before time ago have same problem searching lot found simple word solution https://stackoverflow.com/a/13090413/3514144 come know voice_uplink: audio transmitted end other party. iow, speak microphone (plus surrounding noise depending on whether noise suppression used , how performs).

voice_downlink: audio transmitted other party end.

voice_call: voice_uplink + voice_downlink.
