Confirmed with my Motorola C350 cellphone. It appears to accept S16_LE, MU_LAW 
and A_LAW formats, 8 kHz sample rate, but actually records no data and plays no 
sounds (even if a cal is in progress).

One question: what playback and recording functionality is available on this 
cellphone under Windows?
