Answer 1:
*69 THEM
You can ask them who calling when they calling or you can just *69 them.
You can also call the telephone company and have them send you a list of names and numbers that have been dialed or received to and from your phone.
Answer 2:
If you see the number on the screen, you may call them back (blanking your number) and ask them. If you don't have their number, you can report to the phone company if the calls are harassing.
Another thing you can do is Google the phone number. Often times a listing will be shown.

It is impossible to see who is calling you under private. the only way to know is to let your answering machine take care of it or aquire a telephone number tracking device that only cops have.
I'm wondering how to do that myself. I don't think there's a way to check it, unless you ask you're service provideri want to chenk who is calling me private.
