Yep. They have been calling my home phone for days, sometimes several times a day, using different numbers. CID says Arizona, Maine, New York, Iowa, ect., etc.. I just don't bother to pick up. If someone really wants me, they will leave a message.
As for the IRS scammers, and all other scams, most of them hang up before leaving a message. Those that bother to leave a message, it's always a recording about some fake BS.
