◇ Jitter / Packet Loss / Delay
- Excessive jitter can result from congestion on LANs, Access Links, low bandwidth WAN links/trunks or the use
of load sharing. High levels of jitter cause large numbers of packets to be discarded by the jitter buffer in the
receiving IP phone or gateway. This may result in severe degradation in call quality or large increases in delay.
- Packet loss is the failure of one or more transmitted packets to arrive at their destination. This event can cause
noticeable effects in all types of digital communications.
- VoIP delay or latency is characterized as the amount of time it takes for speech to exit the speaker's mouth and
reach the listener's ear. Latency sounds like an echo.
