You're being obtuse. Maybe this will help:

They removed the analog phone line. And replaced it with part of a
digital voice, data, tv bundle.

No analog phone. Period.




Now THERE'S your problem!

Nothing digital is ever reliable to the extent that the analog it replaces
is/was. About the closest they get is CD/mp3 audio, which is fairly
reliable, but each has drawbacks. Even if you got no electricity or
batteries, you could still play a vinyl (or bakelite or whatever) record...
all this fanciful digital hoo-haw will fail us when we need it most. Sure,
it's nice to be able to lug around a lifetime's music collection on a device
smaller than a pack of cigarettes.. but..
