THanks guys for the above info getting called by(03) 9246 4700- I am in hong kong at the moment and it is really really s**tting me off. If i answer the call I will get hit by roaming charges. They are not even bothering to listen to my absent voicemail message. If they ring me again I will report them.

I just tried ringing the number and it is Telstra.  They advise that they are calling about a service that may interest me, however I can only call them during office hours on 1800 726 594 (9am - 4:30pm M-F), but they can call me whenever they like.

I advise anyone who receives these calls should ring the 1800 number and ask to be removed from their caller database.

If I am near my phone I press the answer button, wait 5 seconds then press the hang up button. Figure I might as well annoy them as much as they annoy other people.
I accidentally answered a call from one of these numbers when working from home, thought it was the office calling me. It was someone doing a survey. I
told them my consultancy fee is $160 per hour plus GST & I will answer any questions once I have received their payment. They hung up & haven't called back since. My phones are both on the "Do Not Call" register.

Same here.  Repeatedly.  I'd say upto 50 times a day off each number.  Being a shift worker, it sucks because its always while I'm asleep.  I haven't answered because I know it's a telemarketer.

still receiving calls

I got a call from this number the other day.  I tried to answere it but they hung up as soon as I answered.
