Some devices did not update after using .
An extension number was not changed correctly.
Probable Cause Corrective Action
Did not allow enough time
for software to update due to
a slow Internet connection.

Wait 30 minutes, then check whether additional
devices have been updated. If devices are still
being updated, then the Internet connection is
slow and you must wait for all the devices to
complete the update process.

If the update has failed (you see a failure
message), retry
. Allow sufficient
time for the upgrade process to complete. You
may prefer to schedule a system update to take
place overnight.

Update individual devices manually either
through the front panel or through the WebUI for
that particular device.

Power cycle each device that did not get
upgraded. Unplug the power cord and plug it
back in. As each device reboots, it automatically
updates if it detects updated software in the
system.
If you are using the WebUI to upgrade the
device, ensure that you log on using that
device’s IP address.
Probable Cause Corrective Action
That extension may have
been on a call while the

changed in the WebUI, or

no one is using that extension while you are
changing its settings.
