Sevana helps telecom solution providers build voice quality straight into their own products. You can embed our scoring engines as cross-platform libraries, automate capture analysis in your pipelines, or deploy a ready monitoring server, so you ship a quality story your customers can see. Below are the building blocks: the AQuA and PVQA libraries, the PCAP Analyser and Pcaptix for capture analysis, and VQ Monitor for live traffic.
AQuA library
AQuA is a cross-platform library for intrusive, reference-based perceptual voice quality scoring, trusted by integrators since 2009.
Embed it anywhere
Because AQuA ships as a cross-platform library, you can integrate perceptual scoring directly into your own application on the operating systems you already support.
Language-independent
Moreover, the analysis does not depend on the spoken language, so a single integration scores calls in any language your customers carry.
Tune to your environment
In addition, you can build a parameters profile that suits your operating environment, which keeps MOS scoring aligned with the conditions you test in.
PVQA library
PVQA is a non-intrusive RTP library that scores voice quality from waveform analysis alone, mapping network metrics to the audio impairments behind them.
Real-time network stats
Because it works on live RTP, PVQA reports network MOS and a range of waveform KPIs as the call happens, not after the fact.
Root-cause discovery
Moreover, impairment analysis speeds up root-cause identification and surfaces packet-loss patterns inside the call audio itself.
Runs on your stack
In addition, you can integrate the library into an existing system or build a new one, on whatever hardware and operating system you run.
PCAP Analyser
The PCAP Analyser is a scriptable command-line tool that estimates voice quality from a PCAP file, built for batch pipelines and big-data work.
Parse every stream
Because it reads the capture end to end, the tool finds network MOS and Sevana MOS for all streams and matches network metrics with waveform analysis.
Pattern discovery
Moreover, it generates call-quality big data, so you can discover impairment patterns across large volumes of traffic.
Any network
In addition, it scores calls on any type of network, with a wide range of codecs supported out of the box.
Pcaptix
Pcaptix is the interactive desktop and web app for VoLTE and VoIP analysis from captures, giving telecom solution providers a ready tool to ship or use in house.
Dual MOS per stream
Because each stream earns a Sevana perceptual MOS beside a network-estimated MOS, an engineer can tell a transport fault from an audio fault at a glance.
SIP call flow
Moreover, the call-flow ladder and full SIP message list make a failed registration, a codec mismatch or an authentication loop easy to spot.
Cross-stream statistics
In addition, an aggregate pass ranks which network conditions hurt quality, with optional per-subnet grouping for route-level insight.
VQ Monitor
VQ Monitor is a real-time call quality monitoring server that analyses VoIP or mobile traffic carried as RTP, so your team sees issues as they happen.
Real-time alerting
Because it watches live traffic, VQ Monitor notifies your team about quality issues in real time, so support can act while a call is still in progress.
Impairment detection
Moreover, one tool detects silent and noisy calls, dead air, amplitude clipping and echo across the traffic you monitor.
Network and audio together
In addition, it watches network and audio quality at the same time, so the two views always line up for the same call.
