it seems to me to be a spyware ,,if you answer it it will record all voice and messages on your mobile and or phone if you look the number up hear you get this web site for recording phone messages http://www.1300record.com.au/ourservices/mobilerecording.aspx?gclid=CIXU25ruzbQCFUcipQodOy0Anw

I agree. This number is one of several variants all starting with 028415--- the last four numbers change all the time and they are calling me about 5 times a day. I have not been able to call any of them back.

On call back you can't get through so suspect this number maybe a telemarketer or scam.
