Scammer call, answered put myself on mute and could hear a scammer saying hello

This number - supposedly a Canberra area code - called my mobile today. I didn't answer and no message was left. Scammers.

Caller: (02) 5110 8045

Been called by this number and others with the same six initial numbers numerous times per day for a few weeks. They never leave a voice message.

Called from this & 8048 as well. Random times, No message ever left... I've not answered as they're not in my contacts

This number has been phoning randomly for a few weeks now at various times during the day and night. If answered it is AI voice that answers and I just hung up and now it is blocked and goes straight to SPAM but they are persistent.

Went unanswered. No message was left.

Called several times but never left any message

Did not leave a MESSAGE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
