Polycom SIP 3.1 manual Graphic Display Backgrounds, SoundPoint IP Switch - Port Priorities

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. To disabled the PC Ethernet port, refer to Disabling PC Ethernet Port on 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 Quality of Service <QOS/> on page A-55.

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, 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.
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.
