It depends, as others have noted, on how much stuff you have to run,
and how long you have to run it... and it depends a lot on regulatory
issues related to whether your phones are serving, say, people in a
rental property like a hotel.

On larger systems like that, particularly if you're driving lots of
remote phones and you're in a life-safety kind of environment (and if
you don't have a *firm* handle on what "life-safety" means, and "who
says so", run, do not walk, to hire someone who does :-), you're
probably going to find yourself *building* a UPS, with lots of big
deep-cycle batteries, and independent charger and inverter/rectifier boxes.

This can be an advantage, because it's easier to size the components
appropriately if they're individual items.
