Command
Set / query RX AVC / AGC configuration
This command sets the RX AVC / AGC (Automatic Volume Control /
Automatic Gain Control) configuration for the specified profile. The RX
AGC compensates for variations in audio gains from the landline side,
while the RX AVC tracks the ambient audio noise on the mobile side
and compensates accordingly. Both controls allow for a constant audio
level in the RX direction.
The setting is stored in non-volatile memory and persists across power
cycles.
