Who called from 2151888133

WHO IS THIS

I don't know I just got a call from this number as well.. really long silence, then the guy says " hello, hello" and then hangs up

I had a call from this number on Saturday and they hung up when I answered.  Then about 45 minutes later I had a call from 800-100-1000 selling me something about a time share.  I asked for him to take me off their list and do not call again.  Just got another call from this 215 number and again they hung up.  Let's see if I get another call from a mysterious sales number.  I wonder if this is a phishing call looking to see if the numbers are live and then they sell them.
