<SNIP OLD MESSAGE>

The first thing I would do is call up your telco and tell them to fix
their lines (this assumes you arein the U.S.) as they have to provide
clear POTS lines. It could very well be that for some reason that the
static is causing issues with the FXO cards. Get the lines fixed first
and then troubleshoot the * system.
