How to solve common VoIP call quality issues

Understanding VoIP Call Quality

Efficient and quality communication is vital for today’s fast-moving businesses where the philosophy seems to be, “Move it or lose it.”. For this reason, many companies rely on VoIP technology to connect with clients, customers, and colleagues across the globe. 

A well-optimized VoIP phone system can be a game-changer for any business. It is fast, reliable, and secure. It enhances productivity and improves the customer experience. However, despite its many advantages, some VoIP users can experience challenges with audio quality. 

VoIP sound quality is a crucial aspect for any company. It refers to the clarity, reliability, and overall performance of audio during calls. To ensure higher Mean Opinion Score (MOS) ratings and reduce miscommunication or frustration there are several key factors users can modify to solve common VoIP issues such as latency, jitter, and packet loss. 

Let’s dive deeper!

Solving common VoIP Call Quality Issues

Call quality issues can be frustrating, especially when they disrupt important conversations and conversions. Thankfully, there are easy solutions to these common issues, so you can experience crystal-clear audio, allowing for seamless and uninterrupted communication. Of course, our 101VOICE support is here to diagnose any issue you might have.

Quality of Service (QoS) Optimization

Maintaining seamless and clear conversation is paramount when using a VoIP system. But it just won’t happen if your Quality of Service (QoS) isn’t optimized. QoS refers to your network’s ability to prioritize VoIP traffic, guaranteeing a smooth flow of data and minimal latency. Without proper QoS, your calls may become distorted or experience lag. 

Our suggested solution: Configure your routers and switches to allocate bandwidth effectively for VoIP calls. By assigning priority to VoIP traffic over other data on your network, your calls will get the resources needed to remain crisp and uninterrupted. 

Dealing with Audio Quality (VoIP) Problems

Audio quality problems may include distorted sound, echoing, and other difficulties. Sometimes these issues can result from your microphone or speaker setup or using low-quality equipment. 

Our suggested solution: Check for audio clarity and ensure that your microphone and speaker settings are optimized for VoIP calls. Investing in high-quality headsets and equipment is also essential for optimal sound transmission.  

Tackling latency

Network latency, or the time it takes data packets to travel from source to destination across your network, can be a significant problem. High latency results in delays in network communication and affects the performance of real-time applications like VoIP. Ultimately, it leads to unresponsive or poor-quality calls. 

Our suggested solution: Optimize your network settings to minimize latency, ensuring real-time communication. Also, ensure your devices have the latest firmware and software updates so they can handle VoIP calls efficiently.

Jitter and Packet Loss

Jitter is the variation in the time between the arrival of data packets, causing inconsistent sound quality. Packet loss occurs when data packets are dropped during transmission, leading to missing parts of a conversation. These culprits can disrupt the flow of your VoIP calls.

Our suggested solution: Implement jitter buffers and error correction techniques to smooth out variations in packet arrival times. Additionally, consider using a dedicated internet connection for VoIP to reduce data loss.

Resolving Dropped Calls

When a call drops, it can cause significant disruptions to important conversations. Dropped calls result from network-related issues or insufficient resources to handle call volume. 

Our suggested solution: Analyze call logs and system data to identify patterns and potential causes of dropped calls. You can also adjust your network settings or consider upgrading your internet plan to handle call volume effectively. (Check out our bandwidth availability tool if you need to upgrade your internet)
