This call showed as coming from Brisbane, Queensland. It also came with a notice attached (I presume by the service provider) which stated "Warning: Suspicious Calling Pattern". I did not answer the call, and the caller reached my message bank but did not leave a message. I received an almost identical call yesterday (from a mobile number this time) which came with the same warning message attached. In neither case did I have any human contact, however I believe that both calls were some sort of scam attempt.
