Caller left a voicemail regarding some sort of survey that would only take 6 minutes (!!) and the questions could be answered using the keypad (!!). Naturally I deleted it without doing the survey.

Get a call from this number every day this week at about 6:10pm asking who is my preferred Prime Minister. A few months ago Telstra advised me to have any phone numbers removed from the Electoral Roll as that is the trigger for this type of call.

Caller ID shows overseas but its a sydney number asking to do a survey the first question is asking who you would prefer as prime minister I just let is go to answering machine, they are also ringing my mobile. Have received 4 calls in the last 24 hours. What a scam

This is for Lincoln Research. They ring every night at 7pm and a bit later on my mobile phone. It comes up on my phone as an overseas number.

I called back number (02) 9640 1700 reached voice mail of a guy and mentioned it was regarding a research poll.

Same... Caller ID says overseas, but number has Sydney prefix.... I didn't answer it.

Caller ID indicates 'Overseas' but the number appears to be in Sydney or thereabouts (I think). Just wonder if it's a scammer coming in from overseas via an Australian number. I didn't pick up to find out.
