If POTS last mile is available, why complicate it with VoIP?

Have you considered using CPE DSL routers with VoIP and FXP analog out? Decentralized. That's what everyone are doing here. Might be free depending on where you get the CPEs.
Or simply getting VoIP handsets. Lots of cheap DECT bases with VoIP.

a 48 port dslam is 2200 (still awaiting cots on line cards for above
mentioned chassis) so its about 45 per port, CPE is about 50 a device
in bulk (inc 4 gb ports, wifi)
The copper exists, there is no ripping it out
Due to location RF links are used for data, so no need to give each
cabin "future proof" since unless a carrier will run fibre to us for
100's miles at their cost - it just aint happenin, the cost is
