Is it possible to block all "No Caller ID" calls?

[DocSteve]

The majority of No Caller ID calls to my iPhone are prank or sales calls.  Is it possible to block all "No Caller ID" calls?

DocSteve,

That's a great question. Getting No Caller ID or Restricted calls are not fun. I know where you are coming from, I personally like to know who's calling me. I'll be happy to help. Check out #5 on this link: Caller ID and Caller ID Blocking FAQs | Verizon Wireless  .

This does not work if you do not have the number (NO Caller ID)
