Not sure what the point is of ringing & not answering then they hang up.

They call to validate your phone number. Once you pick up, their job is done and they hang up.

i'm in Sydney, don't know anyone in Melbourne so not answered, then looked here, glad I did

hung up when I answered the phone

Answered the call, line open but no one responded when I did so. Absolute misuse of telecommunications services!

blocked them. Thanks for logging your comments.

Same here.

Much as above - silence, then a muffled voice, then they hang up.

Caller: some debt broker

I think we need to start to lobby the Federal Aust Govt to take action on these blasted nuisance calls I am cancelling the phone number

Pointless call, no one talked, then it hang up after 10 seconds

Hang up caller.

Seems like they're looking for active phone numbers by seeing if anyone answers. Block it.

answered phone it was silent then they finally said something background i could hear them ordering fried rice in Chinese sounds like a scam to me

Hung up after 3 seconds when I answered the phone.

They hung up as soon as i answered

another annoying waste of time caller
