4.5.1 IP TOS
The “type of service” field in an IP packet header consists of four TOS bits and a 3-bit
precedence field. Each TOS bit can be set to either 0 or 1. The precedence field can
be set to a value from 0 through 7. The type of service can be configured specifically
for RTP packets and call control packets, such as SIP signaling packets.
4.5.2 IEEE 802.1p/Q
The phone will tag all Ethernet packets it transmits with an 802.1Q VLAN header
when it has a valid VLAN ID set in its network configuration, or is instructed to tag
packets via Cisco Discovery Protocol (CDP) running on a connected Ethernet switch,
or a VLAN ID is obtained from DHCP (see 2.2.1.2.2 DHCP Menu on page 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.
