I answered although the number calling was unrecognized and supposedly originating in N.Y. Caller knew my name although my direct line is via a VOIP connection. Voice was likely computer generated. I asked if this was a computer and was asked what I thought. I stated "Computer". Voice then stated Medicare records indicated I had knee and back pain and asked if this was correct. I responded "No". Voice hung up. This appears to be a very sophisticated scam weakened by the apparent computer generated voice. I only wish the Federal Government Call Blocking List was more fully enforced but, unfortunately, the federal government is currently very ineffectual in several areas.
