Sorry to hear you are still having such problems. Have you complained to BT’s CEO or Chairman (as I suggested above last year) or Ofcom?
I have lodged complaints with both of those. To no avail. I also wrote to my MP Tom Collins who was equally dismissive. I will not be voting for him again. The Strowger system was 100% reliable. It didn't generate enough revenue for BT / Openreach. So loyal customers of six decades have now been foisted with this cost cutting invention of theirs. Not only have the standard charges also been vastly increased for all subscribers. But local calls have now been phased out.
Where I live I have now to use the trunk dialling code for my next door neighbour. And be charged at trunk rates.
The so called roll out is a shambles, a farce and a scandal. I am lucky I have an amateur radio chum who helps me out as necessary via VHF radio. I feel as though I am living in the Australian bush not the English Midlands

What a load of nonsense. Strowger disappeared decades ago.
There is no such thing as trunk calling anymore, again hasn't been for decades. Even when it was in force, you would only be charged local rates if dialling the full STD code for a local call.
Have you complained to your power company about the power cuts?
My, oh my ? We do have a high opinion of ourselves, don't we ?

Have you requested, or tried, one of these?

PS Strowger switches were not 100% reliable - far from it - and required a huge amount of (expensive) maintenance to keep them working. They also took up a lot of physical space.
TBH , lamenting the demise of electromechanical telephone switching , when since that technology was current , we have had electronic exchanges, then digital exchanges and now IP telephony, is similar to pining for horse drawn carriages when presented with an electric vehicle (EV) , without referring to the internal combustion engine , IP telephony isn’t replacing Strowger , its replacing digital exchange equipment.
if power cuts happen often in your area why don't you invest in cheap PAYG mobile phone?
TBH , the OP states they use VHF radio to contact others during power outages , presumably this has a power requirement that is independent of the ‘mains’ , so a fallback power supply for telephony shouldn’t be unfathomable.
