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
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.
Best Practices
Configure an account-level stop rate appropriate for your calling requirements.
Regularly review blocked numbers and dialing patterns.
Monitor call activity and update fraud control settings as your business needs change.
Using these fraud control features can significantly reduce the risk of toll fraud and help protect your account from unexpected charges.
