NOTES:
This provides a first-level screening for calls where caller-IDs are tagged as anonymous. If this is not filtering calls as expected, it's likely some added layers of configuration settings need to be reviewed:

The caller may have added a layer of deception about the call, using techie-geeky strategies such as using a zero phone number 000000000 to a marking a SIP flag as "privacy=true". If these kinds of calls persist, follow the steps above for "to confirm the correct number" from your SmartPBX log and manually blocklist the specific number.
If you are a Private Cloud or Global Infrastructure client and use your own carrier, your carrier may have a unique strategy for dealing with anonymous calls that KAZOO doesn't anticipate. Check with support to help review your call logs.

If your blocklist assignment is still letting calls come through, you may need to contact support so they can analyze your SIP call logs and Carrier settings at a more detailed level.
