Cisco 8832 Administration Guide

ExplanationSummary
If you power your phone through the network
connection, you must be careful if you decide to
unplug the network connection of the phone and plug
the cable into a desktop computer.
The network card in the computer cannot
receive power through the network
connection; if power comes through the
connection, the network card can be
destroyed. To protect a network card, wait
10 seconds or longer after unplugging the
cable from the phone before plugging it
into a computer. This delay gives the
switch enough time to recognize that there
is no longer a phone on the line and to stop
providing power to the cable.
Caution
Moving a network connection from the phone to a
workstation
By default, the administrator password settings are
locked to prevent users from making changes that
could impact their network connectivity. You must
unlock the administrator password settings before you
can configure them.
See Apply a Phone Password, on page 37 for details.
If the administrator password is not set in
common phone profile, then the user can
modify the network settings.
Note
Changing the telephone configuration
The RxType and the TxType statistics show the codec
that is used for a conversation between this Cisco IP
Phone and the other device. The values of these
statistics should match. If they do not, verify that the
other device can handle the codec conversation, or
that a transcoder is in place to handle the service. See
Display the Call Statistics Window, on page 134 for
details.
Codec mismatch between the phone and another
device
The RxSize and the TxSize statistics show the size of
the voice packets that are used in a conversation
between this Cisco IP Phone and the other device.
The values of these statistics should match. See
