Caller: Scammer

Highly likely to be a scam call. Failed to leave a message, called at the same time they usually call.

Caller: said they were from Telstra

The woman said that she was ringing about my internet connection and that my IP address had been compromised. She said her name was Christine Wilson and her Telstra ID was 18487. I cut her off before she tried anything else.

Caller: robot

One of those robot calls they use to check if a phone number is active. You answer, get 10 seconds of dead air before it hangs up.
