How to make mobile test call from one mobile phone to another?
Using Sevana QualTest it is easy:

✅Measures quality of mobile calls with regular non-rooted Android phones and iPhones
✅Enables uploads and shares test results
✅Runs both active (with reference audio) and passive tests
✅May be integrated with QualTest Host and correspondent Backend to automate making and receiving mobile test calls
✅Measures quality of mobile calls in the field
Within QualTest one can easily setup these two test scenarios:
🔊 initiate test calls and measure MOS when installed as system application. It is available on rooted phones only. One can view / share / upload test results right from the phone.
🔊 initiate and accept calls without analysis on mobile phone. Rooted phone is NOT required. In this mode application notifies its desktop (Raspberry Pi) counterpart (Qualtest Host, further down QH) about progress of the call. QH handles audio streams via cable adapter and communicates with backend.

How to quickly setup SIP / VoIP call quality testing?

Using QualTest it’s easy:
🔘 Quick way to measure quality of SIP / VoIP call without installing complex software solutions
🔘 Runs on Linux (including ARM builds)/ macOS/ Windows operating systems:
🔘 Quality measurement is based on Sevana waveform analysis technology and network statistics such as packet loss, jitter etc (E-Model)

Sevana QualTest is a mobile testprobe GSM VoIP application that checks current network conditions and estimates voice quality in mobile and VoIP networks. The platform is designed for end-to-end and single-end call testing, as well as for gathering and analyzing call audio quality metrics. Measure network metrics for VoIP calls and use waveform analysis to correlate audio problems with network conditions.

QualTest mobile test probe is an application for Android-powered devices that can work in both VoIP and cellular networks. A powerful tool for end-to-end and single-ended call testing. Fully functional frontend allows easy set up of tests specifying calling and called parties, reference audio and devices. Reporting shows overall quality MOS scores throughout different time periods, successful and failed test calls and speech-to-text engine provides information on call audio contents. The system works perfectly with unrooted and rooted mobile phones and analysis can be performed as on mobile device itself as well as on the devices it is connected to (e.g. Raspberry Pi in case of regular unrooted phones).
