A2P call

An A2P (application-to-person) call is a voice call that an application, software or automated platform starts, with no person dialling it. TRAI's amendment of 18 September 2026 names autodialled calls, robo-calls and pre-recorded or artificial voices, so an AI voice agent's outbound calls are A2P calls and must be declared to the telecom operator in advance.

How it works on Indian calls

The A2P category comes from the Third Amendment to TRAI's Telecom Commercial Communications Customer Preference Regulations (TCCCPR), 2018, announced by PIB on 18 September 2026 (release ID 2311989). Three things follow for any business that calls with software:

  • Declare before the first call. Every entity using A2P calls tells its telecom operator in advance, and lists the caller IDs (CLIs) it will call from.
  • Undeclared calls count as spam. An A2P call made without that declaration is treated as unsolicited commercial communication (UCC), which brings in spam flags and complaint action.
  • A charge between operators. Operators may charge each other up to ₹0.05 a minute to carry A2P calls. Calls from the number series set aside for regulated commercial calls are exempt.

Say a lender's AI agent calls a list of borrowers about EMIs due this week. Every one of those calls is an A2P call, so the agent's caller IDs have to be on the operator's record before the campaign starts.

Why it matters

The amendment doesn't ban AI calls. It makes them visible to operators, and it ties undeclared automated calling to the spam rules. The PIB release doesn't give start dates, so check the gazette text before you plan a launch around one. It also doesn't require an A2P call to say on the line that it's an AI. The duty it creates is the declaration to the operator.

How Kallix handles it

Kallix declares automated calling to the operator for the numbers it provides through Vobiz, our telephony partner, so you don't file that declaration yourself. Your business keeps its own DLT registration as the sender, and the consent of the people it calls. Every Kallix agent also says it's an AI assistant in its first line and offers a person on request. That's our policy, not a TRAI rule.

Yes. TRAI's 2026 amendment covers calls that software starts without a person dialling, and it names artificial voices. Outbound calls from an AI voice agent fit that, so they're declared to the operator, with their caller IDs, before the first call.

TRAI treats them as unsolicited commercial communication, in other words spam. Spam flags and complaints can then lead to graded action against the sender, from a fresh KYC check to a bar on outgoing calls or disconnection.

Kallix does, for the numbers it provides through Vobiz, so you don't file the declaration yourself. Your business still registers on DLT as the sender and holds the consent of the people it calls.
