You might have noticed choppy sound or missing words during a call. This is a sign your VoIP system is experiencing packet loss. Many people feel frustrated when calls break up or drop out, and packet loss can lead to a less than acceptable call quality, but there are steps you can take to fix these voip issues, and make your calls clearer.
At Zexi, we understand how important it is for every team member to communicate easily and your voip services should suit your specific requirements no matter where you work. Settling for an acceptable level is not ideal, and whilst users have different tolerance levels on what is considered acceptable for a particular service, high packet loss can cause frustration for the users, and result in poor call quality. Keeping your conversations sharp is what makes teamwork smooth. If you want your VoIP calls to sound better, let’s look at how reducing packet loss would improve voip quality and keep voices clear.
What Is VoIP Packet Loss?
Packet loss occurs when data packets do not make it from one place to another during a voice over internet (VoIP) call. Packet loss can make pieces of sound or data disappear, and this can cause your call to break up or even drop completely.
Why does packet loss occur? Well, data travels across networks in small chunks. If your network is busy, unstable or poorly set up, packets are lost or delivered late. A higher packet loss rate in VoIP traffic will result in poor audio and more complaints about call quality. There are steps you can take to prevent packet loss and voip monitoring will enable your provider or IT to identify and troubleshoot packet loss issues, see the amount of packet loss and fix issues that may not otherwise be visible..
Causes of Packet Loss in VoIP Calls
Packet loss in VoIP calls can stem from a variety of sources, often related to problems with the network performance and infrastructure. Understanding these causes is essential for identifying the source of the packet loss and addressing issues to ensure clear and reliable communication. Whilst eliminating packet loss completely is not always an option, packet loss monitoring tools will measure packet loss and enable you to identify software issues, or issues with network and the applications installed.
Network Congestion
Network congestion is one key cause of packet loss. When too many devices are using your network at once, bandwidth gets tight. Imagine a road jammed with cars – things slow down, and some may not get through in time. The same thing happens with your data packets. More traffic means more chance of dropped packets and poor call quality.
Network congestion is common in busy offices or homes with lots of devices. Simple tasks like a file transfer or video streaming can crowd the network. If your VoIP calls share bandwidth with these activities, you may notice higher levels of packet loss. Keeping an eye on network traffic helps detect packet loss and avoid congestion before it causes problems.
Hardware Limitations
Outdated network devices can also cause packet loss. Basic routers and switches may not handle lots of VoIP traffic. If your device struggles with the load, it drops packets or slows them down, which can lead to poor call quality.
Sometimes, even the headsets or VoIP phones themselves create problems. Cheap or faulty hardware can’t process data quickly, especially during busy times. Zexi recommends investing in quality network infrastructure and reliable VoIP hardware to reduce packet loss.
Software Misconfigurations
If your network or VoIP system is not set up correctly, you can suffer from packet loss too. When Quality of Service (QoS) settings are missing or incorrect, VoIP calls have to compete with every other type of network traffic. This makes it harder for voice data to get where it needs to go.
Other misconfigurations, like firewall settings or outdated firmware, also cause problems. Small errors in your setup can lead to a high level of packet loss and poor call quality. Careful troubleshooting and regular checks are key to a stable VoIP call experience.
Why Packet Loss Affects Call Quality?
Packet loss has a big impact on VoIP calls. If packets are lost, bits of your audio and video never arrive. This makes voices sound robotic, causes jitter, or leads to completely dropped calls. Low packet loss rate may only be noticed as a slight inconvenience, but most companies could and should not tolerate a higher packet loss rate, brings more problems.
Calls may become hard to follow or frustrating. A packet loss can also cause hearing echoes or silence where someone should be talking. All of this is because lost packets can’t recover, and the level of packet loss decides how bad things get. The main goal is to reduce packet loss so your conversations remain clear.
Impact on UK Businesses and Remote Workers
For UK businesses, especially those with remote teams, packet loss can cause major headaches. When a call drops or sounds broken, you might miss out on key client details or misunderstand work instructions.
