[SGVLUG] home automation question - maybe asterisk?

[Claude Felizardo]

Asterisk might be overkill but I'm looking for a simple way to use the
unused 2nd line at home to control the computer using DTMF via modem.
I can get it to work if it has line power but I want to use the 2nd
line feature of my cordless phones.  While not Star Trek, it would be
cool to pick up any extension and punch in some commands and have it
act on it.   Voice command would be even better.  Having to bring up a
web browser just to turn off all the lights outside takes too long but
if I could use a phone that would be much quicker.   Simple scenario:
hear noise in middle of night, pickup phone extension in bedroom, hit
a few keys and turn on all the lights but the bedroom lights using
x10.

Now I don't need VOIP so that's why I'm guessing Asterisk would be
overkill but it looked like the menu-ing system would be handy.  I
just need a way to interface the existing analog phones in the house
to the computer.  Suggestions?  Links?
