Caller said he was calling about my computer.  I told him i did not have a computer and he hung up!

This number calls several times each day about fixing my computer for me. I hang up

I got a call from that number, too. Whoever that was didn't leave a message. That number is on my phone's block list now!

There's a lot to be said about keeping regular contact with your family and friends. You know their numbers.  =)
It's easy to spot a weird call from 847-258-9541. Sorta like, 'Uh huh... What's this...?'

This number just called me at 6:15 AM on the Pacific Coast. It's bad enough to be constantly hassled by telemarketers but to be woken up 2 hours before your alarm is another. I didn't answer but as soon as my answering machine picked it up commonly heard recorded woman's voice (so often attached to telemarketers calls) is heard saying "Goodbye"
