KX-T: Problem with Off Hook

Hi, Have a 824 system with 16 phones, mostly models 7735 and 7736. My garage phone sometimes goes off-hook on its own during lightning storms. Any ideas? I have swapped phones etc to test and it is a recurring issue. The KSU is mounted in my basement with surge/ups on the power and phone lines.
