I get noise - hissing sound. Random. Ok for months, then every 2 or 3 days, then OK for weeks..There's a box on the outside of the house where I can plug in a phone. There is no noise there. So problem is inside the house. Picking up noise somewhere. My [B]incoming[/B] shielded cable is grounded. Also, there is a terminal block beside my breaker panel to which these incoming 4 wires (and ground) attach to this block. I have 4 phone cables coming down from the ceiling joists to this block. I plan disconnect one phone line at a time to check for noise. Slight problem doing this: All reds are on one screw of terminal block. All greens on another screw. All yellows attach to the same terminal as the ground.??? All blacks from my 4 phone wires are all connected together with a wirenut. Blacks are not attached to terminal block.??? SO, I'll have to disconnect [B]everything[/B] to separate the 4 lines. I realize the yellow and black aren't used, but why are the yellows connected to the ground? After I separate everything, should I re-connect the yellows to ground? Why? Is this weird wiring causing my noise?

Yesterday I found a [color=#202122]Ericofon by Ericsson, also called the Cobra, the other day and bought it. A friend still has a land line (running through his cable phone company box) and I plugged it in. Works great, made a call and everything. [url]https://en.wikipedia.org/wiki/Ericofon[/url] Honestly I bought it to sit in a cabinet and look cool, not to use. However like the old black and white TV I would like to be able to show say my Grandson (without having to find a working land line) how it works. Thus I am here. I of course have internet and a cell phone but I gave up on TV years ago. On line I have found a few things like this: "[/color][color=#000000]magicJack HOME VoIP Phone Adapter (K1103)" I doubt this will work because the phone is rotary. Does or did something exist that would convert rotary signal to pulse? (not sure what the push button hones were called) Or do I just have a relic of the past. Willing to look find and buy what is needed but don't know what that is. Thanks[/color]
