Yes, apparently they no longer do the install as standard, you'll need to pay extra if you want one.
No you don't use a phone filter (I assume you mean the plug in one for ADSL? No don't use it)
Now I am confuse. If I were to sign up to 2Degree and best connection on my street is VDSL, you mean I have to fork out $ for the splitter.
my ADSL filter not usable, so 12 month contract free installation is a joke? not to mention adding $15 to courier for the 7490 modem as well.
