+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. This command is applicable for 
Analog and Digital modes.
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.
