Thank you for the detailed reply and the explanations to (mostly) all the jargon :-)
Sweden is also doing a lot of deprecation of old telephony systems, those that I know of is that 2G and 3G are going away by 2025.
The less tech debt we pass onto future generations, the better.
In the UK at least, the POTS (Plain Old ...) copper phone lines carry an electrical current as well as signals and can power the handset. There are certain guarantees about this so that in an emergency your phone will still work so you can dial 999 (our original emergency number) or 112. Our fire regulations require something like 30 minutes before things should start failing. In the real world, you get out immediately and use your mobile.
We have an emergency alarm monitoring system used by businesses. Its generally known as "Red Care" which was a brand run by BT (British Telecom). You have a small device connected to a phone line (and powered by it) and it will monitor your fire detectors and building access control systems and a 24 hour manned monitoring centre will notify you in the event of an emergency. Nowadays, these devices will use your wifi and internet connection. Sometimes: old school is best.
I respectfully disagree.
I had redcare via Age Concern for my mum before she went into a home with dementia - it was a few years ago and it was all that was available.
Nowadays, the panic alarms are, I believe, entirely self contained using a sim card and mobile connectivity and include location information - so they are not reliant on local power or internet connection. That locational information could be life saving - one time my mother got very confused, left her flat and was wandering around outside in freezing conditions. Luckily someone heard her calling out and took her home, but she could easily have died that night and was so confused that she didn't think to use her dongle which was still around her neck, and it is doubtful it would have been in range of her base station anyway. A modern system can also include geofencing and even positional data (if someone falls down), takes it off, or battery runs low and automatically alert. Just like redcare, the modern systems are manned 24/7 just the same.
Sometimes old school is not best.
I think we might be writing at cross purposes. The system you had for your mum obviously worked effectively for you and that is the important thing.
POTS provide(s|d) a fixed point of reference - your address is registered against the number for 999 etc; it provides power for a handset or device; Its been like that for a lot of decades! These are cast iron guarantees. A POTS line has guarantees, enshrined in UK law, that mobile etc does not have. POTS is circuit switched (well it was) which means there is a physical path between the ends for the duration of the conversation.
So, by old school, I mean that you currently have important guarantees about telephony in the UK that will evaporate in future. In 2025 or so, we in the UK will have finished migrating from our old school POTS copper lines and will enjoy our smart new SoGEA lines instead. Single Order Generic Ethernet Access. Instead of an emulated circuit switched line we will use VoIP across the entire country. Nothing wrong with that but it probably won't have the guarantees that POTS had.
Red Care is no more - BT have dropped it on the floor as of Feb this year which may indicate that things are not well with our future comms promises. The general system that Red Care was one product of is still available.
This is the important point: Promises (in law) that we used to be able to rely on for comms may (will) be binned.
I was thinking about getting a landline again (US) simply because VoIP and cellular all have issues with latency I find jarring.
