Caller: Male caller

This call showed as coming from Brisbane, QLD. When I answered there was a delay of several seconds, then a male voice with an Indian accent who said his name was Alex started asking me question about by solar panel rebate scheme. I told him that I was quite content with my existing arrangements and the call was terminated from the other end. I receive calls like this almost daily (always from different numbers) and strongly suspect it was a scam attempt.
