I don't answer numbers I don't know, but these people are persistent in letting the phone ring for over two minutes if a machine doesn't pick up.

Caller ID Lists them as: SOI KS

Got a call from SOI at this number--who is SOI? I let answer machine take calls from those I don't know, delete them later. I have to assume that this is one of those "give me money" a**-clowns.

Looks like SOI KS is from Special Olympics, Inc

From 8:00 am to 8:30 pm, these people will not stop. Been going on for several months. Told them last 2 year I was not going to give to them but they keep calling and try to say "Thank you for your gift from last year." I told them this was a lie, then they said it must be an 'accounting error'. Then I hung up. This year more calls. Let'em ring.
