Five Simple Ways to Troubleshoot Poor Phone Call Quality

One thing the past twenty years has taught us is anyone can learn the basics of technology usage. Putting “Microsoft Office Proficient” on a resume is now a mandatory skill rather than a bonus one, almost anyone can operate a computer, and you can no longer make jokes about older generations having trouble with television inputs.

The saturation of technology in our daily lives has not made us better at troubleshooting, however. Troubleshooting an issue alone can be so frustrating that the average consumer will pay money to have IT personnel perform even the most basic steps.

Your company doesn’t have to waste its money on basic phone call quality troubleshooting. These five essential troubleshooting steps will save you time and money – and even if they don’t provide an answer to the issue, they’ll get you closer to a solution.


How to troubleshoot bad phone call quality

Step One: Monitor Your Bandwidth

Companies that use VoIP often experience bandwidth-related phone call quality issues. Bandwidth refers to the rate that data can be transmitted across a certain path (or band). It is the backbone of internet-based communication.

Lower bandwidth means it will take more time to transmit data from one point to another, and a drop in bandwidth can lead to issues with call quality. Monitoring your bandwidth can help diagnose the problems with your voice quality or rule it out as a possible cause.

Step Two: Check Your Firewall

If your IT department set up a firewall for your network, have them double-check that it is not causing any call quality issues.

Firewalls are typically set up to prioritize network traffic for VoIP systems. However, they can sometimes cause problems if they are not set up correctly in the first place or if they are reset at any point.

Step Three: Inspect Equipment Regularly

Phone call voice quality issues aren’t always hyper-technical. Sometimes, a simple inspection of essential office equipment can be telling.

Once every month or so, perform routine inspections of your employee workspaces. Be sure that headsets are functioning correctly, as well as other phone components. Additionally, check smaller things like cords. Even the most minor crack in a cord can make a difference in sound quality.

Step Four: Reset Your Router and All Computers

You’ve likely heard a member of your IT crew say, “turn it off and on again” about your computer or phone. Don’t just shake your head at this – it really is a significant first step to take when you experience repeated VoIP technical issues.

Just as you might shut down your computer at the end of the day so that it gets better long-term performance, restarting your router gives it a break and often improves call quality overall.

Step Five: Configure Your Network to Prioritize VoIP

If you’ve switched over from landline to VoIP in the past few years, your network is probably set up to prioritize VoIP. Still, it doesn’t hurt to check.

Your network should prioritize VoIP connections over all other connections for the best service. Have a network set up solely for incoming and outgoing calls, and one set up for other internet activities. Doing this will prevent call quality from decreasing due to unexpected network traffic.

Final Thoughts

These steps are not time or labor-intensive. However, they can save your company time and money in the long run.

Be sure to record every troubleshooting step you take, including how you do it. Though tedious, these steps will help any IT specialist you contact to understand the nature of the problem.
