Who called from 2145506388

I've been receiving these calls (dead air) as well from this number.  I found this FCC form for reporting these kinds of calls:

https://esupport.fcc.gov/form1088/1088dform.do

It only took 2 minutes to complete.  Hopefully if enough people fill it in, something will be done

i have never had a subscription to anything, so i guess a phone list of some company got sold off somwhere

My mother-in-law would blow a really screechy whistle
into the phone for unwanted calls.  
It works!  Try it!  They give up after a while.
