I told the caller that my number is unlisted and is on the "do not call" registry, then asked him to immediately remove the number from the calling list - he responded "no, no...." and I hung up before he could say anything else
Medicare scam, their fist call was on 646-502-9110 saying I had equipment I could use or ordered via medicare. I have not requested nor do I need any medicare services. Heavy accent, I said it was a scam, hung up then got immediate call back on a new number.
