My nearly-new house has fttp and it's associated phone is surely digital. All handsets are connected by POTS wiring and sockets to a phone socket at the base of the 'ONT' box. Now multiple messages by post and email from BT urge me to convert to digital voice. Apparently I do so by plugging into the router green socket instead of the 'ont ' box.
The BT paper work explains nothing. Surely I have digital voice already?
Can anyone explain why this change is necessary? Hitherto I thought I understood how phones, both analogue and digital, and broadband work. I have not yet changed anything, to see what happens next.
What you currently have is FVA, fibre voice access which is an early voice system over FTTP by Openreach which is being discontinued in favour of a BT VoIP system known as Digital Voice. The faq describes it operation and possibilities.
