Lucky I found this site in google!!!I had the same missed call number & when I answer the phone they kept breaking up.  They said they were from ICT (Westpac???)I really worried it is something urgent!!thankyou so much for this site!!

just called the company ICT, the number is (02) 8268 3600 and had my name removed from the calling list, I too have been getting a few phone calls a day while Im at work.Starting to frustrate me badly. Hopefully this works :)

I live south of Sydney and have 2 missed calls on my mobile.Tried to ring back but no dial tone.

same deal!

were we getting charged everytime we tried calling back?

The number displayed on your phone console is referred to as a CLI or a Caller Line Identifier. It is not necessarily a number that can be return dialed.  In the instance of (02) 8915 4600 this particular CLI is from an outsource call centre.  The outsourcing centre calls on behalf of their many clients.  The company washes their records to the National DNCR if there is no ongoing business relationship.  It is not the intent to deliberately harass any customer and are willing to suppress any records upon request.
