The Telecom Regulatory Authority of India (TRAI) has recently revised its guidelines regarding the use of URLs and callback numbers in bulk SMS campaigns.

According to the updated regulations, all the URLs and callback numbers used in your bulk SMS campaigns must be whitelisted with your DLT (Distributed Ledger Technology) operator.

This means that prior approval is required for using these links and numbers. If you are using TATA DLT, the following guide will walk you through the process of whitelisting your Call to Action (CTA) for your SMS campaigns.
