What comes up on my screen is:  SATYAM BPO Saty

I got this too. The message he left was that he was calling from somewhere in Rhode Island.

770 area code is Atlanta GA, not RI.

I got three calls in a row after I did a Live Chat with Verizon Fios over an issue that we were having with our OnDemand service.  They said that I left the chat window open, I told them it was closed and my computer was off and then they hung up on me but haven't bothered me since.

I have gotten 3 call and nothing when I answered.
