Reply To: Low Audio Using Quintum A800


try adjusting the PSTN line gain

check current setting with
config line 1 2 print

Default value for both RX and TX on PSTN lines is 0. Range is from -30 to +6

Increase your values with the commands (put new value in place of ‘X’)

config line 1 2 rxgain X
config line 1 2 txgain X
config submit

Increasing gain too much will introduce echo.
