(07) 5578 8008 is a spammer form Robina, Qld.

This nuisance called late at night when calls are not permitted from spammers and leaves no message, just hangs up. I'm also on the Do Not Call Register.

Answered call and they (it) hung up after 5 seconds. Called it back and goes to Telstra Home Message Services. You're now added to my black list :)

Spammer called twice today. First time went to VM and spammer left no VM. The second time I answered and said nothing and this prompted the spammer to actually say "hello" and it was a female voice - I got you! As soon as I said hello the spammer hangs up.
