What's the best way to move from Spark xDSL Clothed to Spark VDSL Naked, and port landline number away to a VoIP provider?
Can the POTS line be kept active, so you can port out? Or does this cause things to collapse as Spark don't do "fully" naked?
Can you get Naked VDSL installed on the second pair instead? Would this mean extra cost, or is it covered as a standard VDSL install?
