Probable Cause
The Gateway was
disconnected, then
reconnected after
configuration changes were
made to the system.
The Gateway was configured
on another network or has
returned to the system after
being deleted from the
system.
The maximum number of
four PSTN Gateways and one
T1 Gateway for the site has
been reached.
The Gateway is failing to
synchronize with a Deskset
configured for a different
system configuration.
Line calibration allows the
PSTN Gateway to adjust its
performance depending on
the phone lines'
characteristics. The Gateway
may not have performed
calibration.
Corrective Action
Refer to "Reintroducing a Gateway or ATA Into the
System" on page 260.

added.
Always disconnect the LAN cable from Desksets before
restoring factory defaults (by pressing the RESET button
more than five seconds).
Make sure an Ethernet cable is plugged into the port
marked LAN.
Unplug the PSTN telephone line and wait two full seconds
for the Gateway line LED to turn red before plugging it back
