Sevana gives mobile operators a practical way to keep voice quality high across the network. You can analyse recorded captures offline, watch live traffic as it flows, and place test calls on real handsets in the field, so you can catch and resolve quality issues early, whether you are investigating a past incident, monitoring continuously or validating proactively. Three products cover that ground: Pcaptix for offline VoLTE call quality analysis from packet captures, VQ Monitor for real-time analysis of calls already in your network, and QualTest for active mobile-to-mobile testing.

Pcaptix for VoLTE analysis from captures

Pcaptix turns a packet capture into VoLTE call quality analysis, so mobile operators can investigate a recorded .pcap from the IMS core without standing up live infrastructure.

Pcaptix unified view: a SIP call overview with per-stream quality warnings.

VoLTE codecs from the capture

Because it extracts the SIP and IMS signalling and reconstructs the RTP media, Pcaptix decodes the VoLTE codecs AMR-NB, AMR-WB and EVS, so perceptual scoring works on the audio your subscribers actually heard.

Dual MOS per stream

Moreover, each stream earns a Sevana perceptual MOS beside a network-estimated MOS, which helps separate radio and transport faults from audio faults.

Cross-stream statistics

In addition, an aggregate pass ranks which network conditions actually hurt quality in the capture, and optional per-subnet grouping shows where loss or jitter dominates.

Runs fully offline

Because the desktop edition processes everything locally, mobile operators can examine regulated subscriber traffic without uploading a capture anywhere.

VQ Monitor for live traffic

VQ Monitor combines waveform analysis with network monitoring to surface QoS and QoE issues on calls already running through the network.

Real-time call quality monitoring

Because issues surface as they happen, you can learn about customer-impacting quality problems early and act on them before subscribers start to complain.

Waveform and RTP analysis

Moreover, it inspects live traffic in detail, so echo, noise, jitter and silent calls are flagged at the moment they occur.

Fast deployment

In addition, VQ Monitor fits around your existing setup, so mobile operators can stand up a monitoring system that matches their business needs.

Built on PVQA

The scoring draws on Sevana PVQA, the same perceptual analysis engine used across the product range, so results stay consistent.

QualTest for active field testing

Because field conditions decide what a subscriber actually hears, QualTest runs as a mobile application for mobile-to-mobile call quality testing on site.

Test automation

You schedule the calls once, and the probe runs them automatically, so repeat field testing does not add operational cost.

Continuous voice MOS

Moreover, waveform analysis reports a MOS for the calls under test, which gives mobile operators an ongoing read on perceived quality.

Active and passive monitoring

Because needs differ by situation, you can pick the type of analysis that fits, whether that means placing test calls or observing real ones.

Quick setup

In addition, the probe is straightforward to deploy, so a working call quality monitoring setup can be in place in a day.
