When you answer the phone, there is a small beep and you know yo are being connected to someone, since its just an automated phone system. The person, who has a foreign accent that I could not identify, is trying to tell you that a new insurance plan is offered in your state and everyone...EVERYONE...is eligible and they would like to have someone call you back with more information. They are persistent when you say no.
Scammer are trying to trick people into thinking that more local calls are legit. If you see a number from your state or a city near you ( I am in northeast Kansas and Lacrosse is only 3 hours away), you may be more willing to answer and fall victim.
