Cisco Jitter

If you’ve come across this article, you’re likely experiencing some problems with your Cisco products. Well, in this article, we’ll focus specifically on the common problem of Cisco jitter, highlighting why it happens and some effective steps you can take to fix it.

In short, Cisco jitter is a telecommunications term used to quantify the packet loss of data packets. Cisco jitter is an important factor in determining the quality of a VoIP call.

What is jitter?

Jitter or packet loss occurs when packets of data aren’t received by the destination (or when they’re received out of sequence). When packets arrive too late or too early to their destination, they’re considered lost.

Jitter is an important factor in determining the quality of a VoIP call, and you’ll need to keep it under control to achieve uninterrupted voice and high-quality video streaming. Essentially, when jitter occurs, call quality suffers.

Packet loss can result from a range of factors, including high latency, poor quality network connections, congested networks, or other disruptions in data transmission. 

Now we’ve discussed what jitter is, we’ll offer some tips on identifying and solving the problem promptly.

Symptoms of Cisco jitter

As we discussed above, jitter is a common problem Cisco systems experience. It’s crucial to understand how to identify symptoms of packet loss to rectify them.

Some common symptoms of Cisco jitter include:

  • Loss of voice on VoIP calls
  • Intermittent video quality on a video conference
  • Slow surfing speed
  • Internet connectivity issues

Here’s a quick example of how Cisco jitter can occur. When one computer on your office network is downloading a large file while another tries to use Skype, there are chances that network slowdowns will occur due to insufficient bandwidth.

Best ways to fix Cisco jitter

In this section, you’ll find some simple troubleshooting tips for fixing Cisco jitter and packet loss issues.

  1. First, check for any Cisco equipment or software updates. Updates are often designed with fixing bugs and solving issues in mind. Regularly check for updates to avoid packet loss issues and keep your systems running smoothly.
  2. Next, disable any QoS settings on your network. You can achieve this by going into the control panel on your computer and disabling QoS altogether—or you can disable individual applications using too many resources while still keeping some working applications on the network during testing periods.
  3. Ensure your hardware is working properly. Out-of-date or damaged routers, hubs, bridges, and switches can lead to call quality issues and jitter. Also, keep an eye out for damaged cables or bad router configurations.
  4. Congestion is a leading cause of packet loss and call quality issues—so to avoid stretching your bandwidth beyond its limits, make sure not to run too many devices on the same network


Cisco jitter is a common problem, but thankfully, there are some simple fixes. With the troubleshooting tips you now have under your belt, you should have no trouble fixing jitter and packet loss issues that crop up in the future.
