Didn't leave a message and then when I called back consistentl engaged

No message left. Number now blocked

Called and hung up when I said hello a few times.

silent xcall

Answering machine took call. No message. Rings 3 times/day.

A man called Brian claimed to be from Telstra and told me I had been hacked. He wanted me to tell him my IP address. I told him I can't do that. He became aggressive and said he was going to disconnect my internet and hung up

Called but hung up as soon as answering machine picked up. Very Annoying.

Keeps calling my direct work line and hanging up (3 times in the past week). Today called and was laughing and then hung up

Keeps calling and hanging up. Today called with a creepy laugh and hung up.

Picked up, said hello, didn't hear anything, caller hung up

This person claimed to be a Telstra technician and wanted me to check my IP address, saying I was being hacked. I hung up and rang Telstra to confirm. They said it was a scam.

Scammer, Indian accent. A number of these sort of calls the last few days. I wish Telstra would deal with them.

As above - I did not pick up. Can't wait until our telco's begin blocking the buggers!!!!

Rang my home phone and said he was Peter from Telstra. Went on to say that a Mr Johnson had hacked my "landline". He then quoted an old address of mine and I told him he wasn't from Telstra because Telstra knows my address. I didn't let on it was my old address and so he went on to blame it on this Mr Johnson. He then wanted to know my current address which I refused to give him and told him if he WAS from Telstra, he would know my current address. When I told him this proved again that he wasn't from Telstra, he called me a f-----g idiot ... I then told him that that proved for a 3rd (or was it 4th) time he wasn't from Telstra as they wouldn't use language like that, he just kept calling me an effing idiot at which point I hung up on him.

Try to tell me there was a problem with my internet but wouldn't tell me who my internet was with wanted passwords I told him if he was from my internet provider he would know my account number and then i would talk to him he hung up on me. I rang the number back to check and it is a disconnected number

Claiming to be NBN. Rang back, just got busy signal each time I tried.

Scammers claiming to from the NBN and started asking about passwords.
That's when I hung up.
