Answer 1

Can you explain what is the differences among them. Ok MIC is obvious but VOICE_CALL vs VOICE_UPLINK vs VOICE_DOWNLINK ?

VOICE_UPLINK: The audio transmitted from your end to the other party. IOW, what you speak into the microphone (plus surrounding noise depending on whether noise suppression is used and how well it performs).

VOICE_DOWNLINK: The audio transmitted from the other party to your end.

VOICE_CALL: VOICE_UPLINK + VOICE_DOWNLINK.
