Jayson,
I've heard very bad reports of phone service provided by cable
companies. This is not surprising, considering that they probably know
very little about providing telephone service.
How about the following idea: since you already have an asterisk box up
and running, why don't you become your own telephone provider? Find a
wholesale provider from whom you can buy a local telephone number;
outbound service wholesale costs a couple of cents a minute, and I think
there are even providers that will allow free local calls within a
portion of your own area code. You may even be able to port your
current phone number.
The only thing you would need is an Internet connection, either "naked"
DSL or from your cable company. You might want to invest in a UPS for
selected parts of your setup.
Of course the whole 911 issue needs to be dealt with, but may be easily
solvable by careful choice of provider...
