Who called from 5732063016

I answer, they hang up.

I answer, can hear background noise, (like call center) but no one seems to know I have picked up.

This number calls every day but no one speaks on the other end.

Just got the call, no one would answer.

This number has been calling me once or twice a day for a week.  Sounds like two 20 something year old guys when they (unknowingly) spoke on my voice mail one time.  Thanks to the others for leaving comments.  This site is helpful to have as a reference for these annoying calls!
