I missed a call from (03) 9871 7436 and when I called back, "Message box is full, and cannot accept messages at this time, goodbye"

Rang back and got american voice telling me the voice mailbox was full

Supposedly ???? from Telstra to let me know my IP Address had changed from Private to Public and that all my computer details would now be accessible, he would then like to fix that problem. Lots of other callers in the background. When I said it sounds like a scam call to me, he immediately hung up.

claimed to be Commbank reporting a fraudulent action on my account, straight out scammer.