Bad call quality hurts teamwork and productivity. It can even damage the trust your customers have in you. If you’re managing a remote team, stable VoIP calls give everyone a fair chance to speak and be heard. This is why UK workplaces now focus on tools and habits to fix packet loss and keep communication sharp.
Steps to Diagnose VoIP Packet Loss
To fix packet loss, you need to detect where and why it happens. Start by checking whether every call faces the same issue, or if it’s only in certain rooms, times, or devices. Providers and installation companies such as Zexi will offer support facilities to provide this service to you following your installation, ideally a rate of less than 1 % is considered a small packet loss, which is an acceptable packet loss rate, and your provider and IT should be keen to ensure they don’t let packet loss cause quality issues.
Look for patterns. Monitor call quality and see if network congestion lines up with dropped packets. Sometimes, packet loss occurs randomly, making it a challenge to figure out the true cause of packet loss. Once you know where loss occurs, you may be able to troubleshoot with the right tool or support.
Tools for Monitoring Packet Loss
Monitoring packet loss effectively requires the right tools to pinpoint issues and address them efficiently. These tools can help analyze network performance, identify weak points, and ensure smooth communication across devices and networks. Below is a list of essential tools to consider.
Ping and Traceroute
Ping and traceroute are basic, built-in network tools. You can ping another device to see if data packets make it there and back. If packets are lost or delayed, ping results show it. Traceroute gives you the exact path data follows across the network, making it easier to spot bottlenecks or drops.
These tools are good for a quick check. They don’t give loads of details for VoIP-specific problems, but help you see how reliable your connection is. If you spot lost packet messages, it’s time to dig deeper.
VoIP-specific Diagnostic Software
Some apps are designed to watch for VoIP packet loss, jitter, and latency. These solutions often come with dashboards to show packet loss rates and alert you if the level of packet loss goes up.
VoIP diagnostic software can run real-time tests to measure poor call quality or drops, so you know exactly when and where the cause of packet loss is found. This makes troubleshooting more precise, saving time and effort.
Network Monitoring Platforms
Network monitoring tools give you the full picture. They track all network traffic, spot when bandwidth gets low, and alert you if congestion may cause packet loss.
Monitoring platforms often include packet loss monitoring and analysis features meant for business. This means you get reports, visual maps, and long-term summaries to catch trends and fix issues. Zexi supports clients in setting up the right monitoring tool for the type of network they use.
How to Reduce VoIP Packet Loss?
Fixing packet loss can even remove bottlenecks and wireless interferences in your network. Start by cutting down extra use during important calls to reduce congestion. If you run loads of applications at the same time, close them or adjust settings so that VoIP gets more attention.
Use VoIP traffic settings that focus transmission power on calls. If packets are lost or delayed, try changing equipment locations or updating software. The right mix of steps can reduce packet loss and improve call quality fast.
Optimising Your Network for VoIP
VoIP technology offers flexibility and cost efficiency, but it relies heavily on a well-optimized network to perform seamlessly. To ensure clear calls and reliable connections, it’s essential to fine-tune your network settings and address potential challenges efficiently.
Upgrade Bandwidth
Having enough bandwidth is crucial for VoIP. Not all internet packages are equal. Slow speeds or too many users will result in poor audio calls or lag, especially during peak hours.
Upgrade to a faster plan or split your network if needed. This gives VoIP calls a clear route and lets you fix packet loss before it’s a real problem. Depending on the type of work you do, more bandwidth can boost audio and video reliability.
Implement Quality of Service (QoS)
Quality of Service, or QoS, is a rule you set on your router or network. It tells the system to make voice and video traffic a priority.
By setting QoS, VoIP calls jump ahead in line, so data packets don’t get stuck behind big downloads or streaming. Qos settings help reduce jitter and latency, making VoIP calls much clearer.
Use Wired Connections
Wireless networks drop packets more often. If possible, use a wired connection for important VoIP calls. Ethernet cables deliver a steadier signal, so there’s less room for loss or interference.
