In Search of Quality of Service Testing, Part I

September 5th, 2006 by Martin Cadirola

Most of us working in the VoIP industry understand the importance of Quality of Service (QoS) when making voice and video calls. And obviously the end-user is the one that will adopt more VoIP services as he or she perceives that there’s not much difference between a regular Telco and a VoIP provider.

There are many factors involved in QoS, many of which we will summarize in future posts in this blog. In the mean time, I recommend you check out Brix Networks’ TestYourVoIP site. It has a cool web-based Java applet that measures voice MOS Score in real-time by simulating a phone call to different destinations. You can also test IP Video using their sister site, TestYourIPVideo. The most interesting application is the “Internet Phone Quality Google Gadget”, basically a little piece of software that lets you make all these measurements right from the desktop using Google Desktop. All of these tools are available for free.

Regardless of the what’s going on these days the fact is that 5 years from now, QoS (and hopefully prices) will be a lot better than today. Have you come across other VoIP tools? Please let us know!
