Caller: Male caller

This call showed as coming from Brisbane, Qld. When I answered there was a delay of a few seconds, followed by a "plop" sound and what sounded like background noise of a call centre. A male caller (with a strong Indian accent) told me that his name was Jason and he was calling me about upgrading my NBN speed, then he started asking me questions about my modem. I told him that I was away from home and I'd call him back, then I hung up. I would say it was a scam attempt.
