# Compliance

> Calling rules, consent, and your Do-Not-Call registry.

Compliance settings apply platform-wide across every number and every outbound campaign on your account.

## Calling window

TRAI norms limit unsolicited calls to 9am–9pm, Monday–Saturday. With **Enforce calling window** on, Vistrow Voice blocks outbound dials automatically outside the start/end time and allowed days you configure, evaluated in the callee's local timezone.

## Consent, recording & retention

| Setting                    | What it does                                                                                            |
| -------------------------- | ------------------------------------------------------------------------------------------------------- |
| **Honor Do-Not-Call list** | Never dials a number on your DNC registry.                                                              |
| **Require spoken consent** | The agent opens every call with a consent line and logs the caller's reply.                             |
| **Record calls**           | Stores call audio alongside transcripts.                                                                |
| **Data retention (days)**  | Transcripts and recordings older than this are purged automatically. `0` keeps everything indefinitely. |

<Tip>
  If you're subject to India's DPDP Act or a similar data-minimization requirement, set a real retention window here rather than leaving it at `0` — see your [Privacy Policy](https://vistrowvoice.com/privacy) for how Vistrow Voice itself handles retention and deletion requests.

## Do-Not-Call registry

Upload or paste numbers that should never be dialed. Every outbound dial — from a campaign or a one-off test call — is scrubbed against this list first.
