In computer networks, a propagation delay refers to the amount of time taken for the head of a signal to travel between the sender and the receiver. There are three types of delay likely to occur in VoIP networks: You may recognize latency if you have ever heard an echo on a VoIP phone call or been on a Skype video-chat session where the words you hear are out of sync with the movement of the speaker’s lips. Sometimes called VoIP delay, VoIP latency is characterized by the length of time it takes for sound to exit the speaker’s mouth and reach the listener’s ear. VoIP latency is a common cause of low call quality. Recognizing the differences between the following causes will help you identify which of them are responsible for the specific VoIP issues facing your business. Now that you understand what causes jitter, let’s take a look at what else might cause low VoIP call quality. When VoIP jitter is especially high, VoIP sound quality can be so distorted communication may well become impossible, with whole chunks of the conversation going missing or being uninterpretable. In practice, network jitter on a VoIP call results in words and sentences becoming jumbled or going missing entirely. It’s caused by the division of information passing through the call into packets: each packet can use a different route to travel between the sender and the receiver, which means the packets end up in the same place, but in a different order than originally sent out. High VoIP jitter is one of the most common reasons for VoIP call quality issues. ![]() Jitter is also referred to as “stuttering” or “ping spikes.” What Causes Jitter? Delay refers to how long a packet takes to travel from one endpoint to another, and packet loss is the failure of one or more packets to get to their destination. It’s important to understand the meaning of “delay” and “packet loss,” as these terms will come up in this guide. Latency, in turn, is defined as the time taken for one packet of data to pass along its route. The technical definition of VoIP jitter is the variability over time of the network latency. ![]() If you imagine the IP network is a road, VoIP jitter is essentially road congestion caused by too many cars. Network jitter is congestion generated by millions of internet connections-tiny packets of data trying to use the same IP network-all active simultaneously. It’ll also recommend SolarWinds ® VoIP & Network Quality Manager (VNQM) as a tool for jitter monitoring, and provide an outline of the software’s most notable features ( skip to VNQM description). This guide will help you understand VoIP jitter, what causes jitter, how to measure network latency and jitter, and how to reduce jitter in VoIP. Like network performance complications, network jitter walks hand in hand with delay, latency, and packet loss.įor a network administrator, measuring network jitter and knowing how to conduct a ping jitter test is an important part of their role. For companies depending on calls to land customers or maintain healthy business relationships, a poor-quality VoIP call can have a significant impact on customer satisfaction, the ability to close sales, and ease of communication between key parties. Network jitter is a frustrating but common occurrence, and it can make the difference between a successful Voice-over Internet Protocol (VoIP) phone call and a failed one.
