We test the quality of VoIP passing through common channels (Windows)
Previously, we thoroughly dismantled utilities for Android and iOS to test the quality of the channel from the device to the IP-PBX. Only Windows remained.

For those who are not familiar with 3CX Phone for Windows, a small video.

This is probably one of the easiest and most accessible tests. On the site http://myspeed.visualware.com you need to select your region, the nearest server (for Russia is the closest in Germany) and click the start button. After a few seconds, you can enjoy channel quality information in an accessible graphical form.
Information is available on jitter, packet loss on the channel, and MOS.
Simple, understandable and convenient, the main thing is that this is NOT a technical person.
Developer - TamoSoft company. I would call it commercial Wireshark, applications are quite similar in appearance and on the principle of displaying information, however, CommView has some “specialization” just for VoIP.
The main tab displays all active sessions, even showing that the IP address belongs to a particular country. For example, it is clear that the SIPNET server (212.53.40.40) is marked with the flag of the Czech Republic :)
The VoIP RTP Streams tab will show complete connection information, plus a voice quality analysis (MOS and R-factor parameters).
The VoIP Station tab shows all active connections, by the way, it turned out that our test server had a friend scanner (friendly scanner), but this is most likely an online service for assessing channel quality.
The VoIP Registration tab shows successful and unsuccessful authorization requests.
The application is commercial, it costs 36,000 rubles, but there is a trial version for 30 days. A great advantage is the visibility and ease of development, after Wireshark just "the eye is resting." I was pleased with the support of the Russian language and precisely the fitness for VoIP.
Wireshark is probably the most popular product in terms of traffic analysis, and this popularity is most likely due to the free of charge. As a rule, in VoIP this product is used for signaling analysis, but today we will consider the functionality from the point of view of voice quality analysis.
All that we are interested in is in the Telephony section. Section Telephony-SIP, here you can track calls in real time and ...
see the process of establishing a call in graphical mode.
Section Telephony-RTP, displays voice streams, from useful statistics there are jitter and packet loss.
Pros - the application is free, cons - there is no convenient graphical representations and saving statistics.
http://www.voipspear.com conditionally free service to control the quality of the channel in terms of VoIP.
In free mode, it can monitor traffic for the last 6 hours, Only one point. Measures MOS, delay and packet loss. There is an advanced functionality for money, including sending notifications.
http://www.voipmonitor.org is a pretty cool thing that is most likely designed for telecom operators. It is put on its server and collects a bunch of parameters.
The trial for 30 days is free, further from 42 USD per month for 10 channels. You can subscribe to the cloud service - 20 USD per month for 3 channels.
There is a lot of monitoring parameter with notifications, we need MOS and packet loss there.
So, if a business is strongly tied to telephone communications (I think that for companies with a load of 30 simultaneous calls), you just need to have such a thing. A lot of settings, a lot of notifications, pleased with the built-in antifraud. Minus - in order to configure all this you need to be well versed in the topic of VoIP.
The application is positioned primarily as a generator of calls, but it is also suitable for our purposes. The free version includes 150 call attempts from the application and 50 simultaneous calls in terms of workload.
In order to run a test call, you must register at least one number on the PBX. Then you can run Outgoing Call Simulation (top menu)
The application will dial the specified number, you need to talk a little with it (with the application), after which you will receive detailed statistics on the call (MOS is there).
By the way, 3CX is in the list of supported IP PBXs.
