IEEE 802.1p/Q

The phone will tag all Ethernet packets it transmits with an 802.1Q VLAN header for one of the following reasons:

•When it has a valid VLAN ID set in its network configuration

•When it is instructed to tag packets through Cisco Discovery Protocol (CDP) running on a connected Ethernet switch

•When a VLAN ID is obtained from DHCP (refer to DHCP Menu on page 3-7)

The 802.1p/Q user_priority field can be set to a value from 0 to 7. The

user_priority can be configured specifically for RTP packets and call control packets, such as SIP signaling packets, with default settings configurable for all other packets.

Configuration changes can performed centrally at the boot server or locally:

Central	Configuration file:	Specify default and protocol-specific 802.1p/Q settings.
(boot server)	sip.cfg	• For more information, refer to Ethernet IEEE 802.1p/Q
		<ethernet/> on page A-50.
Local	Web Server	Specify 802.1p/Q settings.
	(if enabled)	Navigate to http://<phoneIPAddress>/netConf.htm#qo
	Local Phone User	Specify whether CDP is to be used or manually set the VLAN ID or
	Interface	configure DHCP VLAN Discovery.
		Phase 1: bootRom - Navigate to: SETUP menu during auto-boot
		countdown.
		Phase 2: Application - Navigate to:
		Menu>Settings>Advanced>Admin Settings>Network

Voice Quality Monitoring

Note	This feature requires a license key for activation. Using this feature may require
	purchase of a license key or activation by Polycom channels. For more information,
	contact your Certified Polycom Reseller.
	The SoundPoint IP phones can be configured to generate various quality
	metrics for listening and conversational quality. These metrics can be sent
	between the phones in RTCP XR packets. The metrics can also be downloaded
	in SIP messages to a central voice quality report collector. The collection of
	these metrics is supported on the SoundPoint IP 330/320, 430, 501, 550, 560,
	600, 601, and 650 and the SoundStation IP 4000.
