Who called from 4842201183

called on my mobile.

Didn't pick up when they called but my caller ID says the call was from this number.  Attempted to call the number back and all the time it says "All circuits are busy now...blah...blah blah"

Called me at 10:21 am Pacific time. I did not answer and instead of calling back, I looked up the number online, which brought me here.

called me this morning 11:25 am eastern time; called back and pressed '1' to be put on "do not call" list

Yep. I dint answer either. Googled my way here. Thanks folks !
