I have used a grandfathered Optus ADSL service for 4 years and been delighted with their bundled phone, line and Internet package. I found that they offered a much cheaper bundle than other operators and also offered economical calls including free calls to Optus fixed and mobile numbers which I really liked. They also included options like a unlisted silent number in the deal which allowed us to avoid all the nuisance phone calls we hear so much about.
