VoIP Monitoring: Why and How PRTG is Different for QoS and IP SLA Monitoring

Appreciating the benefits of mobile communication, we all have learned to condone some lack of speech quality when using our mobile phones. The possibility to communicate with everyone everywhere often brings a much greater value than an overwhelming speech quality. But when it comes to Voice-over-IP technology, you can have both: Using one of the latest high density (HD) audio codecs, the connection quality can be astonishing (far better than in usual landline communication) and you can even use it wireless on the go with the according mobile provider and device.

So much for theory! In practical experience, VoIP communication isn't so easy. Users often experience connection failures, speech delays or a "robot-sounding" voice, echoes and lost speech fragments in Voice-over-IP telephony – even in wired networks. Often, persistently annoying speech quality is the consequence. The reason for this, generally spoken, is a bad Quality-of-Service (QoS) in the network, either on the sender's and/or on the receiver's side or somewhere in between. Among other failures and delays in your network, bad QoS can make VoIP communication virtually impossible. With PRTG Network Monitor, you are able to find the bottlenecks – even using the Freeware Edition!
