It turns out this is a fellow with an Indian accent trying to get me to speak with an agent about buying insurance for my funeral expenses.  He didn't ask for anyone by name or give any information, and he didn't get a chance to ask me for any information.  I asked them to send the info in the mail, and I declined to speak any further about it.

This caller might be operating several different kinds of scams from this number - like magazines, sweepstakes, computer hacks - but they might have targeted me because I return-mailed a postcard asking for more information about the bogus insurance (I didn't give them my phone on that, though - only the info that was already on the card, address).

My caller was nice enough, as was I.  He politely apologized for the bother, although it really was no problem to me.  They seem to be up to no good, though, for sure.  Don't talk with them.
