After an initial silence on the other end, the caller asked for me by name, at first I didn't answer and she said it a different way, and I said, "maybe, who is this?"  She responded with the name Jane and she was calling about security system.  I asked what her full name was and what company she represented, she said her name was Jane Williams (I don't believe it, she had an accent) and she left the line.  After a few seconds I hung up.   I was not going to say "yes" to anyone I don't know over the phone.  Solicitor call.
