Called me at home at 8:21AM on a Saturday morning. YOUR FRIEND was in caller ID, so I turned phone on and off immediately. Received a 2nd call about 5 minutes later, this time answered and just received dead air with a few clicks and then a dial tone. Attempted to call number back and was disconnected.
