Polycom SIP 3.0.2 manual Graphic Display Backgrounds, Which background appear on their phone

Administrator’s Guide SoundPoint IP / SoundStation IP

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 Quality of Service <QOS/> on page A-50.

Graphic Display Backgrounds

	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.
Note
	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: a Open sip.cfg in an XML editor.

b Locate the background parameter.

c For the solid backgrounds, set the name and RGB values. For example:

bg.gf.gray.pat.solid.3.red=”128”

bg.gf.gray.pat.solid.3.green=”128”

bg.gf.gray.pat.solid.3.blue=”128”
