Caller quality of experience measurement. Do you know about issues bothering your callers that you might not know?
How to quickly setup SIP / VoIP call quality testing?
Using QualTest it’s easy:
🔘 Quick way to measure quality of SIP / VoIP call without installing complex software solutions
🔘 Runs on Linux (including ARM builds)/ macOS/ Windows operating systems:
🔘 Quality measurement is based on Sevana waveform analysis technology and network statistics such as packet loss, jitter etc (E-Model)

Sevana PVQA – Passive Voice Quality Analyzer is the tool that will help you with this task.
It is a unique powerful tool to non-intrusively (without comparing with reference audio file) evaluate voice quality by waveform analysis. PVQA MOS is perhaps the most accurate compared to other tools that predict MOS score by single file waveform analysis. Tool performance and ability to work in real-time give companies an opportunity to develop their own voice quality testing solutions not being dependent on particular hardware and software. PVQA is available as a cross platform application or library for all main desktop and mobile operating systems. Keep an eye on call quality with sevana.biz
How well do you know your network?
Do you know that in a packet switched network you may not only rely on ITU-T G.107 E-Model MOS and R-Factor? There are lots of other issues that affect QoE of your subscribers besides typical metrics such as jitter, latency, packet loss, or RTT delay.
Learning about issues “inside” the call gives you a unique chance to detect the issues not necessarily connected with network KPIs.
Ask us how knowing about Silence, Audio gaps, Clipping, Echo and Noise will help you to increase callers satisfaction and prevent their complains.
AQuA perfectly suits IVR systems testing when one has a reference audio (original quality IVR prompt) to compare with the recorded audio. But how to validate IVR prompt quality if there is no reference to compare with? However, there is a possibility to validate IVR prompt quality even without comparison by using Sevana PVQA. It is just the same way as one analyzes voice quality of call recordings, because PVQA can forecast a quality score by waveform analysis of a single audio file. Contact us to learn more!
