[Asterisk-Users] Low volume/ audio problems on TDM400 card

[Carlos Rojas]

Hi,

I solved this problem in zapata.conf file

;rxgain=0.0                             ;Volume RX
rxgain=8.0                             ;Volume RX
;txgain=0.0                             ;Volume TX
txgain=1.0                             ;Volume TX


Regards
