Distributed Ledger Technology (DLT) is a digital method that allows users and systems to record transactions related to their assets in multiple locations, providing better security, transparency, and trust amongst parties. In India, the Telecom Regulatory Authority of India (TRAI) requires any domestic enterprise sending Application 2 Phone (A2P) SMS through domestic connections to pre-register with DLT. To comply with this regulation, enterprises must register their Principal Entity, Headers, Templates, and provide consent on a listed DLT system. Vonage provides an API account and SDKs that can be used to send DLT-compliant SMS messages, requiring the addition of two parameters (entity-id and content-id) to every request or SMPP request. Enterprises can use Vonage's temporary solution to let Vonage manage DLT for them, but it is recommended to update their project and use the new API parameters to comply with the regulation. A webhook can be used to receive SMS delivery receipts and verify if an SMS message was sent successfully.
