Called my house. Answering machine picked up. No voice, no message, just static.
Caller i.d. said "unknown".
I don't answer "unknown" calls. If you don't know who you are, don't call me!
The reality of the world is that the "Do Not Call List" has no effect on the behavior of criminals. A computer calls telephone numbers, the caller blocks or spoofs caller id information. If you answer the call, they give you some spiel about Credit Card consolidation, owing money that you really do not owe, or as with the above number "diabetic supplies". I don't need them, but someone who answers might and they might be temped to supply this unknown caller with credit card information which will lead to theft of money at best or identity theft at worse.
The above number has "unknown" caller id information. Do not answer it. Block the call. Criminals have no moral code.
