I had missed a call from this number and they left no message. When I called the number back, a recorded message told me that the number was not connected. This indicates to me that it was a scam attempt.

Caller: 0485 855 477

Tried to call me didn’t answer as I was already on the phone

I picked up the call, which appears to be from an Australian mobile number (but could be spoofed). As soon as I answered, the caller hung up. Blocking number.
