Recently a couple of posts discussing VoIP Quality:

Om Malik reports on a Brix Networks study, based on data collected on Acceptable Call Quality via their TestYourVoIP.com site.  Note that Brix also announces the availability of this service as a Google Gadget (for Google Desktop) providing ongoing measurement of the quality of your connection for voice and video activities. The study reports an ongoing decline in VoIP Acceptable Call Quality from 84% to about 80% over the period December 2004 to May 2006.

Andy at VoIP Watch found  MyVoIPSpeed Internet Connection Test and was using it as a tool to measure the connection speeds and QoS at the hotel he was staying at. I checked out my own home office connection and got this report:

Om talks in his post about degrading quality of calls received from callers using Vonage. I have been a Packet8 subscriber for almost three years and have found the quality to consistently improve over time to the point where I have minimal problems. I also find I am getting a high quality level with my Skype and SkypeOut calling with one exception: SkypeOut calls to some wireless phone services.  Too much compression/decomprssion going on? first via VoIP, then at the wireless end?

I also ran the Brix TestYourVoIP and got a MOS score of 4.2, close to the MyVoIPSpeed result shown above of 4.0. The tests appear to have some level of consistency across the tests and do appear to reflect the quality of calls that I am experiencing.
