VoIP Problems: How to Deal with Packet Delays

Published: Sep 17 Filed Under: noise

VoIP sometimes gets a bad rep because of data packet delays, which lessen audio and video quality. The effect of packet delays to VoIP quality varies – and there will always be packet delays.

Delays are natural occurrences in telecommunications, even traditional communications. After all, voice and data travel through a series of systems: from satellites to landlines, or from servers to landlines to your digital phone. The difference between one service and another is the amount of delay. And delay has a direct effect on the quality of communications.

VoIP Spear Refresh

Published: Jan 29 Filed Under: news

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.

New codecs!

Published: May 17 Filed Under:

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.
