Caller: indian scammer pretending to be telstra

autodialler called my unlisted test number with a recording "this is telstra. your phone line is going to be disconnected. press 1 to speak to a technician or press 2 to have your phone line disconnected" or similar. you press 1 and you get an indian (with an english name) from "telstra technical support" who is reading a script to advise you of "errors in your internet connection". beware that this is a total scam. they will want to connect into your PC to convince you that you need to pay for services. don't fall for it.
