- 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.
