Hung up as soon as answer machine picked up the call.

Caller: Scammer pretending to be Telstra

A woman saying she was from Telstra told me my account was about to be terminated.

Caller: A female person with a strong accent probably from the sub-continent.

I believe this is the same number that called me with a ZFSendToTarget scam. They tried to convince me to remotely access my computer on the basis of a non-existent problem and using a number which is common to most computers as evidence they knew my computer unique CLSID number.
They asked to download and install a probably legitimate remote access program by Philandro software called anydesk. This program warned me with a message that no legitimate organisation will cold call me trying to get remote access which is what this lady had done. This was before I had allowed them to remotely access my computer.
I stated this to the lady and she stopped talking although the line sounded connected she would not respond to my "hellos". I then hung up. A few minutes later she rung up again and tried to talk to another member of my household.
I would hang up if you get any more calls on this number.
