If you are using a digital telephone, this is what I would expect. When we tone out a digital circuit, the LED on the toner shows similar results.
Try the phone on a different extension, and another phone on that extension. You could have a bad phone or port. -----Original Message----- From: kxt-boun...@kxthelp.com [mailto:kxt-boun...@kxthelp.com] On Behalf Of Lancia Ersatzteilservice C.C.

I did measure the circuit, and could not find a a short. Does anybody know about this effect ?
