- QoS Monitoring & IP SLA Monitoring. All in one.
- PRTG monitors the VoIP quality and runs VoIP latency tests.
- PRTG alerts you before phone errors occur.
VOIP MONITOR: WITH PRTG, EVERYTHING IS INCLUDED
FREE QOS MONITORING
PRTG's predefined QoS Round Trip Sensor measures the Quality of Service of your lines. Some of the parameters covered by this sensor are latency, jitter, packet loss, duplicate packets, and the Mean Opinion Score (MoS). This sensor is included free of charge! There are no hidden costs. On the contrary - take advantage of this sensor along with the other 100 free sensors for as long as you use PRTG.
FREE IP SLA MONITORING
Higher-priced Cisco switches and routers have a built-in monitoring tool, or so-called IP SLA monitoring. Among other things, IP SLA monitoring measures the quality of your service. PRTG provides a preconfigured Cisco IP SLA Sensor for this purpose. With this sensor, PRTG lets you monitor your Cisco device data - at no extra charge - as part of the 100 free sensors that you can use to get started. You may also choose to use it as part of your license, and thereby simplify the calculation of your purchase cost.
CUSTOMIZABLE NOTIFICATION SYSTEM
PRTG's alarm feature runs discreetly in the background and focuses on that which is most important. Notifications are customizable according to your needs. Decide when alerts should be sent, and the way you would like to receive them: by email, SMS, or page. As an IT manager, you can rest assured that you will be notified of issues promptly, before emergencies crop up. This alarm feature is likewise included!
Thanks to the dashboard designer, you can create your own personal dashboard - and keep a constant eye on your entire monitoring environment. For inspiration, see some examples of dashboards from our users. Even while on the go, you'll enjoy a constant overview by way of our app, which is available for Android, iOS, and Windows phones.
COMPREHENSIVE NETWORK MONITORING
PRTG is more than "just" a VoIP monitoring tool. It also lets you monitor, among other things, your bandwidth, LAN, servers, and CPU. PRTG is an all-in-one solution. Once it is configured, your monitoring is good to go, and you can confidently go about your work. It is easy to see why so many of our customers love our tool!
VIEWS OF VOIP MONITORING WITH PRTG
A QUICK OVERVIEW OF PRTG: VOIP MONITORING
DEFINITIONS: VOIP, QOS MONITORING, IP SLA CONFIGURATION
Voice over Internet Protocol (VoIP)
VoIP has become the telephony standard in medium-sized companies and groups. Every VoIP call saves money. VoIP software is easier to configure and more versatile. The voice is digitized, then sent across the network connection and reassembled. This process, however, is prone to malfunctions. Some examples: packets arrive too late, as duplicates, or in the wrong order...
With QoS monitoring, data line performance is monitored using parameters such as latency, packet loss, and jitter. QoS monitoring can take place internally, i.e. as inside a large building (the company LAN). Otherwise, the connection to external offices in other locations can be monitored if the latter are equipped with remote probes suitable for VoIP monitoring. More information on Quality of Service monitoring.
IP SLA CONFIGURATION
For IP SLA monitoring, first you must properly configure your Cisco devices, and then add them to PRTG. Be sure to enable SNMP access, for data will be queried via this protocol. In the second step, create the appropriate IP SLA sensor and follow the subsequent instructions. The first data will arrive in no time at all. More information on IP SLA.
YOUR VOIP MONITOR – EVEN ON THE GO
PRTG can be installed within minutes and it's compatible with most mobile devices.
“The support we received from Paessler AG was extremely reassuring. Their reaction time, know-how, and solutions were outstanding in every department.”
Andreas Reimann, Senior Networking Communication Architect at Zürich Airport. Zürich Airport uses more than 4,500 sensors for its monitoring. To the case study (german)
PRTG simplifies your day
Our monitoring software works for you and promptly notifies you of potential issues.
It frees you to concentrate on your day-to-day tasks with peace of mind.
PRTG SAVES TIME
PRTG is quick to report complications - before the onset of crashes. For you, this results in less work and greater savings. And by keeping a constant eye on latency, packet loss, and other parameters, you'll also optimize the quality of your VoIP calls.
PRTG SAVES WORRY
Setting up PRTG takes no time at all. 200+ predefined sensors provide for comprehensive network monitoring. PRTG comes equipped with several VoIP sensors, including those designed for Cisco devices. Initial monitoring is set up automatically during installation.
PRTG SAVES MONEY
80% of our customers report substantial or even exceptional network management cost savings. Our customers report that their PRTG licenses have paid for themselves in an average of 3 ½ months.
PRTG – Smart Setup
by Kimberley, Product Evangelist
Here we show you the first steps with PRTG: from the installation to the initial configurations, we explain how easy PRTG works and how the software is built.
Frustrated with your current monitoring software? A tip for those making the switch
Do you currently use Nagios or other commercial monitoring software? Frustrated with awkward user interfaces and hidden costs? Then make the quick and easy switch to PRTG. Our Smart Setup is extremely user-friendly. Installation takes a few short minutes. Preconfigured sensors are automatically created during setup - another free PRTG feature.
MEASURING QUALITY OF SERVICE (QOS) WITH PRTG
When calling, perhaps the following are true: There is static on the line. There are delays. There are echoes.
If so, then you have a problem with the quality of your VoIP service. Take advantage of the parameters below to measure performance.
Latency: Latency measures the time data packets need to travel from the sender to the recipient. According to ITU-T, which is responsible for telecommunications standards within the International Telecommunications Union, delays should not exceed 125 milliseconds. When it comes to latency, PRTG recommends a maximum delay of 100 milliseconds, in order that you may be notified sufficiently in advance and can react before noticeable disruptions occur.
Packet losses: Packet loss is one of the most frequent errors to take place during VoIP, as well as during video conferences and streaming. ITU-T recommends a maximum loss rate of 5 percent. For packet losses, PRTG recommends a default setting of 0%. For even the smallest losses can cause interruptions. PRTG also lets you know if packets are "duplicates" or "out of order."
Jitter: Jitter is also an important parameter for determining your quality of service. Jitter measures the deviation from the average latency value. PRTG recommends that this deviation be less than 20 to 25 milliseconds. This value, too, lies significantly below the ITU-T recommendation.
Mean Opinion Score (MOS): The MOS rates the call quality on a scale of 1 to 5. The higher the score, the better the quality. The rating is based on jitter, latency, and other parameters. MOS is a kind of summary that is displayed in the sensor overview with the other key information.
The Swiss Army knife for admins
Adapt PRTG individually and dynamically, to your specific needs, using the API:
- HTTP API: Access monitoring data and manipulate monitoring objects using HTTP requests
- Custom Sensors: Create your own sensors for customized monitoring
- Custom Notifications: Create your own notifications to send alarms to external systems
150,000 administrators worldwide trust in our software.
Praxis-Tipp: "Practical tip: “Hey Stephan, do you have any tips for VoIP monitoring? ”"
“To simulate a telephone that uses the same network as your real IP telephone, simply set up our QoS Reflector Script on a Raspberry Pi and connect the latter to the desired point on the network. By doing so, you can guarantee that you are measuring the right network path with our QoS Round Trip Sensor. This is important because VoIP traffic is usually treated with priority.”
Stephan Linke works in the PAESSLER AG Technical Support department.
