Blocked Calls on the iPhone?

**Please ANSWER, READ DESCRIPTION**

When you *67 a number on your iPhone it still shows the contacts name like your calling the contact without your number being blocked or withheld.

Like when you type in (example) *67-555-5555 it shows their contact name, Frank, like your calling Frank without your number being blocked or anything.

My question is, when you call that person with *67, does your number show up blocked on their phone?

It will still show up as "Blocked" on the other person's phone when you call them with *67.

I received a call and the screen showed that it is a blocked number, but there's no blocked number in my contacts list. How is it possible? Is it a ios malfunction or another feature that i didn't know?
