Caller: Recorded voice message

When I first answered, I could hear a woman with an Indian style accent say something but couldnt understand what, then the call seemed to 'click over' to a male robotic sounding voice. The recorded message stated something along the lines that my business tax file number had been suspended and if I wanted to prevent being arrested, needed to respond by typing 1 on my key pad. I didnt do anything and the call disconnected. Checked on ATO website where it claims many are being scammed in a similar way. I have blocked number.
