VoIP Jitter: Know-How to Test, Measure, & Reduce

Nobody likes to get interrupted in-between tasks or calls, especially when having a client on call. However, sometimes the call drops on its own, or your voice starts cracking up. This all can happen due to jitters in your VoIP network. So the question is what actually jitters are? Let’s Discuss every aspect of jitter that can affect your business and ways how to detect and prevent them in detail further:

What are Network Jitters?

In VoIP networks, the information is transferred over the internet in the form of data packets from your computer. These packets take a certain amount of time and transfer at regular intervals. Jitters cause delay or interruption in the transmission of these packets in your connections. An organization is required to suspect and prevent these jitters from having interrupted call experience over the internet. The higher delay or interruptions in data packets’ transportation, the inferior the quality of video and audio transmissions. 

How to Conduct Test & Measure Network Jitters?

In order to measure the network jitters, you need to calculate the delay in transmission of data packets accurately. In persistent online communication, it is relatively easier to measure the delay in the network. However, all types of jitters cannot be detected in the same way. Luckily, business VoIP service providers can test and measure the VoIP jitters beforehand and solve your network’s issues. 

These service providers will check jitters based on the network traffic, and the method will completely depend on the types of access you have on the endpoints of the network. Ping jitter test is used if you have access to only one endpoint of the network. Otherwise, the instantaneous jitter measurement can be used. 

Ways to Reduce Jitters in VoIP

  • Prioritize Packets

When looking for ways to reduce jitters, you can check the quality of service settings. You can prioritize packets that require more attention over the types of traffic and can reduce hindrance. If your VoIP system is lapsing because of traffic congestion, then prioritizing packets will surely help.

If you believe that your internet calls are more important than other areas of traffic, then it is the best option. For instance, if your business operations run solely on VoIP to make calls to customers, prioritizing packets can bring optimal results for you. With having no jitters, you can engage with your clients over video or audio conferencing without any embarrassing or unnecessary interference.

Many business VoIP service providers offer a wide range of benefits in customer support for organizations that count on VoIP beyond HD-voice phone calls.

Extend a Jitter Buffer

Throughout a single call over VoIP, jitters in the network can differ in degree. Installing a jitter buffer device can help reduce the problem. In case the range of jitter reaches an acceptable threshold limit, you can deploy the buffer, which will counter latency and delay.

When we install a jitter buffer, any voice packets that enter the network are then stored for a short period for a purposeful delay. It is generally configured for a delay of 30 to 200 milliseconds prior to reaching the end-user. This whole process ensures that the data packets arrive at the end-user properly without any further delay. 

  • Test Bandwidth Of Network

Testing the bandwidth of the network is the best way to find out if your rising jitters are caused by your internet services provider or otherwise. In order to perform the test, you will be required to plug in your PC or laptop directly with the internet modem. If you are not able to do this, your VoIP provider can help you resolve the jitter problems.

If you don’t find any problem in the test and your VoIP calls still drop, contact your business VoIP services provider to troubleshoot the issue.
