Fibre, VOIP & powercuts

[medalto]

wanting to upgrade to Fibre. 

But

I live in rural Scotland and power cuts ( esp in winter) are a regular feature. 

I need a reliable 24/7 landline for work (Hosp  Dr , and phone needed for on call emergencies & Stuff)

I dont get a reliable mobile signal through the 2 feet thick stone walls of my 19th century croft. even on the window cill its very intermittent.

If there is a powercut I loose VOIP .

So how can I power the router ( and phones) to ensure a landline during power cuts

thanks

@medalto Purchase a UPS. There are websites which calculate the power requirements for you. If the power cuts are protracted then you'll need a auto-starting petrol/diesel generator.

You are going to need a UPS (uninterruptible power supply), basically a big battery.

However, if your phones need power, they won't work in a power cut, even on the PSTN, (Public switched telephone network) which will be switch off by the end of 2025 anyway.
