The number originates form a company called Salmat, a telemarketing business who works on behalf of their clients to engage with consumers. Best thing to do is answer the call and before they launch into their scripted talk 1) ask them to tell you in 5 words what the call is about, 2) ask them where they obtained your number and 3) request them to immediately remove you from their call list and advise them you are on the do not call register (if you are). I always add that if they call again, they will be reported to the Australian Communications and Media Authority. It seems to work for me. :-)
