Voice Settings (Per-Campaign)
Per-campaign caller-ID audio, voice selection, and dispatch defaults.
Last updated 05/24/26
What this surface does
The Voice Settings surface (migration 192) holds per-campaign voice configuration — caller-ID audio (migration 195), default text-to-speech voice, machine-detection behavior, retry policy, and quiet-hours overrides.
When to use it
- New campaign onboarding — set the caller-ID audio + preferred TTS voice before the first broadcast.
- A customer requests a different voice or detection behavior.
- Compliance — recording the caller-ID audio is a prerequisite for some carriers.
Key gotchas
- Caller-ID audio is per campaign, not per phone number. A campaign with multiple numbers shares the same caller-ID audio.
- Changing TTS voice mid-campaign means previously-rendered audio is regenerated on next send — small cost + delay.
- Quiet-hours overrides do not bypass state-level legal rules (see SMS State Rules — voice has its own analogous limits).
