# How does SMSGatewayCenter ensure that transactional voice messages via OBD are delivered reliably, even with DND restrictions?

**SMSGatewayCenter**’s **[Outbound Dialing (OBD) service](https://www.smsgatewaycenter.com/voice-obd-calls-automated/)** is designed to deliver transactional voice messages reliably, ensuring they reach your customers even with Do Not Disturb (DND) restrictions in place. Here’s how:

- **Bypass DND Restrictions**:
  - Transactional messages, such as OTPs, order confirmations, or payment reminders, are exempt from DND restrictions.
  - SMSGatewayCenter ensures these messages are delivered 24/7, regardless of the recipient’s DND settings.
- **Robust Infrastructure**:
  - Powered by a high-speed, scalable cloud setup with a 10G network for fast and secure delivery.
  - Automatic redial options (e.g., up to 2 retries with a 5-minute interval) ensure messages reach recipients who don’t answer initially.
- **Examples of Transactional Messages**:
  - OTP: “Your OTP for login is 1234. It expires in 10 minutes.”
  - Order Alert: “Hi, your order #12345 has been shipped and will arrive by May 17, 2025, at 3:00 PM IST.”
  - Payment Reminder: “Your payment of INR 500 is due on May 18, 2025. Pay now to avoid late fees.”
- **Monitoring and Reporting**:
  - Use SMSGatewayCenter’s web interface to track delivery status in real-time (e.g., answered, busy, failed).
  - Fetch detailed reports via APIs to integrate with your systems.

**SMSGatewayCenter**’s OBD service ensures your transactional voice messages are delivered promptly and reliably, keeping your customers informed. For more details, contact our support team.
