TRAI, DND & DLT Compliance for AI Calling in India: A 2026 Guide

Before you run any outbound AI calling campaign in India, it's worth understanding the rules that govern commercial communication — chiefly TRAI's DND framework and the DLT system. This is a plain-language overview to help you ask the right questions; it is not legal advice, and you should confirm your specific obligations with current TRAI guidance and your own compliance team.

Who sets the rules: TRAI

The Telecom Regulatory Authority of India (TRAI) regulates commercial communications, including unsolicited commercial calls and messages. Its regulations aim to protect consumers from spam and give them control over what commercial communication they receive. Any business making commercial calls at scale — human or AI — operates within this framework.

DND: the consumer's preference

DND (Do Not Disturb), more formally the customer-preference registration system, lets consumers opt out of some or all categories of commercial communication. In practice, this means:

• Consumers can register their preferences about which commercial calls and messages they're willing to receive.
• Businesses making commercial calls are expected to respect those registered preferences.
• Consent matters: reaching customers who have opted in, or with whom you have an existing relationship, is fundamentally different from cold-calling registered numbers.

The core principle is simple: respect the customer's stated preference. An AI agent should be pointed at contacts you're permitted to call, just as a human team should be.

DLT: the registration layer

The DLT (Distributed Ledger Technology) system was introduced to bring accountability to commercial communication. It involves registration of entities, and in the messaging context, of senders, headers, and templates, so commercial communication is traceable to a registered party. If your programme includes commercial messaging alongside calling, DLT registration is part of the picture.

The practical takeaway: commercial communication in India is designed to be traceable and consent-driven, not anonymous mass outreach.

What this means for AI calling specifically

AI doesn't change the rules — it just makes calls faster. So the same obligations apply:

• Call people you're permitted to call. Use consented lists and respect DND preferences.
• Be transparent. Don't misrepresent who is calling or why.
• Keep records. Being able to show what was said and to whom is valuable if a question ever arises.
• Respect calling norms. Reasonable calling hours and conduct still apply.
