So BT / Openreach plan to retire PSTN by 2025, going Digital Voice. When this happens, how would one diagnose an ADSL / VDSL line fault as a consumer? Currently the first go-to is to plug a known good hardwired analogue phone into the test socket and dial 17070 and listen out for crackles and pops on the quiet line test. It would be good to know, if an analogue phone is still connected post switchover, that there's some sort of automated tester still on the line based in the exchange, even if it doesnt connect allow you to call any other number.
What do those on migrated Digital Voice services get today if they plug an anlogue phone into the master socket? An automated message? Is 17070 still live post switch over?
