# What steps should I take to ensure compliance with regulations when using SMSGatewayCenter’s Bulk Voice Call service for promotional messages?

Using SMSGatewayCenter’s [Bulk Voice Call service](https://www.smsgatewaycenter.com/voice-obd-calls-automated/) for promotional messages requires adherence to regulatory guidelines to ensure compliance and avoid penalties. Here’s how to stay compliant:

- **Obtain Opt-In Consent**:
  - Ensure all recipients have explicitly opted in to receive promotional messages, as required by WhatsApp and TRAI (Telecom Regulatory Authority of India) guidelines.
  - Use SMSGatewayCenter’s *Add Opt-In* page to manage your opt-in list and verify consent.
- **Target Non-DND Numbers**:
  - Promotional messages must only be sent to non-DND numbers to comply with regulations.
  - Filter your contact list to exclude DND numbers before launching a campaign.
- **Adhere to Time Restrictions**:
  - Send promotional messages only between 10:00 AM and 8:00 PM IST, as mandated for marketing communications.
  - Schedule campaigns accordingly (e.g., set for May 16, 2025, at 11:00 AM IST).
- **Provide Opt-Out Options**:
  - Include instructions for recipients to opt out (e.g., “Reply STOP to unsubscribe”).
  - Use SMSGatewayCenter’s *Manage Opt-In* page to mark numbers as opted out if requested.
- **Keep Messages Clear and Relevant**:
  - Avoid misleading or spam-like content in your voice messages.
  - Ensure the message provides value (e.g., “Get 20% off this weekend! Visit our store by May 18, 2025.”).
- **Document Compliance**:
  - Maintain records of opt-in confirmations and campaign details to demonstrate compliance if required.
