Who called from 8064962123

I received a call from this number just now and there was no answer when I picked up.  I said "hello" twice and there was not a response.

Unknown # called - I let it go to voice mail - left no msg. No clue.

Missed a call from this number, called it right back and get an auto-message from magicjack to save money on long distance and that this number is not assigned to a customer yet.

This caller called at 2155 (09:55) 4/09/2013. This is in violation of the do not call list.

Answered, no response from the caller, then the line hung up.
