Landline owners, assemble!
is it an actual landline or has it been converted to a digital subscriber line, because there is a difference.
Even most landlines today just relay to a fully digitalized VoIP infrastructure. The new stuff is just way more economical to run, even if the residences still run kilometers of old copper wire, the hubs have changed to microwave antennas or satellite uplinks, as they are much cheaper to maintain.
Cheaper and a lot more flexible. If you abstract the actual call into packets sent over the internet, you can make use of routing and redundant links that are already in place, or easier to build.
