Dear Forum,
Yesterday, I was trying to troubleshoot my downstairs phone. My upstairs phone works fine.
Downstairs, the phone line is in rather poor shape. The phone line connects to a socket whose screws are corroded. When I jiggled the socket, I got a tone. However, a few moment later, the downstairs phone would not give me a tone. More surprising, the upstairs phone would not give me a tone either. I had to wait about 10 minutes before getting a tone upstairs.
Does anybody know what could have happenned?
I greatly appreciate your help.
