Our business has received several calls from this number over the past few days - always hangs up when we answer. Ring it back and a recorded message states "You have been contacted by a hosted contact service. You may be contacted again in the future". I hardly call it 'contact' when all they do is hang up in your ear. Very annoying. Sounds similar to calls received from (02) 9112 5710 (of which there are numerous comments on this website). Telstra can block the number ($2.50 a month) if you request it but I suggest that if you do actually get someone talking to you from either number - get a loud whistle or alarm and let them really know what you think.

The (02) 9112 5723 is the Commonwealth bank flogging some new product. They have rung me twice in less than 24 hours. The salesperson on the other end was very pushy/annoying so I eventually hung up on them. Shame we just can't make them pay for our wasted timeor just not ring us at all.

this number keeps calling me but i never answer calls if i don't know who it is.. strangers can leave a message. But they don't leaver messages.

I am now looking at registering on the Do Not Call government register, anyone use this service?

Still making their stupid calls. Never leave messages, and when you answer they hang up. May this is a Today Tonight job!! I have entered their number in my phone with the name being DO NOT ANSWER.

Hi, I just got this call too but when I answered it, it hung up on me. Not gonna call it back. Hope that this isn't the beginning of a lifelong harassment!

Hey these guys are calling me every day at 10.30, i never answer as i dont know the number. Thought i would Google it so see who it is, and this came up. Tried calling them up and got the pre-recorded msg as well, will answer tomorrow to see what happens...
