Thanks @Echo the husky. We have thought about doing the same bur our landline was also our business line back in the day and quite a few local people still use it to call us.
Thank you for that @Echo the husky. May I ask if you are isolated and way out in the sticks because surely if you have a few neighbours they should also be experiencing similar problems ?
Thank you for that @mattylad. I have quite a few items with re-chargeable batteries in, head torches, label printer, oh, and of course do not forget all the Christmas lights that get draped round everywhere !!
Thank you @spile. You may have a very good point there. Our existing system has been working vwell for about 6-7 years (I think). Perjaps it is "Planned obsolescence"
Thank you @mattylad. The 3 handset system that we have at the moment has Duracell re-chargeable batteries in each handset and so long as the handsets are left in their stand they are charged fully. The problem is that the charge doesn't last very long and they are nearly new batteries.
