I know. I really feel like wireless landlines should have more protection against that sort of thing. With the ones I've had at least, if the hub connected to your phone line loses electricity, the handsets are essentially beeping bricks nagging you about a power cut. I really wish this was factored into the design more.
It would be interesting to see a wireless landline that also worked as a standard phone, when docked into the main hub. When you dock the phone in the hub, there's two copper prongs that make contact. Surely they could be used to pass-through analogue telephone signals in the event of lost power to the hub?
Oh, addendum: I actually have an old sage rotary telephone I can put my hand on, but of course the line doesn't support pulse dialling so you can't actually ring out on it (though it can take incoming calls). It can't 'press' numbers, either. Such a shame.
You can actually convert pulse to tone signals through something called a DTMF module. In short, you take apart the phone, move around some contacts, add one or two resistors (and of course the module) and you're off to the races.
Oh, while writing my comment I found out there's actually discrete modules for pulse to tone conversion that you MITM your rotary phone with, so no DIY required. You can buy them from a few online stores[0], too.
