Mobile-to-mobile test and monitoring

Would you like to setup mobile-to-mobile test call or monitor end-to-end call quality on a set of mobile phones?
Sevana QualTest is the solution that lets you establish this within one business day and receive full details on the quality score (MOS) and audio issues that have potentially degraded the call quality.
Analysis is performed directly on the phone, or one can have multiple phones connected to an USB port to make simultaneous tests.
All test results are aggregated directly at the backend of your choice.This can be Sevana QualTest backend or your existing monitoring solution.
Another option is to use one of easy integrations of QualTest, which our clients prefer most.

Mobile QualTest Sevana Test and Measurement

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.
