Shot in the dark, but I would also check any lightening protection that may be on that line. On several occasions I have run into protectors going "1/2" bad and clamping down on the ringing voltage. I've had some that would do it all the time and some that would be more erratic. Anyay just a suggestion. Out of curiousity, is 301 a display phone, and if so does it dispaly noramlly when the problem occurs or does it say anything different?
