VoIP Jitter
Monitor and reduce VoIP Jitter with PRTG
VoIP jitter is one of the most frequent problems in voice over IP telephony. High levels of VoIP jitter can result in bad call quality or long delays in the conversation.
PRTG Network Monitor includes comprehensive QoS monitoring functionality. With its built-in QoS (Quality of Service) sensor, PRTG is the perfect tool for VoIP network monitoring. It measures the quality of a network connection by looking at "quality of service" parameters such as jitter, packet loss, duplicate packets, packet delay and other readings.
How Can I Use PRTG to Reduce Jitter Noise?
As PRTG measures VoIP jitter in ms according to RFC 3550, you can create alarms that will be triggered if the jitter delay is longer than the amount of time you consider to be acceptable jitter (The International Telecommunications Union recommends VoIP jitter of less than 150 ms one way). So if the latency jitter is more than this amount of time, you will be notified and can then take steps to reduce VoIP jitter (prioritize VoIP traffic over the network, reserve more bandwidth for phone conversations, optimize packet size and jitter buffering etc.).
Free VoIP Jitter Monitoring
PRTG Network Monitoring Software is available in two editions. For basic, free VoIP jitter monitoring, the Freeware Edition may be downloaded and used for personal and commercial use completely free of charge. For more advanced needs, licenses for the Commercial Editions start at $400 / €300.
Apart from being an excellent VoIP monitoring manager, PRTG Network Monitor is also a very powerful bandwidth, availability and internet monitoring software. There is even an iPhone application for PRTG: iPRTG is the mobile network monitoring solution which allows administrators to check their network’s performance from wherever they are.
