Caller ID Sunnyvale CA. Hangs up and leaves no message. Call preceded by 'Unavailable' with no number ID an presumably to validate your phone number and test blocking. Typical scammer/political solicitation/harassment tactic.
Rings 3 times, and hangs up; no message. I blocked my CID and called it back, some guy answers. I decided not to say anything and just waited in silence... he said hello a few times, and hung up,... I am not sure, I feel somewhat satisfied that I got to reverse the roles here... taste his own medicine.
Calling numbers back doesn't help matters, in fact can make them worse. Its bad because the numbers are spoofed as a ROT. You could be calling some innocent persons number or a innocent business that had nothing to do with the calls. While we understand that is is a frustrating thing, its just a bad idea.
Consider buying a call blocking device or phone. Many are around $50.00 and can block up to 1500 numbers. If its a cell phone, some already have call blocking, if not, there are free apps on the web that will work for some. You can google this. If u have a smart phone, there is a free app called call control. Iphones appear to have apps also.
