I answered, heard a beep then a crackle then nothing.

Scam

Must be a scam call as all my phones rang at the same time. Answered to hear a tone and they hung up. Answering machine took the other call and it kept recoding even after they hung up. We need to get these calls stopped. Some I have answered when I ask what it is about tell me to GET f*ckED. We do not need these calls and we need the Govt to act on it. They can legislate to stop these scammers getting acces to Australian Numbers.

I answered, heard a beep then a crackle then nothing. Rang it back - received a message that it has incoming call restrictions

This number reaches my message-bank and does not leave a message. Number is unknown to me. Likely scam or nuisance caller.

Unsolicited call. Suspect scam
