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.
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-50.
You can set up a picture or design to be displayed on the background of the
graphic display of all SoundPoint IP 550, 560, and 650 phones. There are a
number of default backgrounds, both solid and bitmaps. Users can select
which background appear on their phone.
You can modify the solid backgrounds and bitmaps. For example, you can add
a grey solid background or modify a bitmap 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.
a
Locate the background parameter.

For the solid backgrounds, set the name and RGB values. For example:
c
bg.gf.gray.pat.solid.3.name="Gray"
bg.gf.gray.pat.solid.3.red="128"
bg.gf.gray.pat.solid.3.green="128"
bg.gf.gray.pat.solid.3.blue="128"
