This number has called my home phone twice recently - on 4/29/09 @ 9:58am and 5/4/09 @ 10:01 am. I'm not at home during this time. They have not left a message.
I get all kinds of telemarketing calls all day. Most of the time if it's a number I don't recognize I wait a couple of seconds before answering. Then I can tell if it's a recording or not. I think this was an automatic dialer of some kind. Boo telemarketers!!!
