Sorry I meant ibphoneui.conf. There you will find for the GTA02:

speaker = Headphone Playback Volume
microphone = Mono Playback Volume
microphone_mute = Mono Mixer Sidetone Playback Switch

This are the three controls which libphone-ui will adjust for
speaker/microphone volume and muting the microphone (you will also find
them with alsamixer).
