens the call with the rendered message; "user" skips the greeting (caller speaks first). Non-voice channels treat the inbound user message as the "user" opener and ignore this field at runtime.

Greeting source (only applies when first_speaker="agent"):

static mode: text is required and emitted verbatim (templated via the shared {{var}} engine, src.shared.templating.render).
dynamic mode: instructions are sent to the model router with the agent persona to render an opening line (instructions are templated). When omitted/empty, instructions falls back to DEFAULT_DYNAMIC_FIRST_SPEAKING_INSTRUCTIONS so operators who just want a generic friendly opener don't have to author copy.

Voice-only fields (ignored on non-audio channels):

interruptible: whether the caller can barge in mid-greeting.
ai_disclosure_text: regulatory disclosure (e.g. CA SB 1001), played as an uninterruptible TTS frame BEFORE the greeting. Disclosure plays even when first_speaker="user" because the regulation requires the disclosure regardless of who speaks first.
