What Causes Poor VoIP Quality and How Can I Fix It?

Voice over internet protocol (VoIP) revolutionized business calling. Any device with a broadband connection can make calls anywhere and improve productivity. Additionally, VoIP is easy to update, so its implementation is scalable.

And no one complains about the cost. Calls made from any phone connected to the internet actually means a cost reduction. But some people do complain about poor VoIP call quality.

See, VoIP still comes with its own, sometimes complex, problems. The good news is most problems are easily fixed with the right troubleshooting steps.

The Common Culprits: VoIP Call Quality Edition

All issues in life have a core cause. It’s not easy to determine the root of poor VoIP call quality issues when you aren’t a tech guru. Some of the common culprits behind VoIP issues include:

  • Blocked ports. Firewalls are one of the most common issues behind blocked ports. Fortunately, they are easily remedied with the help of a network administrator.

Other port blocks (ACLs and NATs) are harder to remedy. But they can be quickly addressed with the help of your network provider or a professional.

  • Equipment malfunction. There’s a reason why Roy of “The IT Crowd” consistently asked his customers if they tried turning it off and on again. Intelligently fiddling with or adjusting your equipment might make a difference.

Replace any old, broken, or outdated pieces and see if it clears up your issue. And, really, try turning it on and off again if all else fails.

  • Too much network traffic. Your phone line will ideally have its own, dedicated network so that no outside issues will influence it.

If it doesn’t? You may get poor VoIP call quality issues.

  • Software and Firmware. Keeping firmware and software up to date will ensure call clarity. It will also prevent any downtime related to system crashes or bugs that might have been addressed in an update.

  • User Error. The culprit is sometimes your staff. Be sure to give all phone operators adequate training so they know exactly what is going on when a system malfunction happens. Proper training means less calls to tech support and more money in your pocket.

Things To Consider Before Getting Mad

We’ve all experienced a moment that has set us over the edge of frustration into anger. That line doesn’t have to be crossed with your VoIP service. Take these core considerations to mind before throwing your phone at the office wall.

  • Make sure that your system can handle VoIP before switching over. Businesses that make the jump from landlines to VoIP must have a plan of action. Seamless switchover from former systems to upgraded systems is critical to long-term success.

If you don’t think your infrastructure or team is ready for a switch, work with professionals to figure out what might work best for you.

  • Upgrade your internet. Internet is a huge culprit behind poor VoIP call quality. Getting a service that provides more bandwidth is a great way to prevent phone quality issues.

  • Prioritize voice traffic over other traffic on your network. Web browsing, email, and more can impact the quality of your VoIP calls. Prioritize phone calls for the best service possible.

  • Update your equipment. It’s unlikely your phone service will be top-notch if your equipment is out of date. Internet service providers consistently update their technology. Ergo, voice quality will likely suffer if you are using outdated technology in tandem with the newest technology.

  • Work with a VoiceAPM technology. Voice Application Performance Management (VoiceAPM) services are great for dealing with all other voice-related issues you can’t figure out yourself. They will examine trends in downtime, bandwidth, network interference, and more to help you diagnose problems.

Our Best Advice

VoIP calls are heavily reliant on good internet connections. Use the checklist we made above to narrow down the root of any issues you might experience in your business.

You may need to fix your internet connection if you’ve made sure none of those core causes are the culprit. Before upgrading, however, it’s worthwhile to check in with a voice application management team to further narrow down what could be causing issues with your phone quality. Getting help from the pros saves time and money in the long run.
