Hello All,
I are using 2 4FXS/DID card and have a problem with it. They seem to generate a Hum on the lines they are connected to. We have ad the Bell and the Cabling cimpany out there and after they disconnect our cards the Hum goes way when we are reconnected the Hum re-appears. anyone have any ideas?
