Basic Troubleshooting Chart
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.
