Can anyone recommend a cordless phone system that will work during a
power failure? I guess the base unit would have to have a battery as
well as the handsets. I checked the Staples and OfficeMax big box
office supply stores, but all their phones fail in a power outage as
none have base-unit batteries.

Frankly I think it should be against the law to sell a cordless phone
that wont work in a power outage, but thats beside the point.

Has anyone seen a base-battery cordless phone system readily available
from the usual big box stores in the US?

I've got an old plug in phone for use when power goes out. I suspect my
computers back up batteries could also handle. Cheapest APC units could
probably handle a phone for many hours. Big power outage, I start my
generator.

As other poster pointed out, phone and cable companies have back-up
generators also. One of my EPA friends was looking into these mobile
pollution sources
