Visualware MySpeed (online-service)
It is likely one of the simplest and available tests. On the website http://myspeed.visualware.com it is necessary to select the region, the next server (for Russia the closest in Germany) and to click start. In several seconds it is possible to enjoy information on link quality in an available graphic type.
Information on jitter, losses of packets on the channel, and also MOS is available.
Just it is clear and conveniently, the main thing hundred it are available to NE to the technical person.
The developer — the TamoSoft company. I would call it commercial Wireshark, applications are quite similar externally and by the principle of information display, however, CommView have some "spetsializirovannost" for VoIP.
The main tab displays all active sessions, at the same time even shows belonging of the IP address to any country. For example, it is visible that the SIPNET (126.96.36.199) server is noted by a flag of the Czech Republic :)
The VoIP-Potoki RTP tab will show the complete information about connections, plus to it the analysis of quality of a voice (MOS and R-factor parameters).
The tab of VoIP-station shows all active connections, by the way, it became clear that at our test server the friend scanner (friendly-scanner) was brought, but it is most likely an online service for a link quality assessment.
The VoIP-Registratsii tab, shows successful and unsuccessful requests for authorization.
The application is commercial, costs 36 000 rub, but there is a trial version for 30 days. Huge plus is visualization and simplicity of mastering, after Wireshark it is simple "an eye has a rest". Support of Russian and fitness under VoIP pleased.
Wireshark probably the most popular product in respect of the analysis of a traffic and this popularity most likely is caused by free of charge. As a rule in VoIP this product is used for the analysis of signaling, but today we will consider functionality from the point of view of the analysis of quality of a voice.
Everything that to us interestingly is in the section Telephony. The section Telephony-SIP, it is possible to trace in real time challenges here and …
to look at process of call setup in a graphics mode.
The section Telephony-RTP, displays voice flows, from useful statistics are present jitter and losses of packets.
Pluses — the free application, minuses — is not present convenient graphic representations and saving of statistics.
VoIP Spear (online service)
http://www.voipspear.com conditional free service for quality control of the channel from the point of view of VoIP.
In the free mode can monitor a traffic in the last 6 hours, Only one point. Measures MOS, a delay and losses of packets. There is an expanded functionality for money including sending notifications.
VoIP Monitor (online service)
http://www.voipmonitor.org rather abrupt piece which most likely is more calculated on telecom operators. It is put on the server and collects a heap of parameters.
Trial for 30 days free, further from 42 USD a month for 10 channels. It is possible to subscribe for a cloud service — 20 USD a month for 3 channels.
It is a lot of monitoring parameter with notifications, necessary to us MOS and loss of packets are there.
Total, if business is strongly started on communications by phone (I think that for the companies with loading from 30 simultaneous challenges), such piece needs to be had. A heap of settings, the sea of notifications, pleased built in antifraud. Minus — in order that it is necessary to configure all this well to understand the subject VoIP.
StarTrinity SIP Tester (application)
The application is positioned first of all as the generator of calls, but too is suitable for our purposes. The free version assumes 150 attempts of calls from the application and 50 simultaneous challenges in respect of loading.
To start test challenges it is necessary to register at least one number on automatic telephone exchange. Then it is possible to start Outgoing Call Simulation (the upper menu)
The application to phone to the specified number, a little with it is necessary (with the application) to talk then will issue detailed statistics on a call (MOS is there).
By the way, 3CX is in the list of the supported IP automatic telephone exchanges.
It is possible to download 3CX Phone for Windows on the website 3CX.RU
Pay attention that 3CX Phone works only with the automatic telephone exchange 3CX Phone System for Windows.
