I posted a query about two years ago about wiring my home phone system to my VDSL router. I can now report that I have now moved to the Vodafone IP phone system and successfully connected it to my home wiring. All jack points in the house are now live and working. It took a Sparky under half an hour and cost under $100 to disconect the home network from the PTSN.
