They keep calling. Multiple times a day for past week or so.
I finally answered with “hello” there was then a delay and then an automated voice saying “we have an important message for you…” at which point I hung up the phone. Sounds like a scam/sales call - most likely oversees (although using a Melbourne number)

Caller: Telemarketers

I answered the phone and there was the usual 3 second delay due to them running a auto dialler. Then answered asking for some other name trying to get my name. Hung up.
