I don't know about UK, but here in Spain all clients on fibre have a 
VoIP system, hidden. At the home, there is a device called ONT (Optical 
network terminal), which can be integrated on the router, that converts 
the phone over IP signals to an RJ-11 where we connect our traditional 
phone terminals.

In fact, companies hide the VoIP credentials so that connecting a VoIP 
phone instead is not trivial.

The stated goal is to remove all copper exchanges, migrating everybody 
to fibre (or some form of radio). The buildings can then be sold, they 
are in the city centres and are worth a packet.

My understanding is that the UK is doing more or less the same, and many 
countries are on the same road. Which means that a lot of the current 
phone network is no longer circuit switched.
