No audio recording

[Koshub]

Thank you for your work on baresip! Is it possible to understand how it should work? It seems the audio module doesn't record the audio. How to check is it active at all? Use baresip version 1.0 with EXTRA_MODULES='g711 srtp audiounit avcapture opus'

Something is wrong with the audio and the connection is terminating due, for example, Audio stream timeout (message from Blink client logs).

What I make working is only the version that uses the CoreAudio framework. For example from this repo where the baresip version is 0.4.20. And that works only because it contains already compiled libs. For now, it is not possible to compile that stuff since iOS14 SKD is no longer supports a lot of the symbols from there.

Is there any support for iOS?

[Koshub]

Ok. The configuration process is not so clear. I think this should be applied by default on iOS target for config default template (not the CoreAudio one since it doesn't work in baresip for iOS):

audio_player        audiounit,default
audio_source        audiounit,default
audio_alert     audiounit,default
module          audiounit.so
