We live in the state of Washington. Received a call from this number at 10:47 am (Pacific Time Zone). Caller ID said Phoenix AZ. We didn't answer and they didn't leave a message. We will block this number.
Got a call saying "you have a live conference call, press one to be connected now." I didn't sign up or know of any such conference call so I didn't press one, obviously. The recorded message did not give any information about who was on the call or what the call was about. My concern was that if I did I would be authorizing unwanted charges. I will block as well.
