how to block "invalid" numbers?

Although I signed up for call blocking feature (dial *60 and then 2) it does not work on all calls. Some are supposedluy invalid numbers like 817-704-8708 and 135-647-8920.

Simple questions for Xfinity tech gurus,if there are any:

How can I or anyone be called by invalid numbers? Why is that possible? How to prevent it?

Thanks,
