Got a call from this number and a message. The message was the kind of message you get when you take to long to dial a number or have trouble making a call from a pay phone. The message was a female voice that said "could you please try again". Try what? I think that these calls are just from people who are fishing to see what informaton you are willing to give. Have you any idea how much information can be collected by a few fake calls. A person can tell even more if they are using call tracing software. I would not call the numbers back if I were you.
