Architectural Approach
Challenge
Enterprises experienced delays in critical OTP verification messages and struggled with manual national consent registry synchronization.
Solution
We engineered a high-availability SMS gateway connected directly to carrier SMPP backbones with automated consent filtering and real-time DLR telemetry.
Results
- OTP and alert tracking with carrier delivery reports
- Queue-based processing for high-volume sends
- Enterprise integration via REST API
- Automated consent and opt-out synchronization
