Vonage

Introduction

The Vonage channel allows you to connect your Exei AI Voice Agent to toll-free or local phone numbers for handling inbound voice calls.

Exei integrates with Vonage Voice API to enable real-time AI-powered voice conversations over phone calls. Once connected, users can call your number and speak directly with your AI agent.

What the Vonage Channel Supports

Using the Vonage integration, you can:

• Connect toll-free or local phone numbers

• Handle inbound voice calls using an AI agent

• Enable real-time speech-to-text and text-to-speech

• Support call interruption and natural conversations

• Track all voice calls in Exei’s Conversations module

• Use feedback, Instant Retrain, and Human Takeover

This channel is ideal for call centers, support lines, and automated inbound call handling.

Answer URL & Event URL (Important)

In Exei, the Vonage setup screen provides two URLs:

These URLs must be copied exactly as shown in Exei and pasted into the Vonage application settings.

How Voice Calls Work After Setup

Once the setup is complete:
