Network Physics VoIP Quality Monitors
VoIP sys admins will have another potential tool in their arsenal with new VoIP quality monitors
from Network Physics.
The offering, called NetSensory Solution Insight for VoIP, works as an
extension set for Network Physics' appliances. These extensions measure
over 60 metrics related to VoIP call quality.
As I've pointed out before, there are many factors that affect VoIP call service, but I wouldn't have thought there were even 60 IP metrics, let alone that many that affect call quality. Things I haven't touched on before, which Network Physic's solution does, includes using the appropriate CODEC (Coder-decoder) algorithm. Essentially, there are different algorithms to compress and decompress digital audio data, and some perform on the fly better than others, depending on issues related to both network and computing resources.
