       You might build a device which connects to your phone line and
detects off-hook voltage without off-hook current.  This indicates a
phone off-hook upstream of the device, so if placed just past your
demark, it indicates someone is using your line.  Use this to turn on
a tape recorder.  This should give you ammunition to deal with the
problem.
