numbers are requested, look at the label and provide this information to
your telephone company.

to your telephone line and still have those devices ring when your number
is called. In most, but not all, areas, the sum of the RENs of all devices
should not exceed five (5.0). To be certain of the number of devices you
may connect to your line, as determined by the REN (REN:0.7), you
should call your local telephone company to determine the maximum REN
for your calling area.

complaint with the FCC.
