Command
Set audio settings to default values
This command sets all the configurable audio parameters to default
values. The default values are also loaded into non-volatile memory.
Set / query the DTMF TX gain
This command sets the DTMF TX gain for the specified audio profile.
The DTMF TX gain determines the gain, from -84dB to +12dB, for the
DTMF tone that is transmitted over the air.
This setting is stored in non-volatile memory and persists across power
cycles. The change to the audio system takes effect when a phone call
is made or received.

You can calculate the gain in dB using this formula:
Gain = 20 log
Note: In the command, <value> is in hexadecimal format. In the
formula, convert <value> to decimal format.
Description
