### Answer I don't have information in the available sources about blocking specific spam numbers from calling your Retell AI agents. However, the documentation does cover how to prevent your outbound calls from being marked as spam by carriers. If you're experiencing issues with your outbound calls being flagged, Retell provides two services: [(1) ]() 1. Verified phone numbers - Retell will register your number with phone carriers so it won't be marked as spam 2. Branded call - Recipients will see your business name instead of a generic number Both services require a verified business profile first. If you're looking to block specific incoming numbers from reaching your agents, I'd recommend checking out these potentially useful sources or reaching out to support for guidance on call filtering capabilities: - [Spam likely overview]() Would you like me to try to provide a general answer based on my knowledge instead?

For blocking inbound spam callers, you would typically need to implement call filtering at the telephony provider level (Twilio, Telnyx, etc.) or through your agent's logic, but I don't have specific documentation on how to configure this within Retell AI.
