I am looking for a device that will alert me if another telephone extension is picked up. I dont need an un-defeatable circuit, just something that will work in the average home. I know RS used to sell such a device but I cant seem to find one. I would greatly appreciate any pointers to ready made or home brew devices. Thank you. Preferably, please respond via e-mail to xrsbg@dirac.gsfc.nasa.gov. -- -- Steve Green <xrsbg@charney.gsfc.nasa.gov> NASA, Goddard Space Flight Center, Centers For Computational Sciences, Code 931
