Probably a scammer. I didn't answer.

Caller: Indian woman claiming to be from Telstra

Answer call and there's the usual giveaway: A long pause, a loud clunk, then someone comes online. It's an Indian woman, very strong accent. Says she's from Telstra.
"Do you know about your IP?"
"What, my IP address?"
"Yes, do you know your IP is now switched to public from private?"
[Yeah, right. Here we go.]
"You're from Telstra?"
"Yes, sir, I am calling you today from the Telstra."
"OK, can you give me your extension there at Telstra and I'll call the Telstra office to speak with you."
"Yes, sir, you can call me back at Telstra."
"What's your extension at Telstra?"
"Thank you, sir, and have a nice day."

Indian woman claiming to be from Telstra. Tried to scare me by telling me that my IP address has been made public! Haha. I asked for her extension at Telstra so I could call her back -- at Telstra. Naturally she couldn't and terminated the call.

Received a call from (02) 4444 1263 claiming to be from Vodafone offering discounts. The lady on the other end then sent me a log in link from Vodafone (which is a legit log in link sent out by Vodafone) and requested for 4 digit log in code. It is believed that she is trying to gain access to my Vodafone account.
