Just out of curiosity, do many people have Telstra Home Phone connections purely for the internet? At my previous place I had one, but the phone was never plugged in. I just had it for the internet.
If this is you, is there a reason why you didn't choose naked internet over this?
We have a phone that barely gets used. Only when someone occasionally rings us, telemarketers and when we can't find our mobile phones we use it to find our mobile phones.
No naked ADSL available in most regional centres. So we are forced to pay for the landline + Internet.
Hopefully NBN soon so that it can be done away with for good. Although I will probably port the number to some cheap service just to hold onto it.
