GAINSIT command.
Sometimes, the tones are played out to the phone, and the gain is adjusted by the GAINSOT
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

preset.
