Timely reminder. UK are shutting down fixed/pstn lines as of 2025 so this is the end of the road if any hacks still exist in the wild.

Can get a small bit of that feeling of communicating for 'free' across vast distances with amateur radio.

That's interesting, I thought ADSL is piggybacking on that infra...?

On a physical layer, yes: ADSL runs over the same copper lines. But the upper layers are quite separated. Moving everyone to VoIP means less infrastructure needed, things working the same for fiber and ADSL customers, and higher speeds for ADSL (due to being able to use the frequency bands reserved for phone service for data too). This has been a general trend in countries that are using ADSL a lot, e.g. here in Germany plain analogue and ISDN service has been reduced more and more too.
