I just had this missed call on my work line. Glad I was not in the office to pick up. I am wondering if this is the scam where they just want you to say yes, as JessicaP referenced above. http://www.omaha.com/money/this-phone-scam-ju ... 0657f1c1c0.html
They called my office, Indian accent. When I answered he said my name, I replied "speaking", and he hung up. If you call back you receive the "number not in service" error.
Calls like this are obvious phishing attempts to confirm your info. Save yourself the trouble and don't answer unknown numbers. If no message is left, BLOCK IT! On top of that the number is spoofed, a telltale signature of a SCAMMER!
