Reduce Latency and Improve Call Quality with VoIP

Voice over Internet Protocol (VoIP) enables businesses to make phone calls using the internet instead of traditional phone lines. As such, it offers numerous benefits over traditional phone systems, including cost savings, greater flexibility, and advanced features. However, one of the most significant aspects of VoIP is the quality of calls it delivers.

Improving call quality and reducing latency is essential for businesses and individuals relying on phone systems for communication. By switching from a traditional phone system to a VoIP system, companies can ensure high-quality calls in many ways, including network optimization, equipment upgrades, and Quality of Service (QoS) configuration. Choosing a reliable VoIP provider can network is also crucial for ensuring consistent call quality. 


Understanding Latency in VoIP

Latency is one of the most common issues affecting call quality. Latency refers to the delay between when someone speaks and when the other person hears them. Several factors can contribute to latency in phone calls, including network congestion, equipment issues, and protocol issues. 

In a VoIP call, the voice data is broken into small packets and transmitted over the internet. The time it takes for these packets to travel from one end of the call to the other end is known as latency. When latency is too high, it can cause delays in conversation, making it difficult for people to communicate effectively.

There are types of latency:

  • Network: The delay caused by the physical distance between the two endpoints of a call. This can also occur when too much traffic is on the web, causing delays in packet transmission. 
  • Equipment: The delay was caused by issues with the hardware used to transmit and receive the voice data. Outdated or malfunctioning routers, switches, or other network devices can cause this. 
  • Protocol: The delay caused by the protocols used to transmit and receive the data. These issues can arise when the wrong protocol is used or when the protocol is not configured correctly. 

Ultimately, latency can significantly impact call quality. However, the effect of latency on call quality can vary depending on the severity of the latency. In some cases, latency can cause delays in conversation and make it difficult for people to communicate effectively. In more severe cases, latency can cause choppy or garbled audio, dropped calls, and other issues that can significantly impact the user experience.

Understanding latency is essential for improving call quality in your phone system. By identifying the latency affecting a call and addressing the underlying issues, businesses and individuals can ensure that their VoIP calls are high quality and enable effective communication. 


Factors Affecting Call Quality 

Several factors affect call quality, including bandwidth, jitter, packet loss, and latency. To optimize call quality and reduce latency, it's essential to consider these factors and implement best practices for VoIP optimization.


Bandwidth is the amount of data transmitted over a network connection at a given time. In VoIP, insufficient bandwidth can cause call quality issues such as dropped calls and poor audio quality. While VoIP calls do not require a lot of bandwidth, it's essential to have sufficient bandwidth for the number of concurrent calls being made and consider all the other network applications using bandwidth to optimize call quality. 


Jitter is the variation in the delay between packets arriving at their destination. In VoIP, jitter can cause audio disruptions and delays in conversation. To reduce jitter, it's vital to ensure that the network connection is stable and consistent and that there's enough buffer space to compensate for variations in packet arrival times.

Packet Loss

Packet loss occurs when packets of data are lost during transmission. In VoIP, packet loss can cause audio disruptions and drops in call quality. Optimizing network settings, including reducing congestion and prioritizing VoIP traffic over other data types, is vital to minimize packet loss.


As discussed in the previous section, latency is a critical factor affecting call quality in VoIP. To reduce latency, optimizing network settings, upgrading equipment if necessary, and configuring Quality of Service (QoS) settings to prioritize VoIP traffic over other types of data is essential.


Improving Call Quality with VoIP

To improve call quality with your phone system, there are several best practices that businesses and individuals can follow–even after switching to a VoIP system. These include network optimization, equipment upgrades, QoS configuration, codec selection, and jitter buffering. 

Optimizing the network involves ensuring sufficient bandwidth, prioritizing VoIP traffic, and using QoS protocols to manage traffic. Equipment upgrades can help eliminate latency and packet loss caused by outdated or malfunctioning hardware. QoS configuration can prioritize VoIP traffic over other types of traffic, while codec selection can balance bandwidth usage and call quality. Jitter buffering can smooth out variations in packet delay while optimizing packet size, and using RTP header compression can reduce latency and improve call quality.

By implementing these best practices, businesses and individuals can ensure that their VoIP calls are high quality and enable effective communication and collaboration. The benefits of improved call quality with VoIP include clearer audio; fewer dropped calls, and a better overall user experience. This can lead to increased productivity, better customer service, and higher satisfaction among employees and customers.

In addition to following these best practices, businesses and individuals should consider working with a VoIP provider who can offer additional support and resources to improve call quality and, if there is an issue, help pinpoint root causes. A VoIP provider can provide tools and services such as network monitoring, QoS scoring for calls, troubleshooting, and support, which can help businesses and individuals identify and address call quality issues.

Benefits of Reducing Latency and Improving Call Quality

In addition to simply improving communication with your customers, reducing latency and improving call quality with VoIP offers businesses numerous benefits, including:

  • Enhanced user experience: Reducing latency and improving call quality can create a more seamless and natural conversation experience. Users can communicate effectively without delays, echoes, or disruptions, enhancing the overall user experience.
  • Improved productivity: Clearer and more reliable communication can lead to improved productivity. Employees can communicate more efficiently and effectively, increasing collaboration and faster decision-making.
  • Better customer service: VoIP systems are widely used in customer service departments. Reducing latency and improving call quality can help customer service representatives communicate more effectively with customers, leading to better customer satisfaction.
  • Cost savings: Improving call quality can lead to fewer dropped calls and improved efficiency, resulting in business cost savings.
  • Competitive advantage: With more businesses relying on remote work and collaboration, having a high-quality VoIP system can provide a competitive advantage in the marketplace.

Partnering with a VoIP provider like Simplicity can help businesses obtain the benefits of reducing latency and improving call quality in several ways. Simplicity VoIP offers robust network infrastructures designed to handle VoIP traffic, providing dedicated network connections and configuring network settings to prioritize VoIP traffic, reducing latency and improving call center technology.
