output audio (microphone) not working, Android 6, Vernee Thor, speaker is fine

+2 votes

It might be a general problem with app permissions because CSipSimple has the same problem.

I can call up and reach my sim mailbox. Hear anything, keys are working fine and so I can control my mailbox.

But with any telefone on the other side: Nobody can hear me.

Any suggestions?
