Mobile rang immediately after land line had rung, saying missed call. With landline there was silence when I answered so I blow a whistle down it.

These canvassers ring then hang up before you can answer. They are most annoying. This number has rung before & claim to be canvassing for a reputable company. They get you talking, then when you tell them not interested, I gave at the office or goodbye, they try to re-engage you. My opinion is not to answer these calls & if you do "Dont talk" just grunt. I have heard of callers recording your voice & trying to use the recording for voice recognition services like the tax office ( Melbourne ) or Centrelink. I know this because it happened to me. Be VERY CAREFUL.
