Got this call on Saturday afternoon.  I don't know what SSI stands for but the first thing I would think of is Social Security but of course NOT on a Saturday.  Spam for brains probably didn't think of that.  Blocked.

It is probably Survey Sampling International, a large company that has many phone numbers it uses to call people for surveys. There are many complains on 800notes about this company.

They have a webpage that explains how you can get your phone number on their internal do-not-call list so that none of the numbers they use in the future will call you.
