Who called from 2138057389

Call was from Los Angeles, CA.......did not answer and they are now on my call block list.

I swiped my cell phone to answer and did not say a word and it hung up.  I started doing this for all numbers I do not have in my contacts and so far, they all hang up without saying anything.  Pretty certain they are robo calls.
