Are you using an answering machine?
An answering machine should be connected directly to the port located inside the left side panel of
the product that is labeled with the telephone icon or should be shared on the same phone line
extension. Set the product’s rings-to-answer for one ring more than the number of rings for which
the answering machine is set. See
for more information.
If an answering machine is connected on the same phone line but on a different jack, it may interfere
with the product’s ability to receive faxes.
