I have been getting a series of robot-voice scam phone calls from 040204xxxx numbers (the previous ones were Amazon iPhone bill scams from 0402 042 740, 0402 049 364, 0402 046 833). The 0402 042 778 one this morning was a (foreign-sounding) male voice sounding as if he was reading from a script, alleging I had a legal case pending against me for tax fraud, it being left on my answering service. In all cases I was asked to press "1" on my mobile phone to get details of the alleged (iPhone bill/tax fraud) allegation. Scam watch web sites suggest that these are attempts to get more of my details to facilitate further fraud. Sounds like a good candidate for blocking.

Fake scam alleging I had a legal tax bill, and that I had to press "1" for more information.
This type of scam is apparently used to attempt to gain your personal details. Seems like a good number for blocking.
