(253)555-0113 called my company cell line. When I answered a computer-female voice said: "You are the only person in this conference. You have been kicked from the conference." then the line disconnected (hung up). Sounds like someone is using a conference call feature to hide their real caller ID and make marketing calls which may not be in compliance with FCC do not call rules.
Just received a call from this number. I work from home on a company-issued computer. Heavily accented man said, "There is a problem with your computer, OK?" I said, "No," and hung up. Please do not give them any information and DO NOT allow these people to access your computer!
