(02) 9006 1550 called and no one says anything and just long pauses. I hung up and blocked the number based on the other comments above. Why is there so many of the dodgy numbers.

Call 3-5 times a day. Just left on hold when I pick up.

Caller: Regis Office Spaces

Given my number through genuine enquiry about serviced office spaces, however when they call there are long silences with no background noise or speaking. On their fourth call someone eventually connected with me and told me it was a recorded line. When I asked which city she was calling from (I have been looking in both Syd & Melb), she disconnected the call. Well... they have lost that business. Number being blocked.

I've been called a couple times recently, they never leave a message and the caller immediately puts you on hold if you bother to pick up.
I would suggest ignoring or blocking this number.

Yep i have received numerous calls from this number yesterday and one today so far, leaving no message, when i answer the call disconnects or puts me on hold.. I am not going to sit on hold for nothing..i am assuming its a telemarketer.

I picked up once, silence. Number has called me several days in a row.
