If the tech come and you already have a splitter installed, just ask for the splitter as a spare part, think it cost around $75 for one them ! ...LoL
I did but the guy said no.
He looked at the old Corning POTS splitter that I'd bought on eBay many years ago and said it would work fine on ADSL/VDSL so I didn't need a new one. I was in a hurry so I didn't try to argue.
