I'm sure that this is a very simple, but I need a device (LED & resistor??)
to tell me when another extension on my phone line is in use? Can I just
put this together myself with an LED and resistor (if so, what resistance),
or else is there a cheap one I can purchase?

Mail replies, as posting seems unnecessary.

Thanx in advance.
