Voice over Internet Protocol (VoIP) has changed how businesses talk to customers all over the world. It’s cheaper, more flexible, and works well with new ways of talking to people.

There are some rules for VoIP in India, though. The Telecom Regulatory Authority of India (TRAI) and the Department of Telecommunications (DoT) have rules that companies must follow.

This guide tells you what’s legal and what’s not, as well as how to set up VoIP in India the right way.

What you can do with VoIP in India

You don’t need a telecom license to make IP-to-IP calls or app-to-app calls. This means that people who have the same app, like WhatsApp, Zoom, or Teams, can call each other.

Businesses can legally make international calls using licensed international long-distance (ILD) providers.

CRM, autodialer, and call center integration: Companies can use legal VoIP services to keep track of calls, recordings, and reports without breaking the law.

What You Can’t Do

Connecting PSTN and VoIP Without a License: In India, you can’t connect VoIP directly to landlines or mobile networks without a Unified License.

Grey Routes & SIM Boxes: Using SIM cards to turn VoIP calls into local GSM calls (toll bypass) is against the law and can get you in trouble.

Unlicensed Caller ID Masking: You have to show a valid number (CLI). Using fake or spoofed IDs is against the law.
