AC power adapter or can be line-powered (power supplied through the
signaling or idle pairs of the LAN Ethernet cable). Line powering typically
requires that the phone plugs directly into a dedicated LAN jack. Devices that
do not require LAN power can then plug into the SoundPoint IP PC Ethernet
port. To disabled the PC Ethernet port, refer to
page C-27.
SoundPoint IP Switch - Port Priorities
To help ensure good voice quality, the Ethernet switch embedded in the
SoundPoint IP phones should be configured to give voice traffic emanating
from the phone higher transmit priority than those from a device connected to
the PC port. If not using a VLAN (VLAN set to blank in the setup menu), this
will automatically be the case. If using a VLAN, ensure that the 802.1p
priorities for both default and real-time transport protocol (RTP) packet types
are set to 2 or greater. Otherwise, these packets will compete equally with
those from the PC port. For more information, refer to
<QOS/> on page A-55.
You can set up a picture or design to be displayed on the background of the
graphic display of all SoundPoint IP 550, 560, 650, and 670 phones. There are a
number of default backgrounds, both solid color and pictures. Both BMP and
JPEG files are supported. You can also select the label color for soft key and
line key labels. Users can select which background and label color appears on
their phone.
You can modify the supported solid color and pictures backgrounds. For
example, you can add a grey solid color background or modify a picture to one
of your choice.
When installing a background of your choice, care needs to be taken to ensure that
the background does not adversely affect the visibility of the text on the phone
display. As a general rule, backgrounds should be light in shading for better
usability.
To modify the backgrounds displayed on the supported SoundPoint IP phones:
1. Modify the sip.cfg configuration file as follows:
Open sip.cfg in an XML editor.
