What Is VoIP QoS and How Does It Make Your Calls Better?

Are you experiencing call quality issues, even with a solid internet connection? Then, you must optimize your business phone system with Quality of Service (QoS).

Today, 92 % of customer interactions take place over the phone. Hence, maintaining good audio quality is crucial for any organization to provide a better calling experience and enhance customer satisfaction.

Poor communication is a red flag for any customer. Customers get frustrated and dissatisfied when they face call quality issues.

So, in this blog, we’ll talk about VoIP QoS, why it is essential, its best practices, and everything you want to know about QoS. So, let’s dive right in and upgrade your call quality.

What is VoIP QoS?

VoIP QoS is a technology that helps to provide high-quality voice communication over the internet, prioritizing network traffic passing through a router.

VoIP Quality of Service (QoS) is essential to ensure high-quality and reliable communication without any communication issues.

It is crucial for any business phone system. Businesses can use VoIP QoS to provide dedicated bandwidth support to specific customer service teams, users, and events.

Additionally, they can optimize data traffic over a router to resolve audio quality issues. Overall, Quality of Service aims to minimize packet loss, latency, echo, and jitter to improve audio quality.

Why does Quality of Service matter?

Since VoIP calling relies heavily on the internet, that means it’s vulnerable to network congestion, jitter, latency, and packet loss. These issues directly affect VoIP call quality.

When voice traffic gets disrupted, you’ll hear echoes, static, or broken audio. You may even experience dropped calls. This can lead to confusion, delays, and unhappy customers. Poor call quality also damages trust and reduces team productivity.

That’s where Quality of Service (QoS) steps in. With the right QoS settings, your system prioritizes VoIP traffic. It sends important data packets first, delays the less critical ones, and uses bandwidth allocation to manage different types of traffic.

In short, QoS for VoIP helps ensure clear voice communication, improves network performance, and keeps your business calls running smoothly even when available bandwidth is tight.

Troubleshooting VoIP Call Quality with QoS

Checking the internet’s quality and speed is the first step in troubleshooting VoIP call quality issues. But it won’t necessarily fix all of the issues with call quality. So it is essential to deal with the root of the problem and offer quality service to fix it.

Here are a few steps to troubleshoot VoIP call quality with quality of service.

1. Determine the root cause of call quality issues:

Try understanding the pattern and frequency of call quality issues by taking user feedback. Find out why users face call issues like low-quality audio, echoes, choppy audio, delays, distorted sounds, and dropped calls.

2. Check network performance:

Use different network monitoring tools to check the performance of the network. Look for metrics like packet loss, latency, and jitter and then utilize the gathered information to analyze the issues and areas for improvement.

3. Configure the QoS Setting:

Ensure that the network devices, like routers and modems, are appropriately configured. Check whether the QoS is enabled on the router and configured correctly to prioritize VoIP traffic over other data types.

4. Allocate sufficient bandwidth:

Providing sufficient bandwidth to VoIP traffic helps in reliable voice transmission and prevents network congestion. So, it is always better to determine bandwidth allocation based on the expected traffic load and the number of concurrent calls.

5. Upgrade network infrastructure:

It’s not always the speed of the internet that’s causing VoIP call quality issues. Sometimes, it’s the outdated network infrastructure and hardware, like routers, firewalls, switches, headsets, microphones, etc.

So, consider upgrading the infrastructure and hardware for better transmission of VoIP traffic and minimizing frequent call quality issues.

6. Regularly monitor and adjust:

Regularly monitoring the network performance helps to determine high-quality VoIP calls. You can use the user’s feedback and real-time performance data to adjust QoS settings.

Recommended VoIP QoS settings

VoIP QOS setting is a network management tool that helps manage the data flow on a network, allowing precise and reliable voice transmission of data packets.

The following are some recommended QoS settings and considerations:

• Activate QoS: Activating QoS on network devices like routers and switches is the initial step of the QoS setting.
• Prioritize VoIP traffic using QoS: Prioritize VoIP traffic using QoS, which allows voice packets to be transmitted to end users with better quality.
• DSCP (Differentiated Services Code Point): Use DSCP to prioritize VoIP traffic.
• Jitter Buffer Configuration: To reduce the impact of jitter on call quality,
• Packet Loss Handling: Use Forward Error Correction(FEC)or redundant packet transmission to address packet loss issues.
• VoIP bandwidth allocation: Provide adequate bandwidth for VoIP traffic. Ensure enough bandwidth is allocated for voice calls without affecting other data activities.
• Traffic Classification: Configure your QoS settings to classify VoIP traffic as real-time or voice. This way, routers and switches can identify and prioritize voice packets accurately.

