The Voice OTP API calls a user's phone and reads a one-time code aloud (twice). Use it for signup and login verification, as the fallback when an SMS OTP is not entered, or with press-1 confirmation for COD order confirmation calls.

> **Ready to integrate?** Sign up at [voice-otp.edesy.in](https://voice-otp.edesy.in), create an API key and send your first voice OTP in a few minutes. No KYC is needed. See the [Quick Start](https://edesy.in/docs/voice-otp/getting-started/quick-start).
