# Fraud Control

The **Fraud Control** page provides security features that help protect your account from unauthorized usage, fraudulent calls, and unexpected charges. You can restrict outbound calling, set account-level rate limits, and block specific phone numbers or dialing patterns.

***

### Section 1: Call Restrictions

This section allows you to quickly enable or disable outbound call types for your account.

#### Disable International Termination

When enabled, your account will not be able to place outbound calls to international destinations (if previously enabled).

This option is recommended if your business only makes domestic calls and you want to prevent unauthorized international calling.

***

#### Disable Termination

When enabled, all outbound calling from your account is blocked.

This feature can be useful if:

* Your account is temporarily inactive.
* You suspect unauthorized usage (PBX/SPA compromized).
* You want to prevent all outbound traffic during maintenance or security incidents.

### Section 2: Account-Level Stop Rate

The **Account-Level Stop Rate** helps prevent expensive or fraudulent calls by limiting the maximum per-minute rate allowed for outbound calls.

Enter the maximum cost per minute that your account is allowed to dial.

* Calls to destinations with a rate higher than the configured value will be automatically rejected by the system.
* The minimum allowed stop rate is **0.001**.
* The maximum configurable stop rate is **0.50**.

If you require a higher stop rate, please contact your account representative for assistance.

#### Example

If you configure a stop rate of **0.05**, any destination costing more than **$0.05 per minute** will be blocked automatically.

### Section 3: Block Phone Numbers

The **Block Phone Numbers** feature allows you to prevent outbound calls to specific phone numbers or dialing prefixes.

You can block:

* A complete phone number
* A partial number (prefix/pattern)

#### Examples

| Block Value     | Result                                                                |
| --------------- | --------------------------------------------------------------------- |
| **19495551234** | Blocks calls only to this specific phone number.                      |
| **1949**        | Blocks all outbound calls to any number beginning with **1949**.      |
| **011**         | Blocks international dialing using the 011 prefix (where applicable). |

This feature is useful for:

* Blocking known fraudulent destinations.
* Preventing calls to premium-rate numbers.
* Restricting calls to specific countries or area codes.
* Enforcing company dialing policies.
