...and also. What is right interface for this? Mixer component that says if voice call is active or not?

Your modem should be represented as a component in the system and have an input and an output representing the input and output on the cell network. See speyside for an example of how this can look in software though there's a bunch of different ways modems can appear so you might not have a fully digital link like that.

Thanks for the pointer.

With setup like that, how does userland tell kernel that the baseband <-> microphone/speaker connection should be activated?
