Setting off a nuke somewhere? )

depending on what you want to do, you could just pick up off the ringer
(sounder) or the LED lighting circuit in the phone. Drive the LED in an
opto-coupler from the same circuit - this will feed very nicely into
anything you want. - just pray you don't get a TXT while setting up ))))
