I have very strange problem, and hope someone out there has an idea how
to fix it. I have a 2-line phone, but I get a loud hum on line #2 when
I have both lines plugged into the phone. When just line #1 is
connected, the signal is very clear. I am pretty sure that the problem
is inside, since I've checked each line at the NIC outside, and both
are clear. I have replaced the standard twisted pair wiring with
cat-5, but that hasn't helped. I thought it was the phone and had that
replace, but that didn't fix it, either. Any ideas? Thanks
