Problem/Symptom Suggested Solution
Phone does not activate
after connecting it the
first time.
Unless your System Administrator has already initialized your
telephone, you might experience a delay of several minutes before
it becomes operational. Upon plug-in, your telephone immediately
starts downloading its operational software, its IP Address, and any
special features programmed by your System Administrator from
the server to which it is connected. Report any delay of more than
10 minutes to your System Administrator.
Phone does not activate
after a power
interruption.
Allow a few minutes for re-initialization after unplugging, powering
down the phone, server problems, or other power interruption
causes.
Phone worked earlier
but does not currently
appear to work.
Contact your System Administrator.
Speaker does not
operate.
Ask your System Administrator if your Speaker was disabled.
Phone does not ring. Use the Up/Down Volume keys to set your ringer volume to a
higher level.
From another phone, place a call to your 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.
