We just found out we can now get VDSL at our place so I went looking to upgrade our plan, but looking at it the price seems to jump up by $10 per month if I am an existing customer. It seems this is due to the free national calling being included in the new sign up price but as an added extra for existing customers.

It doesn't seem to indicate any special new sign up pricing or anything like that s what is the reason for this discrepancy?
