When I answered, the guy on the other end sounded as if he was Oriental (Japanese or Chinese). He had great difficulty expressing himself in English.
Told me it was not a sales call, but that he was representing a solar panel organization calling to see if my home qualified for special financing to lower my electrical bill.
Since his English was poor, he put his "supervisor" on the line, whose English was not much better. When he fished around to see how much I was spending on electrical costs every month, which I told him was less than $100/month (which it sometimes is), he said I did not qualify.
As he was about to hang-up, I asked him how he managed to get my telephone number, but I did not quite understand his response. Then I asked to have my number removed from his system. He responded with, "Sure, sure," and that was the end of the call.
