Regarding emergency backup for voice calls, the company installing fibre in my area doesn't even offer a land-line phone replacement as an option. Their web site points you in the direction of a large VoIP call provider. There is no provision for battery backup.
I only use the land-line for freephone calls these days, anyway. The phone providers have priced themselves out of the market, when compared with mobile phones.
