Call came in at 10:15am, no message.  Said Beachwood, OH and we don't answer City-State or unknown numbers now as they are almost always junk calls.  Which is sad as we run a business from home, too, and as the person said above, it is very distracting plus we wonder if we've missed a potential client call, but they would leave a message.  If I do happen to answer it and it is a fundraising call, for cancer or whatever, I tell them that I will no longer donate ANYTHING that has been phone driven and refuse to.  I donate by mail only after I've had a chance to check out the internet reports whether the cause is worthy, so they are wasting their time and mine by calling, and to remove my number.
