Sevana brings clear call quality testing and monitoring to VoIP, VoLTE and 2G to 5G, so you can hear exactly where quality breaks down and fix it fast.
From a single audio file to a live carrier network, we cover voice quality on both the audio and protocol levels. Our perceptual engine scores what callers actually hear, while network metrics explain the transport. As a result, you get one clear, trustworthy view of quality, whether you test in a lab, watch live VoLTE traffic, or analyse a packet capture afterwards. For more than a decade, Sevana has helped telecom teams worldwide turn that insight into better-sounding calls.