Wired connections are also less likely to suffer when there are lots of users. That stable path keeps calls clear even when network traffic is busy.
Choosing Reliable VoIP Hardware
Selecting the right VoIP hardware is crucial for ensuring clear communication and reliable performance. From headsets to routers, having dependable equipment minimizes disruptions and enhances call quality, making it easier to stay connected.
High-quality Routers
Routers are the heart of your network. A good router supports VoIP optimisations and handles lots of data packets without slowing down.
Look for routers built for business use, not just basic home models. High-quality routers drop fewer packets and make sure voice traffic gets priority. At Zexi, we guide clients to the right products based on their needs.
VoIP-compatible Headsets
Audio gear matters as much as your network. VoIP-compatible headsets provide better sound and cut down on echo or static. Cheap or poorly designed headsets cause problems, even when your network is fine.
Aim for models designed for VoIP systems. These convert your voice clearly and are comfortable enough for long calls, keeping you focused instead of frustrated.
Selecting a UK VoIP Provider
Not every provider is the same. Pick one that understands UK network challenges and offers service-level agreements (SLAs). This makes sure your calls stay reliable and support is quick if there’s a problem.
Zexi believes strong partnerships with the right VoIP provider are essential. The right partner can fix packet loss quicker and offers the support your business needs.
Best Practices for Maintaining Clear VoIP Calls
Stay proactive. Do regular checks to make sure your system is running smoothly. Watch for patterns that show when packet loss happens most.
Have a clear plan for troubleshooting. Make it easy for team members to report poor call quality or dropped calls. The faster you react, the easier it gets to detect packet loss and correct problems before they affect everyone.
Regular Network Maintenance
Regular network maintenance is essential for ensuring the consistent performance and reliability of your VoIP system. By taking a proactive approach, you can minimize disruptions, improve call quality, and address potential issues before they escalate.
Update Firmware
Always keep your network devices up to date. Updates fix bugs, improve speed, and can even add new tools to help reduce packet loss.
Set reminders to check for firmware updates on routers, switches, and phones. Ignoring updates can cause problems to come back again.
Monitor Network Traffic
Keep track of what’s running on your network. Use tools that show if anyone is doing something heavy, like big file transfers, that could impact VoIP calls.
Regular monitoring lets you spot and fix issues before they lead to poor call quality or lost customers.
Training for Remote Teams
Teach your remote workers how to spot problems. Show them how to test connections, switch to wired if needed, and report call quality issues. When everyone knows what to look for, it’s easier to keep calls clear.
You may be able to fix problems much faster if your team understands the basics of what causes packet loss and the steps to take.

FAQs
What are the common symptoms of VoIP packet loss during calls?
When packet loss happens during a VoIP call, you’ll notice problems right away. People sound robotic, voices cut in and out, or you hear long silences where someone should be speaking. Sometimes, entire sentences are missing. Other signs are calls that drop unexpectedly or audio that lags behind. The higher the packet loss rate, the more likely these issues will appear. Watching for these signs can help you fix packet loss sooner.
Can VPNs worsen VoIP packet loss, and how can businesses bypass this for call traffic?
VPNs can increase the risk of packet loss in VoIP calls. That’s because adding a VPN means your data has to travel further and sometimes through slower or overloaded servers. This increases latency, raising the chance that packets are dropped or arrive late. To bypass this, businesses can set up split tunnelling, letting VoIP traffic go straight over the regular network instead of through the VPN. Using this method, you reduce packet loss and ensure smoother calls. Always check with your IT team before changing these settings.
Are there specific firewall settings to improve network performance for VoIP calls in the UK?
Yes, firewall settings play a big part in VoIP call quality. You should set rules that give VoIP traffic priority and make sure no important ports are blocked. Blocking the wrong ports can stop data packets from getting through, causing call drops or lag. It helps to allow protocols like SIP and RTP and use settings designed for voice over internet use. If you’re unsure, ask your IT provider to review your firewall for VoIP needs. This simple step may be able to fix packet loss and keep your calls clear.
