If ALL of the phones are ringing, I suspect the Comcast box is telling them to ring. I would try a good K9YC 80 meter choke on the phone line right where it comes out of the Comcast box. Then I would also try one of those same chokes on the power supply going to the Comcast box.
7 turns through a #31 ferrite clamp-on or toroid should do it.

I am working with another ham to solve his unusual RFI issue.
He uses Comcast for internet, TV and phones. When he is on 80 meters, it
rings the phones in his house.
He hasn't tried anything, yet, to cure the problem.
