VoIP quality degradation shows need for prioritization

A study by Brix Networks, which runs TestYourVoip.com, shows that the quality of VoIP calls has degraded over the last 18 months. Their tests of VoIP connections show that 20 percent of calls have unacceptable quality, up from 15% 18 months ago. Brix's CTO says that the cause is competition for network resources--i.e., congestion.

The solution is, of course, prioritization--putting voice and other latency and jitter-sensitive traffic in a higher class of service with QoS (quality of service).
