# Callback Configuration

This page explains how to configure callback URLs to receive key event notifications from the voice platform, such as call status updates, call detail record (CDR) generation, and recording file availability.

## Accessing the Feature

1. After logging in to the Call Center platform, navigate to **Voice** > **Settings** > **System Settings**.

2. On the **System Settings** page, select the **Callback Configuration** tab.

## Configuration Items

* **CDR Callback URL:** Receives call detail record (CDR) data.
* **Call Status Callback URL:** Receives real-time call status events, such as **Ringing**, **Answered**, and **Disconnected**.
* **Predictive Task Status Callback URL:** Receives status updates for predictive outbound call tasks, such as successful calls and unanswered calls.

**Note:** Callback URLs must be publicly accessible **HTTP** or **HTTPS** URLs and must be able to process **HTTP POST** requests from the platform.

## Procedure

1. Enter the appropriate callback URL in each field.
2. Click **Save** to apply the configuration.

When a relevant event occurs, the platform automatically sends a notification in **JSON** format to the configured callback URL.
