This document discusses using Sevana tools to test call quality between mobile devices using Skype. Specifically, it proposes a demonstration of a Skype-to-Skype call quality test using regular Android Skype apps on mobile phones. The test would record call audio and analyze it using Sevana's AQUA and PVQA tools to generate MOS scores and other quality metrics. It outlines the typical test setup and flow, including host machine, mobile phone, cable adapter, and test management via a backend server.
