It took two or three times saying Hello for her to respond. It was a woman with an Indian (I think) accent. She wanted to send me information on solar. I told her I wasn't interested and she said Thank You and we hung up.
Like everybody else ... phone rings and I answer because I have most annoying calls blocked automatically by my phone provider. Nothing on the end of the line. Then a computer generated voice that says "good bye." They are not manually blocked.
Call from 801-386-8041. Female with Indian accent said this was "Green Home Initiative" and they were contacting people in my area about solar power. I told her I wasn't interested and hung up. Only answered because I have relatives in the 801 area code.
Answer: Maybe. A list of good phone numbers (a 1-page sheet) can sell for between $5. and $7. When you consider that all the crook has to do is use voip, a computer, some cheap software, and then dial millions of numbers a day. The computer does all the work. Which is why it's usually a good idea not to answer, or call back unknown numbers.
