Analogue or digital ?

[scooby1]

I am asking for advice please and would very much appreciate it anyone could advise me on what I'm sure is a very simple question but because of my age I am struggling a bit. We own and live in a private household with just one telephone line and at the moment we have a Gigaset telephone base station and 2 subsidiary phones in 2 other rooms. We need to update the phone system because although we have renewed the AAA re-chargeable batteries in all 3 handsets they all keep losing their charge during any lengthy conversation.
We rather like the PANASONIC KX-TGU433EB system https://www.currys.co.uk/products/p...MIwpD-8-OIkgMVvZZQBh1nzQ_DEAQYByABEgKnlfD_BwE
but are in the dark about whether we should be buying a system that plugs into our router as well as the BT wall socket. We have a splitter socket mounted on the wall that was installed by a BT chap which plugs directly into our main BT socket and which both our telephone system and our EE Smart router are plugged into.
We live in a very small village which in fact has the BT exchange in it, we are about 300 metres from the exchange. My question is, should we buy a system that will work out of a router as well as a normal BT plug if all lines are eventually changed to digital ? Apologies if I have been typing nonsense but I really could do with some help.

The change, will be to fibre, and the router will have a phone socket in it, into which to plug your phone. Any phone, or phone system can be plugged in, so get what ever phones you like now - they will work.

Your AAA cells should keep the phones in use, going for hours - Are they decent quality cells? Are you dropping them back on the charger base, after each use?

Thank you @Harry Bloomfield that was very much appreciated. I had a look at my router manual and it wasn't very helpful but I have taken a snalshop of one of the pages and would like to ask you where the phone cable would plug in to the router ? We have got the double socket option on the wall and the router plug goes into the LH side as shown and the phone plug goes into the RH socket and then into the back of the phone base station. Where would it go in the back of the router ?

With regard to the batteries we fitted new Duracell re-chargeables into all the handsets when the systemstarted playing up. One of the individual handsetts doesn't always ring when we get a call.
