But a land line? If I pick up an analog phone anywhere, I expect a dial tone, and local calling. If I don't have access to emergency services after a blackout/natural disaster that knocks cell towers down (think hurricane season in Florida last year) then you'd never get me to drop my local carrier.
I think it is quite a bit to expect very high reliability even from land lines during and immediately following a hurricane. In fact, the odds may not be bad that your cellular service could be restored before your land line. Funny thing about blackouts, you're IP phone is dead if your ISP link depends on utility power. Your cell phone is OK. Your land line is OK... as long as you don't just have cordless phones that require a base station that only operates plugged in. <Gratuitous-Plug=Employer> If you really want high reliability during and after a natural disaster, satellite phones are probably your best option. We just opened a new gateway in Florida, partly due to demand for emergency services support during hurricane season. (Although I'd rather not slide into the discussion about how 911 works for us.) </Gratuitous-Plug> As any network engineer knows, the best engineered systems still do fail.
