8.29. GAIND -- Set Gain of Incoming DTMF Tones
This command sets the gain of the incoming DTMF tones. The gain of the outgoing DTMF depends on 
the country that the Vortex is configured for (see the 
COUNTRY) command. This command is an alias 
for the 
GAINDIT command. It is provided for backwards compatibility with and ease of migration from 
the EF200. When possible, the 
GAINDIT command should be used instead of this command. 
This command is an integer command. See 
Section 6.2 for more information on this type of command. 
The minimum and maximum values for this command are -20 and 20, respectively. 
This command is saved to non-volatile memory only as part of a preset. The state of this command will 
be restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
