The purpose of this quick how-to document is to show that implementation of a voice quality monitoring system may be relatively simple. The most complicated task is to find an easy to use and cost effective solution that would provide a perceptual evaluation of voice/speech quality recorded by your SIP-system. However, Sevana NIQA was an easy choice. We decided to use one of the most popular free SIP softphones ? pjsip (www.pjsip.org). This is a cute, light, but powerful tool that can do the two main things required for creating a VQM system: a.. functionality to make SIP calls ? obviously all SIP phones have this functionality b.. ability to play and record audio files If you have a SIP software phone that supports these two features (and most likely any of them does) then by using Sevana?s AQuA or NIQA product you can setup a simple Voice Quality Monitoring (VQM) within a couple of minutes.
