Skip - Yes, I crimped all cables myself. And yes, I have made mistakes and had to re-crimp, so I thought you might have had it pegged.
I rounded up a 20 or 30 foot store-bought Cat 5, plugged it directly into the x10 port, but it still clicked.
I was side-by-side with an x18 phone at the same desk, and here is what I tested:
x11 calling my cell: Click on all 3 outgoing lines.
x18 calling my cell: No click, and I only tried one line.
x11 calling x18 via intercom: No click. However, we have heard clicks on intercom in the past.
