9:07 p.m.  Dead air.

Multiple  calls.   Busy signal on the messages.

I heard talking in the background. I asked who it was. I will keep her name anonymous but she said that she was conducting a survey. I asked how she got my number, she said it was dialed by random. I said I was on the do not call list,  apparently surveys don't apply to it. I politely asked to be removed from the call list. She said ok, have a good night. They were very polite.

A survey, charities & political calls ARE exempt from the DNC list.

And of course scammers. If anything the scammers use the DNC to get working numbers to call. Skip the DNC and use a blocker instead.
