What is A2P (Application-to-Person) calls?

A2P calls are phone calls originated by an application or software rather than by a person dialling, and delivered to a person, as in reminders, alerts, voice broadcasts and AI voice agent calls.

Also called: A2P call, application to person calls, A2P voice

The term comes from telecom, where traffic is classed as person-to-person (P2P) or application-to-person (A2P). The better-known A2P in India is business SMS, which runs on DLT-registered senders and templates. Voice follows the same logic: a business using software to place calls to customers is sending A2P traffic, which carriers and TRAI treat differently from an ordinary consumer call, and which needs a properly registered calling line.

Why it matters

For a business, A2P status is the reason a normal mobile SIM is the wrong way to run automated calling. Using a registered business number reduces the chance that calls are blocked or marked as spam, and it keeps you on the right side of TRAI's commercial communication rules. Outpero's dedicated +91 number, at ₹649 a month with one channel included, covers compliance and carrier fees, and bulk campaigns screen against DND.
