As more businesses and homes embrace VoIP technology, complaints of VoIP jitter are often heard. Therefore, you’ve probably wondered what jitter is, why it’s important, and how can you get rid of it.

VoIP jitter defined

Before jitter is defined, it is important to understand a bit about VoIP technology. In a VoIP System, information is divided into pieces known as voice packets. The individual voice packets travel from the sender to the receiver along unique pathways. This, in turn, means that packets can arrive at different times and sometimes even in a different order. This altered arrival sequence is jitter.

To those on the receiving end, jitter comes across as poor, garbled or delayed audio. For computers, jitter can cause display flicker, failure to perform issues and in both cases the potential loss of data.

Jitter is one of the most common complaints related to VoIP technology. Now that jitter has been defined, you probably can answer the second half of the question on your own, but let’s press on.

Why does VoIP jitter matter?

Chances are you’ve been on the receiving end of Jitter at least once (probably more, but once is enough to understand). And in that incident, you were likely frustrated, tried to communicate and probably disconnected your call to try again hoping for less jitter. Now consider this scenario in your business. You call a customer, client, or colleague (or a potential customer, client or colleague), and the receiver experiences jitter.

What kind of impression will that make for you and your company? Remember how you felt on the receiving end of your jitter call? Frustrated, annoyed and aggravated. Or suppose it’s conference call time and the conference participants experience jitter on their ends. When data is lost how will everyone communicate effectively? In all likelihood they won’t, will they?

The cause

Since jitter is basically time variations (deviation or displacement) of voice packet delivery from one system to another, a system issue is often the cause. Because jitter occurs in high-frequency digital signals, it can be caused by crosstalk from other such signals, electromagnetic interference, low bandwidth and network congestion. Jitter is problematic, but with the help of your VoIP provider it can be stopped.

The jitter solution

To eliminate jitter, businesses need to utilize jitter buffers (aka de-jitter buffers). These buffers can be installed within your network or on individual computers. Once installed, the receiving application accepts the packets from the buffer, which delivers them at a steady rate thus eliminating jitter.

Jitter can also be eradicated with VoIP networking equipment that adjusts timing issues by routing select traffic via the most stable pathways, typically the choosing the travel pathway closest to the required delivery rate.

Jitter issues can be solved; don’t let jitter come between you and your clients, customers or colleagues.
