VoIP systems have a reputation as some of the most high-maintenance systems in networking. VoIP phone systems have minimal tolerance for poor performance as just a little latency and packet loss can have a devastating impact on audio quality. Using VoIP monitoring tools is the only way to make sure that your network can support VoIP systems.
With VoIP monitoring tools you can measure connection quality within your network to make sure that your phone calls aren’t experiencing choppy audio. Crucially a VoIP monitoring tool will allow you to see how much latency and packet loss is present on your network. In this article, we’re going to look at the best VoIP monitoring tools and software for 2020.

The best VoIP Monitors
First up on this list we have SolarWinds VoIP and Network Quality Manager. SolarWinds VoIP and Network Quality Manager allows you to monitor VoIP call performance and WAN performance. VoIP metrics that you can track include jitter, latency, Mean Opinion Score (MOS), and packet loss. These metrics tell you if VoIP calls are being delivered with poor quality.
In the event that you need to run extensive troubleshooting you can go through your call records to find information that can show you what is causing poor performance. You can search for calls by call origination, call destination, call manager, call time, call status, and call quality. This helps to move the troubleshooting process along quickly.
SolarWinds VoIP and Network Quality Manager is accessible to organizations because it offers a simple user interface and it can be deployed in less than an hour. Deployment is fast-tracked because the platform automatically discovers Cisco IP SLA-enabled devices. Autodiscovery means that the user doesn’t have to configure everything manually.
Overall SolarWinds VoIP and Network Quality Manager is a choice that is suitable for organizations of all sizes looking for a VoIP monitoring tool. SolarWinds VoIP and Network Quality Manager starts at a price of $1,602 (£1,225).
Call Detail Record Tracker is a free VoIP monitor available for SolarWinds. This is a good option if you want the competence and reliability of SolarWinds software, but don’t want to pay in order to use the company’s top-of-the-line VoIP Network and Quality Manager.
The Call Detail Record Tracker fulfills the functions spelled out in its name. It enables you to search through VoIP-related status records that have been gathered on the network. Those records need to be supplied by the Cisco CallManager system. CallManager is also known as Cisco Unified Communications Manager.
The data searcher can store and aggregate call detail records (CDRs) for up to 48 hours, so you can perform some analysis functions within the tool or export data through to some other network analysis utility.
You can derive statistics for jitter, latency, packet loss, and MOS (mean opinion score) through this tool.
The great thing about the Call Detail Record Tracker is that it is free. However, its functionality is not even close to the facilities of the SolarWinds Network and Quality Manager.
This tool would work well as an informative sidekick to more comprehensive network performance monitoring software. In those instances, it can help a network administrator zoom in on VoIP traffic if some issues arrive with elements of your network infrastructure. The SolarWinds Call Detail Record Tracker installs on Windows Server and is available for download as a free tool.
PRTG Network Monitor is a network monitoring tool that offers a VoIP monitoring experience with free QOS and IP SLA monitoring. QoS monitoring with PRTG Network Monitor takes place with the PRTG Round Trip Sensor which measures latency, jitter, packet loss, duplicate packets, and Mean Opinion Score. Likewise there is a Cisco IP SLA Sensor for monitoring Cisco device data.
The wider monitoring experience is completely personalizable according to your requirements. The dashboard can be personalized to include widgets and metrics of your choosing. You have complete control over the data that you see on the dashboard. For VoIP monitoring we recommend that you use the PRTG Round Trip Sensor to give you a snapshot of your VoIP call performance when you log in.
The performance of your VoIP calls doesn’t need to be tracked manually all the time either. Instead, you can use the notifications system to keep you updated when VoIP calls experience poor quality. PRTG Network Monitor sends notifications by email, SMS, and push notifications. These are great because they ensure that you know the moment VoIP calls decline in quality.
PRTG Network Monitor is available as a free and a paid tool. You can use the PRTG Round Trip Sensor and the Cisco IP SLA Sensor completely free of charge. However, if you want to monitor a network with more sensors then you can purchase anywhere from 500 sensors for $1,384 (£1,057) and $13,226 (£10,104) for unlimited sensors. You can download the free trial.
ThousandEyes is a network monitoring platform that doubles up as one of the best VoIP monitoring tools on the market. ThousandEyes correlates VoIP performance with the core performance metrics like latency, packet loss, and jitter. These are the basic indicators for seeing how well VoIP services are functioning.
One of the things that makes ThousandEyes special is that you can simulate VoIP calls between agents and offices. This allows you to put your VoIP service to the test. There is also a voice test feature, which allows you to test for SIP connectivity before you initiate a TRP call.
The ThousandEyes platform has been designed with troubleshooting firmly in mind. For instance, you can track infrastructure faults down to link and interface with SIP and RTP network paths.

Through the dashboard, you can see how many calls are successful or failing.
There are a range of metrics that you can monitor with ExtraHop. By installing the SIP VoIP Call Dashboard you can monitor call session status, call volume, load balancing, routing call quality, and Non-VoIP protocols. With regards to metrics you can monitor, you can view active calls, call attempts, call failures, 5xx error codes, short calls, call length, and call failures.
ExtraHop is also one of the most convenient VoIP monitoring tools because it allows the user to automatically discover devices within the network. The advantage of this is that you can sidestep the inconvenience of configuring your entire network from scratch.
Dotcom-monitor Server Monitoring offers premium VoIP Monitoring and SIP protocol monitoring. The core focus of this product is monitoring the availability of VoIP infrastructure. In the ServerView display, you can view outgoing call success, inbound call routing, internal extension connectivity, and voicemail availability.
Similar to all the best VoIP monitoring tools, dotcom-monitor Server Monitoring has a complete alerts system. Alerts keep you notified when VoIP calls are not performing when they should. Users receive notifications when error messages are received from the server and the expected call result isn’t received.
Once you’ve established VoIP calls are performing poorly dotcom-monitor Server Monitoring helps you point to the root cause. SIP Monitoring error detection records properties of the error so that you can address the root cause. You can also generate SIP monitoring reports to evaluate performance from a distance.
