This caller is out of control.  NUMEROUS hang up calls.   One person reported an Asian accent when the caller did speak.  Another tried to call the number, only to find out it had been spoofed (faked, a number that doesn't exist).   This is familiar with the scam artists overseas who claim to be someone else in order to seperate you from your identity information, or your hard earned cash.   I will try blocking but past experience is the scam artists just spoof another number, so I am chosing the "disconnnected" message hoping to stop the disruptions to my phone.  Meanwhile, if you have a bad day, when they call, say or do whatever you want, ...use a fog horn....  ...use foul language and pretend they are your ex....  in other words, this person is probably stealing a USA grandma's social security check, etc.  they don't deserve normal considerations, like respect or a listening ear.   Use this as anger therapy.   Since I let the one family lunatic answer my house phone, I have seen a 75% REDUCTION in unwanted callers.  Yes, there are always new ones so someday, I'll have to find a more efficient way to dispose of this time waster.  Forget reporting them to the FTC as this is untracable and probably overseas.
