SSI is Survey Sampling International. They get paid to conduct surveys of various types including political surveys. As long as the survey does not lead to any kind of sales attempt, even by a third party, they are not required to screen against the Do Not Call list. Their computers will continue to try and call numbers that are not answered as long as the survey is active. They have a link on their website where you can opt out of future calls.
