To help safeguard your SIP accounts from potential misuse, we’ve introduced a powerful new feature in the latest version of VSM4—Maximum Rate Limiting. This feature is designed to prevent unauthorized usage, protecting your system from hackers who may attempt to make expensive calls by manipulating call rates.
What is the Maximum Rate Limiting Feature?
The Maximum Rate Limiting feature allows administrators to set a maximum allowable rate for each SIP account. This means that if the rate for any call exceeds the predefined limit, the call will be automatically blocked. In addition, the system will notify the administrator of the suspicious activity, allowing for immediate intervention.
How Does It Work?
- Set a Maximum Rate for Each SIP Account:
- Administrators can now define a maximum rate for any SIP account in VSM4. This is the upper limit for the cost per call that the account can incur. If someone takes over retail client account and tries to make expensive calls, the system will automatically recognize and prevent it.
- Blocking Unauthorized Calls:
- If a call exceeds the maximum rate set for the SIP account, it will be instantly blocked by the system. This ensures that unauthorized calls to expensive destinations or attempts to manipulate call rates are effectively stopped before they can cause financial damage.
- Admin Notifications:
- Alongside blocking the call, the system will send a notification to the administrator. This alert will detail the attempted call, the rate that triggered the block, and other relevant information, allowing the admin to quickly assess the situation and take further action if needed.
Why Is This Feature Important?
- Prevents Fraudulent Activity:
- The primary goal of this feature is to protect your system from potential attacks, particularly scenarios when account was taken over to make high-cost calls to premium destinations. You effectively mitigate the risk of financial losses from such activities.
- Real-Time Protection:
- With automatic call blocking and instant notifications, the system offers real-time protection. Administrators are immediately alerted to any unusual activity, allowing for quick responses to security threats.
- Customized Security:
- Every SIP account can have its own maximum rate, which means you can tailor the security settings to the specific needs of each account. Whether it’s a high-volume account or one that rarely makes international calls, you have the flexibility to set appropriate rate limits.
Getting Started with Maximum Rate Limiting:
To enable this feature, log in to your VSM4 system and navigate to the SIP account settings. From there, you can set a maximum rate for each account based on your requirements. The system will automatically enforce these limits, ensuring that any call exceeding the specified rate is blocked and flagged for review.
Conclusion:
The new Maximum Rate Limiting feature in VSM4 is a crucial tool for securing your communications infrastructure. By preventing unauthorized rate changes and blocking suspicious calls, you can protect your system from fraud while ensuring that your legitimate communications remain unaffected. We strongly encourage all administrators to implement this feature to enhance the security of their SIP accounts.
