Introduction

Vonyx gives you Indian +91 numbers and a SIP trunk to call through them. Point any SIP client at Vonyx, or place calls with the Call API and stream the audio to your agent over a WebSocket.

Two ways to connect

SIP trunk

Your PBX, dialer or voice platform sends calls to Vonyx with a username and password.

Call API

One HTTP request places a call and streams its audio to your WebSocket.
