Received a call from this number.  I answered and they just sat there. I got irritated and hung up. They called back with a restricted number which means they *67 so I couldn't see their number.
They called me a total of four times and the messages that were left were sounded like they were recording me because it was a recording of my voice mail. And the second one was me trying to answer the call. Either some kid playing on the phone or some of Yahoo being a jerk.
