SCAM wanted to know if I was transferring $800 to James smith in USA

Silence when I answered.

Caller: Said they were Telstra

Said that the IP address was public and I would have to change. Was an Indian caller, very loud in the background. It seemed they were trying to get a yes or a no answer

He told me that I had an unauthorised transaction to US for $800 and I had to get the security department to give them my IP address and other weird stuff. Definitely a scammer.

I just received a call from this number as well. I called the number back but it didn't ring, just silence.

Picked up phone, silence for 10 seconds, then heard a beep, said recording had finished then call ended. Definitely spam

Tried calling back. Did not answer, then they hung up. Total scam

When I rang back the number did not ring, there was silence for about 20 seconds and then I got the Call Failed screen.
