Is there a way to secure my VAPI assistant? I mean when he accepts all incoming calls and can be spammed, I have a huge problem with huge invoices. How to handle that?

Absolutely, I can help you with that! Here are some best practices to secure your VAPI assistant and manage incoming calls to prevent spam and high invoices: ### 1. Set Call Limits - Concurrency Limits: Configure your VAPI assistant to limit the number of simultaneous calls it can handle. This helps manage traffic and reduces the risk of spam. You can adjust these settings in your voice API platform's dashboard. ### 2. Implement Security Measures - Credential Protection: Ensure your Twilio credentials are secure to prevent unauthorized access. - STIR/SHAKEN Compliance: Implement these protocols to authenticate calls and reduce the chances of your calls being marked as spam. ### 3. Use Fallback Destinations - Set up fallback numbers for when your assistant reaches its call limit. This way, additional incoming calls can be redirected instead of being answered. ### 4. Monitor Call Behavior - Keep an eye on your calling patterns. Avoid high-volume, short-duration calls that can trigger spam filters. ### 5. Register with CNAM - Register your number with a CNAM database to ensure your business name appears correctly on caller IDs, which can help reduce spam flags. ### 6. Usage Monitoring - Regularly monitor your call usage to avoid unexpected charges. Setting up alerts can help you stay informed. By implementing these strategies, you can significantly reduce the risk of spam calls and manage your costs more effectively. If you need more detailed steps on any of these points, just let me know! 😊 Sources: - [Best Practices for Securing a VAPI Assistant](https://discord.com/channels/1211482211119796234/1211483291191083018/1324731877235359816) - [Configuring VAPI Assistant to Limit Incoming Calls](https://discord.com/channels/1211482211119796234/1211483291191083018/1334517022893150218)

@User At the moment I'm using those free vapi phone number as well as the Web-snippet and among others present them both on my website for people to test it. Since it seems I have 0 control about the phone number or how often someone starts a call, anyone would be able to call that number over and over again or even spam with 10 concurrent calls forever. So what am I supposed to do? If that happens, my credit balance burns away.

@LAwLessLy Implement access control and rate limiting mechanisms in your product using different methods to ensure it meets your requirements.
