Most motherboards have a "On restore power" setting, if you set that to
"power on" it will power up after a power failure (which is what you are
doing). If that setting isn't present there is another easy way, connect the
power switch to the  circuitry that toggles the power with some sort of a
delay, if you are using a pic for this then it is easy to do. How are you
controlling it over the phone line? Thanks, TTYL
