 To begin with, your key word is 'sometimes'. What this means is that your
neighbor may be using one particular band (or group of RF frequencies) that
the ole Kitchen phone is particularly sensitive to. Talk with your neighbor,
if he is like *most* Amateurs, he will work with you to determine the cause
of the interference and help resolve it. Some of the more modestly-priced
telephones are notorious for their lack of filtering, no matter; they can
be equipped with a filter and the cost is quite low. ($3-5)

 Yes there are laws that regulate the spectrum purity of Amateur RF emissions,
but be forewarned, the likelyhood of the problem being at his end is very
low compared to it being a problem with your phone and or extension wiring.
 The FCC hears complaints like this all the time, most are simply logged and
nothing is done about them unless a large number of complaints are received
from ALL the neighbors of a particular radio operator. Talk to your neighbor,
he is (most likely) as interested in solving the problem as you are, since
bad PR could cost him if the problem *is* with his equipment. The FCC will
(in severe cases) limit his activities, with 'Quiet Hours' if no other means
can resolve the issue.

 Your neighbor will most likely ask you to participate in a simple series of
tests to determine which band or mode causes the problem. Once identified,
such things as filter caps, chokes, etc. will most likely have to be added
at your end, be cool, these items will not harm your phone and in fact are
nominally added for free by the telephone company, to insure quality service.
