You hear echoes, distorted
speech, or static.
At least one of the PSTN
lines has DSL, which is not
properly filtered.
 Make sure you have a DSL filter plugged in between each
DSL line and the telephone wall jack.
 You may need a higher quality DSL filter than you are
using. You can also try plugging in multiple DSL filters in
sequence to decrease DSL interference.
 Move the DSL line to the lowest priority line, which is Line
4 on any Gateway.
There is a non–system set
plugged into one of the
telephone wall jacks.
 Remove any parallel systems from the PSTN line
(connected through a splitter, for example) such as an
analog phone, fax machine, or alarm system.
The Gateway did not
recognize a new PSTN line
being plugged in, so line
calibration — which allows
the Gateway to adjust its
performance depending on
the phone lines’
characteristics — did not
occur.
 Confirm an Ethernet cable is plugged into the Deskset
port marked .
 Ensure that the line LED is solid red before plugging in the
PSTN line.
 When unplugging the line, wait two full seconds for the
LED to turn red before plugging it back in.
