Deterministic: P redicted or determined, this is reproducible, limited, and it may be periodic.Random: Also referred to as “Gaussian jitter”, this has unpredictable electronic timing noise usually resulting from clock timing problems or random electronic timing noise.Whether they come in interspersed intervals with holes, or if they appear out of order, then you’ve got a high jitter. When they appear in the right series in a good steady stream at regular intervals then you’ve got low jitter. It is more about pacing and a series of RTP packets that are coming in. According to Cisco, 30ms is the acceptable amount of jitter time for a customer. We often tend to ‘drop the call’ and quickly try to reconnect straight away.

Jitter can cause many participants to leave the phone call and either attempt to re-establish a connection or move to another form of communication. Packet switching networks do not ensure that packets travel the same path to their destination.Īnother common and equally frustrating annoyance that affects phone calls is jitter. A cousin to latency, jitter refers to packet delay variation carrying voice or video data over a communications channel. Jitter happens when the RTP packet stream traverses the network (LAN, WAN, or Internet) because it has to share network capacity with other data. Speech data translates into packets for call participants and redirects ‘toward’ a recipient. Today, telecommunications traffic largely passes over a packet-switching network and very often over the public internet.
