Ahh, the wonderful folks from C&P telephone and their quality demarc boxes.
What's happened is that there is current leakage between the ground and your
phone line someplace.  Could be that the demarc box is getting wet.  Could
be that the lines in the house are getting wet someplace.  Disconnect the
line at the demarc next time it gets bad and plug a phone into the box...
if you can still hear a hum, call C&P and place a report with the craftsmen
and make sure someone is there to explain that it's a ground imbalance
problem when the guy arrives.

If it's inside the house... well, you're going to have to start pulling
things apart to locate the problem.  Could be anything from a bad phone
to wet wiring.
