@CuriousCat Yes, there are several strategies you can employ to help block inbound spam calls to your VAPI assistant: 1. **Blacklisting Numbers**: You can maintain a list of known spam numbers and block them from reaching your assistant. 2. **CAPTCHA Challenge**: Implement a CAPTCHA-like system that requires the caller to perform a simple task that is easy for humans but difficult for automated systems. 3. **Call Analysis**: Use call analysis tools to detect patterns typical of spam calls, such as high call frequency or calls from suspicious locations. 4. **Dynamic Assistant Assignment**: Dynamically assign assistants based on the caller's phone number, using criteria that filter out potential spammers. 5. **Server-Side Filtering**: Use your server to filter incoming calls before they reach the VAPI assistant, based on your own logic and criteria. If you need assistance implementing any of these strategies or have other questions, please feel free to ask!

If number is purchased from Vapi, delete the number I will do the refund.
