VoIP quality is typically measured using a standardized rating system called MOS (Mean Opinion Score), which rates the quality of a voice call on a scale of 1 to 5. MOS scores are calculated based on subjective ratings from human listeners who rate the call quality based on factors such as clarity, background noise, and echo.
The Mean Opinion Score, usually referred to as MOS Score, has been the most commonly-used metric to measure the overall voice call quality for decades. Standardized by the International Telecommunications Union (ITU-T), MOS Score is:
A numerical measure of the human-judged overall quality of voice and video sessions.
The MOS is obtained by having a group of people listen to a set of standardized audio samples and rate them on a scale of 1 to 5, with 1 being the lowest quality and 5 being the highest. The ratings are then averaged to obtain the MOS score.
Voice Quality MOS Score is most often judged on a scale from 1 (bad) to 5 (excellent) of the perceived quality of a voice call. Although originally Mean Opinion Scores were derived from surveys of expert observers, today a MOS Score is often produced by an Objective Measurement Method approximating a human ranking.
The MOS Score (Mean Opinion Score) for Voice Quality was originally developed for traditional voice calls but has been adapted to Voice over IP (VoIP) in the ITU-T PESQ P.862.
The standard defines how to calculate MOS Score for VoIP Quality based on multiple factors such as the specific codec used for the VoIP call. Each VoIP codec (ex: G.711, G.722, G.723.1, G.729) behaves differently. Some codecs such as G.711 are uncompressed for higher quality but use more bandwidth than compressed codecs such as the G.729.
The MOS Score we measure is for the G.711 codec, which is by far the most used codec for VoIP calls. The maximum MOS Score for a G.711 call is 4.4.
As we explained, MOS score is a key metric used in VoIP Monitoring to monitor VoIP Quality - so how do you actually monitor it?

Imagine you're on a VoIP call with a customer, discussing an important project, when suddenly your voice sounds like a robot on roller skates, with echoes that make you feel like you're talking to yourself from the future. What's going on? It's the mischievous culprit known as 'jitter'!
In the world of Voice over Internet Protocol (VoIP), jitter is the party crasher that messes with your voice packets' perfect timing. Let's dive into this wild, wobbly world of jitter and see how to keep your VoIP calls smooth and distortion-free.
Jitter in VoIP refers to the variation in the delay of packet arrival when transmitting voice data over a network. VoIP technology relies on breaking audio data into small packets and sending them over the internet or a network. Ideally, these packets should arrive at their destination at a consistent rate and with a consistent delay. However, network congestion, routing issues, and other factors can lead to variations in the arrival time of these packets, resulting in jitter.
Jitter can negatively impact the quality of a VoIP call in several ways:
- Audio Distortion: Variations in packet arrival times can lead to audio distortion, including choppy or garbled speech, making it difficult for users to understand each other.
- Echo: Jitter can also contribute to echo in a VoIP call, where users hear their own voice with a delay, which can be distracting and disruptive.
- Latency: High jitter can increase overall call latency, causing delays in conversations, which can be especially problematic for real-time communication.
To mitigate jitter in VoIP calls, various techniques are used, including:
- Buffering: VoIP devices can use jitter buffers to temporarily store incoming packets and then play them out at a more regular interval. This can help smooth out variations in packet arrival times.
- Quality of Service (QoS): Network administrators can implement QoS policies to prioritize VoIP traffic over other types of data, ensuring that voice packets receive preferential treatment and minimizing jitter.
- Traffic Prioritization: Prioritizing VoIP traffic on routers and switches can also help reduce jitter by giving voice packets priority in network queues.
- Network Monitoring: Real-time monitoring of network conditions can help identify and address issues that contribute to jitter, such as network congestion or high packet loss.
- Packet Loss Concealment: VoIP systems may employ packet loss concealment techniques to mask the effects of lost or out-of-order packets, improving the perceived audio quality during calls.
Overall, managing jitter is essential for maintaining high-quality VoIP communication and ensuring a smooth and clear voice conversation over the internet or a network.

So jitter in VoIP makes you sound like robot, now latency VoIP is a whole other demon!
Image you're on a call and suddenly there's a pause long enough to make you wonder if they've time-traveled to the future. Nope, it's just the mischievous 'latency' playing tricks on your VoIP call! Latency is the time-traveler of the digital world, adding a delay to your voice as it zooms through the Internet.
Latency in VoIP refers to the delay or lag in the transmission of voice data over a network. It is the time it takes for an audio signal to travel from the sender to the receiver in a VoIP call. Latency is typically measured in milliseconds (ms) and can have a significant impact on the quality of a VoIP call.
There are three main types of latency in VoIP:
- Transmission Latency: This is the delay caused by encoding and compressing the audio signal, transmitting it over the network, and then decoding and decompressing it at the receiver's end. While modern VoIP systems aim to minimize this type of latency, it still exists to some extent.
- Propagation Latency: This is the time it takes for the data packets to physically travel across the network infrastructure, including routers, switches, and cables. Propagation latency is influenced by the physical distance between the sender and receiver and the speed at which data travels through the network.
- Processing Latency: This refers to the time it takes for the VoIP devices (phones, computers, or servers) to process the audio data and convert it into digital packets. Processing latency can vary depending on the performance of the devices and the efficiency of the VoIP software or hardware.
Latency can have several effects on a VoIP call:
- Delay in Conversations: High latency can result in noticeable delays in conversations. This delay can be frustrating for users because it interrupts the natural flow of communication.
- Echo: Latency can contribute to echo in a VoIP call, where users hear their own voice with a delay, making it challenging to have a smooth conversation.
- Reduced Call Quality: Excessive latency can lead to call quality issues, such as choppy audio or dropped words, which can negatively impact the overall user experience.
To ensure a good VoIP experience, it's important to keep latency as low as possible. Minimizing latency is essential for maintaining clear and real-time communication in VoIP calls. Here's how!
Certainly! Expanding on how to keep latency low to ensure a good VoIP experience:
1. High-Quality Network Connections:
- High-Speed Internet: A fast and reliable internet connection with sufficient bandwidth is crucial for minimizing latency in VoIP calls. Consider upgrading your internet plan if you frequently experience latency issues.
