Sevana helps VoIP service providers keep call quality high across SIP trunks, hosted PBX and wholesale routes. You can analyse recorded captures offline, monitor live traffic in real time, and run scheduled SIP test calls, so you can prove quality to customers and resolve issues quickly. Three products cover that ground: Pcaptix for offline analysis from packet captures, VQ Monitor for real-time monitoring of live traffic, and QualTest for active SIP call testing.
Pcaptix turns a .pcap or .pcapng into clear SIP and RTP analysis, so VoIP service providers can settle a quality dispute or chase a codec problem straight from a capture.

Because Pcaptix lays the signalling out as a call-flow ladder and lists every request and response with headers and SDP, a failed registration, a codec mismatch or an authentication loop is easy to spot.
Moreover, each stream earns a Sevana perceptual MOS beside a network-estimated MOS, so you can tell a transport fault from an audio fault on G.711, G.729, Opus and more.
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 a route.
Because the desktop edition processes everything locally, you can analyse confidential customer traffic offline, while the web edition suits a quick capture or a demo.
VQ Monitor combines waveform analysis with network monitoring to surface QoS and QoE issues on calls already running through your network.
Because issues surface as they happen, VoIP service providers can learn about customer-impacting quality drops early and act on them before subscribers start to complain.
Moreover, it inspects live traffic in detail, so echo, noise, jitter and silent calls are flagged at the moment they occur and mapped to the network conditions behind them.
In addition, you can integrate the analytics module into your existing system, which adds quality KPIs and configurable thresholds without a forklift upgrade.
The scoring draws on Sevana PVQA, the same perceptual engine used across the product range, so results stay consistent from capture to live monitoring.
QualTest is a network test probe for quick quality measurement of SIP calls, built for end-to-end and single-ended testing across your routes.
It gathers network statistics and uses waveform analysis to surface QoS and QoE issues, so you see both what the network did and what the caller heard.
Moreover, the software probe installs with full configuration in a few minutes, so a new route can be under test the same day.
In addition, you can upload and share test results to keep your team informed, and collect network statistics for continuous analysis.
Because waveform analysis links audio faults to the measured conditions, you can show why a call sounded wrong instead of guessing.
