extension to test this suggested solution.
Display shows an error/
informational message
Most messages involve server/phone
interaction.
If you are on a call and the display suddenly
shows “Discovering...,” the network connection
between the telephone and the call server was
interrupted, but your call stayed connected. The
telephone automatically starts to re-register with
the call server, but until re-registration succeeds,
you do not have access to switch features and
functionality such as Transfer, or to
administered Feature buttons.
If you cannot resolve the problem based on the
message received, contact your System
Administrator for resolution.
Characters do not appear on
the Display screen
See “Phone does not activate after connecting it
the first time.”
Check all lines into the phone to ensure that it is
properly connected.
Check the power source to ensure that your
telephone is receiving power.
Perform the following Test procedure: with the
telephone idle (on-hook), press and release the
Mute button. Then press the following numbers
on the dialpad: 8 3 7 8 # (which stands for
TEST). The display should indicate the self-test
has started, then report if the test was
successful or failed. If nothing appears on the
display, and the phone is receiving power, your
phone might need to be replaced.
If these suggested solutions do not resolve the
problem, reset or power cycle the phone with
your System Administrator’s assistance.
