They called, let it ring twice, then waited until someone here picked up. Minutes later we got a robocall from a different number. It was like they were checking to make sure someone was here before the 2nd call with the scam-pitch.

Btw they have been 'disguising' their numbers as international numbers too. Second call came from 011-583-000-2582. We have no friends outside the US, yet this was 3rd int'l call in the past month ... why would someone call from outside USA to sell someone health/burial insurance for Americans?
