# 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.
