Local connections during internet outages

As someone who has suffered with a number of internet outages this year - it is annoying that the chimes disconnect every time. Why can’t my whole ring system stay connected on a local basis? Then when internet is restored it just starts working over internet. Currently, after my internet is restored by my provider, I have to spend 20 minutes or more reconnecting the chimes and then the devices connected through them. I know it isn’t your fault for internet outages but I’m getting fed up continuously having to reset my network of ring products.
