So it should work with real I/O on Android device without TGVOIP_USE_CALLBACK_AUDIO_IO flag, right?

It needs some code modifications. Right now the library uses files as the Audio Device Module instead of hardware microphone/speaker. It's not enough to simply remove TGVOIP_USE_CALLBACK_AUDIO_IO. I can replace ADM with real devices and try to build an android version by your request.

Рейтинг работы был значительно улучшен.
В начале каждого звонка с увеличенной задержкой (latency) тишина до 5 секунд. Она мешает правильному измерению качества. Пример семпла из датасета:

entry1366_sample14_1610bcfe3d4a5409ca90463ea8c0ef8f.pcm_3GDelay_5445190.wav

После временного ухудшения сетевых условий качество не возвращается к норме даже после того как сеть вернулась в норму. Примеры:

Trying to rebuild library to use our coturn server address. Build fails:

If I remove override keyword in

then, it builds, but fails with segmentation fault during call:

Please make sure you replaced WebRTC M80 (included in my Stage 2 submission) by M81 (included in my Stage 3 submission).
Also run your own tgwss (singaling) server please, sources are included in the submission.
And one more note, try to increase IO timeout from 5 to 10 sec - TgVoip.cpp line 81 to avoid connection loosing with signaling server on low quality networks.

Were there any attempts to build library for Android with real I/O etc, as was requested in previous contest stage?

https://contest.com/voip-contest-2/entry1281

Don't see any mentions about it in sources.

There is no any problem to build the library for an android supported platform. The library depends on WebRTC (http://webrtc.github.io/webrtc-org/native-code/android) and libwebsockets (https://github.com/warmcat/libwebsockets/blob/master/contrib/android-make-script.sh), both are android friendly, and rapidjson which is header-only C++ library and can be used with any NDK project.
Nobody added any issues yet...
