+MAVOL, Volume Setting

This command enables you to determine a volume level for a particular feature via a particular
accessory. The gain levels are saved in flex. Therefore, upon power up, the path active (mic,
speaker and alert speaker) will have these saved gain levels.
Note: The SMS MT volume is adjusted using the +MAVOL command with type "ring". The
RING value is related to the SMS alert, the MT call, and so on.
