PRTG makes MOS monitoring easy
Custom alerts and data visualizations make it easy to monitor, identify, and prevent background noise, bad quality of voice, and other causes of poor audio quality.
Stop "Hello?... Hello?... Can you hear me?" in its tracks, monitor MOS
We've all been on one (actually, many) of those calls.
Your video keeps freezing. Or you're constantly having to ask the other person to repeat themselves, because their voice keeps breaking up and you can't understand a word they're saying.
It's awkward at the best of times. But especially so if it's an important meeting, like a sales presentation for a big client, or a new project kick-off.
Paessler PRTG's comprehensive network performance monitoring tracks the mean opinion score and other values that could impact call quality and alerts you when there's a risk of underperformance. That means smoother, more productive business calls… and fewer colleagues complaining to you about the VoIP system.
Goodbye, freeze frame: Why choose PRTG as your MOS monitoring tool
Enhance VoIP service
Not just your MOS. Detect and analyze all kinds of call quality issues such as audio codecs, jitter values, latency, duplicate packets, or even packet loss. With PRTG, you no longer have to search for the needle in the haystack – you’ll immediately see what’s the root cause of an issue.
Enjoy end-to-end visibility
Not just the quality of service. PRTG monitors your whole network: applications, bandwidth, hardware, traffic, virtual machines… you get the idea. See all your critical stats at a glance, in real time, optimize performance, and stop wasting hours (or days) troubleshooting issues.
Receive real-time alerts
Pick your preferred performance thresholds, and PRTG will email you, text you, or send an in-app notification when you're at risk of going under or over, so you can fix them promptly and avoid disruption. It's really as simple as that.
Suffer from less stress
Because, let's face it. At the end of the day, you want to do your job well and go home at a reasonable hour. PRTG works continuously in the background, keeping an eye on things so you don't have to, and helping you ensure your network stays fast and stable for best end-user experience
What MOS monitoring looks like in PRTG
Diagnose network issues by continuously tracking audio codecs, quality of service parameters, network congestion, and other Voice over IP attributes. Show mean opinion scores and other key audio and video metrics in real time. Visualize data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot and fix the causes of poor voice quality in calls and other VoIP issues.
Start MOS monitoring with PRTG and see how it can make your network more reliable and your job easier.
What's your MOS? How mean opinion score monitoring with PRTG works
PRTG monitors MOS using sophisticated preconfigured sensors that track key audio and video attributes round the clock. Set a warning or error threshold of your choice, and PRTG will let you know as soon as that variable risks going under or over it, so you can step in and fix the issue.
QoS (Quality of Service) One Way
The QoS (Quality of Service) One Way sensor monitors parameters regarding the quality of a network connection between two probes. It sends a series of UDP packets from the source probe to a target probe and can show the following parameters:
- Minimum, maximum, and average jitter
- Minimum, maximum, and average packet delay variation
- The number of corrupted, duplicated, and lost packets
- The time to last packet
QoS (Quality of Service) Round Trip
The QoS (Quality of Service) Round Trip sensor monitors parameters regarding the quality of a network connection between two probes. It sends a series of UDP packets from the source probe to a target probe at the end of the connection line. Then, the target probe sends the packets back to the source probe. It can show the following parameters:
- Minimum, maximum, and average jitter
- Minimum, maximum, and average packet delay variation
- Minimum, maximum, and average RTT
- The number of corrupted, duplicated, and lost packets
- The MOS
SIP Options Ping
The SIP Options Ping sensor monitors the connectivity to a Session Initiation Protocol (SIP) server using SIP options "ping". It can show the following parameters:
- The response code
- The response time
Cisco IP SLA
The Cisco IP SLA sensor monitors VoIP network parameters using IP service level agreements from Cisco. It can show the following parameters:
- The average jitter between source and destination and vice versa
- The minimum, maximum, and average latency between source and destination and vice versa
- The minimum, maximum, and average RTT
- The ICPIF
- The number of late, lost, and out-of-sequence packets
- The MOS
SNMP Cisco CBQoS
The SNMP Cisco CBQoS sensor monitors network parameters using Cisco's Class Based Quality of Service (CBQoS). It can show the following parameters:
- The current and maximum queue depth
- The number of drop and pre-policy packets
- The drop, post policy, and pre-policy size

Monitoring the mean opinion score: FAQ
What is MOS?
MOS – the mean opinion score – rates the voice and image quality of a VoIP transmission. It is the arithmetical average of several parameters. The lowest MOS is 1, while the highest MOS is 5.
How do you calculate MOS?
MOS is an average of the performance of various video and audio attributes. ITU-T – the United Nations' International Telecommunication Union Telecommunication Standardization Sector – has established standard tests for evaluating the quality of both video and audio.
What is a typical mean opinion score?
A VoIP MOS score of 1 means that despite great effort, it is impossible to understand what is being said during the call (the call repeatedly cuts in and out). A score of 5 means the quality is excellent, with no effort required to understand what is being said. MOS tests make it possible to compare a variety of codecs and audio connections.
What is a codec?
“Codec” is short for “coder-decoder.” With a codec, data or a signal is digitally coded then decoded. This process is not immune to dips in quality. In telephone networks, a large number of codecs is used, each of which has its own MOS. The MOS makes it easy to compare the quality of the various codecs.
Why use a MOS monitoring tools like PRTG?
MOS monitoring tools like PRTG enable you to assess how your organization's VoIP system is doing at a glance. Check the dashboard, and you'll get your current MOS score straight away. Better still, PRTG alerts you as soon as there's a risk of issues, so you can fix them before your MOS goes down.
What is a sensor in PRTG?
In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.
On average, you need about 5-10 sensors per device or one sensor per switch port.
