I get these calls at least once a month and sometimes as frequently as once a week (I'm in Perth Australia and they call from India). I always tell them I need to change phones to be next to my PC then I place my phone next to my speakers which are normally blasting out music and just leave it there. They are never on the end when I pick it up again but they do keep calling.
