# Callback and Security Settings

This chapter introduces the basic configuration options related to system integration and data security in the voice platform.

# 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.

# Security Settings

This page describes the security settings available in the voice platform, with a focus on protecting sensitive customer information such as phone numbers.

### Phone Number Masking

To enhance customer privacy, you can enable **Phone Number Masking**. When enabled, the platform automatically masks sensitive phone number information (such as caller and callee numbers) when displaying or pushing data.

## 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 **Security Settings** tab.

## Configuration Items

### Phone Number Masking

When enabled, phone numbers are partially masked (for example, **138****1234**) in the following scenarios:

* Call records displayed in the console
* Phone numbers included in exported reports

**Note:** This setting affects only the displayed data. The original call data is still stored in the system for billing and auditing purposes.

## Procedure

1. Turn the **Phone Number Masking** switch **On** or **Off** as required.
2. Click **Save** to apply the configuration.

**Tip:** It is recommended to enable this feature in scenarios involving customer privacy, such as outbound customer service calls and call recording playback, to help meet data security and compliance requirements.
