I haven't had a land line in nearly 8 years.  I just had a cell phone
for most of that time and now VoIP plus the cell phone.  Of course I
haven't had an emergency where I had to dial 911 in that time, so I
cannot really say if that is sufficient.

I recognize that in an emergency cell towers will likely be overwhelmed
or down anyway, so just my cell phone may not work so well, or the
battery will die, etc.  But if a disaster of that magnitude were to
strike, I would think the 911 call centers would be overwhelmed as well.

The emergency that has the highest chance of occurring to most of us is
probably something happening while traveling in a car.  Neither a land
line nor VoIP is that useful in those circumstances.  So I have to
depend on the reliability of the cell companies.  And as we've
established 911 in that case works pretty well.

For other situations, my ham radio (with a supply of alkaline batteries)
will hopefully be of some use.
