Quality of Service (QoS)

VoIP is extremely bandwidth and delay-sensitive. QoS is a major issue in VoIP implementations, regarding how to
guarantee that packet traffic is not delayed or dropped due to interference from other lower priority traffic. VoIP can
guarantee high-quality QoS only if the voice and the SIP packets are given priority over other kinds of network
traffic. The phones support the DiffServ model of QoS.
Voice QoS
In order to make VoIP transmissions intelligible to receivers, voice packets should not be dropped, excessively
delayed, or made to suffer varying delay. DiffServ model can guarantee high-quality voice transmission when the
voice packets are configured to a higher DSCP value.
SIP QoS
The SIP protocol is used for creating, modifying, and terminating two-party or multi-party sessions. To ensure good
voice quality, SIP packets emanated from the phones should be configured with a high transmission priority.
DSCPs for voice and SIP packets can be specified respectively.
Note
: For voice and SIP packets, the phone obtains DSCP info from the network policy if LLDP feature is enabled, which
takes precedence over manual settings. For more information on LLDP, refer to