How to Set Up VoIP QoS?

Setting up VoIP QoS is essential for smooth voice communication, AI voice, and even video conferencing. The process may differ depending on your VoIP service provider, such as United World Telecom or others, but the basic steps stay the same.

Here’s how to do it right:

1) Check your network.

Know your available bandwidth, network devices, and current data traffic flow.

2) Enable QoS on your equipment.

Access routers or switches that support Quality of Service (QoS) and activate it.

3) Identify your VoIP traffic.

Tag voice traffic, VoIP packets, and AI voice data to be prioritized.

4) Use DSCP and Expedited Forwarding.

Apply Differentiated Services Code Point (DSCP) with Expedited Forwarding (EF) to give voice packets the highest priority.

5) Prioritize traffic.

Set your QoS settings to prioritize voice, business VoIP, and video conferencing, ahead of other types of traffic.

6) Limit non-essential bandwidth.

Use traffic shaping to stop downloads or background apps from using too much bandwidth.

7) Add jitter buffers.

Help prevent call quality issues like echo or delay on your VoIP phones.

8) Test and monitor.

Run test calls. Use monitoring tools to detect packet loss, network congestion, or dropped calls.

VoIP Call Quality Best Practices

For making the best quality VoIP calls, here are some practices:

1. Allocate Sufficient Internet Bandwidth

For high-quality VoIP calls, you must have a stable and high-speed internet connection, which provides sufficient bandwidth for data packet transmission.

According to industry standards, users should have a minimum of 1 Mbps upload and download speed to perform a call without any issues.

2. Use wired Ethernet connections

A slow or unstable WIFI connection decreases the quality of your call, so you should use an Ethernet cable instead. With an Ethernet cable, you can avoid the risk of a bad termination.

3. Prioritize VoIP Traffic

Using Quality of Service (QoS) settings on routers to prioritize VoIP traffic over other internet activities is the best practice for VoIP call quality. By prioritizing VoIP traffic, it provides the necessary bandwidth to perform high-quality calls.

4. Select a Reliable VoIP Service Provider

Many VoIP service providers are in the market, so look for a reputable VoIP service provider that provides quality and reliable service. Also, check out the provider’s network infrastructure and research reviews of the user.

5. Use High-Quality Equipment

Investing in high-quality VoIP phones like headphones, microphones, and routers is also a best practice to provide better call quality. Ensure that the equipment you use with your VoIP service is up-to-date and compatible.

6. Monitor network connection regularly

Monitor the network connection, and make sure your service provider provides the internet speed as promised. Monitor your ping, jitter, and latency to avoid all the connectivity issues and enjoy better call quality.

What Are The Limitations Of QoS?

Quality of Service (QoS) is a powerful way to manage network traffic. It prioritizes VoIP traffic, helps reduce packet loss, and optimizes call performance. But it’s not a magic fix for everything.

Let’s break down the real limitations of QoS.

1. Dependent on the Internet

On public networks, especially during peak hours, network congestion can still cause jitter, latency, and dropped calls.

That means even with QoS in place, voice calls may suffer. This is especially true if you’re not using a dedicated business phone system.

2. Fully Dependent on Network Congestion

QoS works by allocating bandwidth for VoIP. But if your network devices are already overloaded, there’s only so much it can do.

Limited available bandwidth means QoS can’t fully prevent call quality issues, even when it prioritizes network traffic. In short, bandwidth limitations will still affect VoIP call quality.

3. Complex Configuration

Setting up VoIP QoS isn’t easy. You’ll need to understand QoS settings, traffic shaping, and types of traffic. One wrong move can mess with your network performance or block important voice data.

That’s why many businesses use monitoring tools or hire IT experts when setting up VoIP.

4. Dependent on Network Equipment

QoS settings rely on compatible network equipment like routers, switches, and firewalls. Older or misconfigured devices can block voice packets or fail to prioritize voice properly. It fails to deliver during the power outage as well.

To truly improve VoIP, your hardware must support quality of service QoS features like differentiated services code and jitter buffer management.
