I have been getting a call every day from the same number for the last three weeks...I have tried calling Engin and they are unable to assist.  I have also tried calling it back and it sounds like an International ring tone, and again no one answers.

this number (02) 8986 0316 has called continually over the past few months it is very disturbing it rings and when you answer hangs up,also when you return the call it is a unusual ringtone and it never answers

I receive a call from this number very regularly (about once a week). When I answer it goes dead. WHen I ring it, it has a very unusual ring tone and no-one answers.

Just had a missed call from this number. I'm in Perth, Western Australia. I won't be calling it back, as it's probably a scam or a machine which is logging whether your number is active, what time you pick up etc. That information could then be on-sold to other telemarketing companies.
