No caller ID Calls

[Hannahm1]

I keep receiving No Caller ID Calls, this is out of the ordinary for me and is becoming frequent. They are not leaving messages so it leads me to believe it is someone I know who is in my contact list. 

Is there any way I can either A: Find out the number calling me? or B: block the no caller ID?

lotsa spam and spoof calling these days. If you don't recognise the calling number or don't see the calling number...just don't answer the call. If it's a legit caller, they can leave a voicemail for you. The bad guys will keep calling as long as they know you answer all calls.
