# IP Whitelisting

> Restrict SIP access to trusted IP addresses for secure communication.

## Overview

IP Whitelisting is a security feature that controls which IP addresses are allowed to access your SIP endpoint.

<Info>
  This feature is available for **Enterprise plans only**.
</Info>

***

## How It Works

Whitelisting behavior depends on whether IPs are configured:

* **No IPs added** → all incoming calls are allowed
* **At least one IP added** → only calls from listed IPs are allowed

<Warning>
  Once you add an IP address, all non-listed IPs will be blocked.
</Warning>

***

## Why It’s Important

Whitelisting helps protect your system from:

* Unauthorized access
* SIP scanning and attacks
* Toll fraud
