Got 6 calls in 4 days. Phone was off. No message left. Returned call. Said invalid number.
6:44pm - 04/02/2012 - Caller ID shows TEXAS. Robo-call sets you up for person to get you to volunteer to have a home security system installed for free as long as they can advertise in your yard with a sign. The security system is wireless.
2 hang up calls from this # on the same day, 1 in the morning and 1 in the afternoon.
