4.5 Audio Quality Issues and VLANs

The phone contains both network layer and Ethernet layer support for prioritizing voice and signaling traffic over the network. Quality of Service (QoS) parameters include IP type-of-service (TOS) bits, and Ethernet IEEE 802.1p user priority. These can be set on a per-protocol basis. The phone also supports RTCP per RFC 1889.
