Caller ID says "Joe Sentari." I let my answering machine handle it. It answers all calls with, "We screen all calls. Please leave a message." He never leaves a message, I have no clue as to what he wants and really don't care.
These people keep calling, three times today already. Pressing 1 to talk to a "friendly" person results in a disconnect. Can't call them back to complain, either. Need to be able to block callers, like spam e:mail.
