VoIP Spear has been operating since 2008 and the site was starting to lose it's sheen, so we decided to do a refresh. At first, we were planning minor changes only, but one thing led to another and, before we knew it, two months of intense programming had passed.
The biggest change is the main chart page. We replaced the old Flash charts with Google charts. More significantly, we're now showing just one time period on the page. The default view is a six hour time period, and it's easy to change that. Also significant, we've broken the three main data points (MOS, packet loss, latency) out into their own charts.More
On January 20, 2013, between 11:00pm and 1:00am EST, we will be performing maintenance on the VoIP Spear web server. As a result, the web site may be unavailable for a period of up to one hour.
Testing results will be unaffected by this maintenance.More
VoIP Spear has always included the ability to calculate MOS using the big three codecs of VoIP: G.711, G.723, and G.729. We've recently added support for GSM, G.722, Speex, and iLBC.
VoIP Spear uses the E-Model of computation for estimating MOS from network statistics like packet loss, latency, and jitter. In order to complete the E-model calculations, we need to know some characteristics about each codec. For example, how much does the codec itself degrade voice quality. Another characteristic would be: how does the codec perform under packet loss conditions.More
It's not news that VoIP is becoming more and more mainstream all the time, but it sometimes amazes me how far it's come. I first started up a VoIP company about 9 years ago and VoIP was so far out on the fringes that we would never use that term when speaking to customers.
Today, I came across a blog posting about potential uses for VoIP in a physician's medical practice. Seven Great Applications for IP-PBXs in the Medical Practice is a quick read and worth a few minutes of your time. For me, the most interesting takeaway from the article is that it confirms how far into the mainstream VoIP is when there's articles discussing its uses for such a narrow vertical.More
A while back, I noticed a nice little feature about VoIP Spear at VoIP Resources. It's flattering to see a positive review like this.
We're especially pleased that the author of the article really seems to get VoIP Spear. She starts off by describing VoIP QoS problems at a high level. When VoIP Spear is introduced as a tool, the article mentions that one advantage is that it is "no-client side". This is a subtle point that is easy to overlook -- there's no software to install. You can just enter your IP address into the VoIP Spear web site and it will start its monitoring.More
