I had the same problem, except it wasn't just static Ð the phones
completely QUIT after a particularly rainy spell.
Turned out some of the phone wires were lying on the ground and
shorting out on the wet ground after rainy spells (very high water
table hereabouts, and rodents had chewed holes in the insulation I
guess). I had to re-wire the house.
